Ice Cream Recipe Review: Van Leeuwen's Vanilla Ice Cream

  “Vanilla Ice Cream” on page 37 of Van Leeuwen's Artisan Ice Cream Book by Laura O'Neill, Ben Van Leeuwen, Pete Van Leeuwen, and Olga Massov.

I made this ice cream FOUR times before I felt like it was at all reasonable to review it.  The first two times were failures, and despite all my research, I still don't know why. The third time was a failure for a different reason, one that was entirely my fault, and the 4th time was an unmitigated success producing a wonderfully rich, smooth ice cream.

This ice cream uses eight egg yolks for a quart-sized batch.  Yes, you read that right - EIGHT.  The ice cream is very nearly yellow in color.  The recipe lacks both a liquid sugar or any sort of stabilizer, but I suspect the extreme number of yolks may keep the ice cream smooth despite that, though I'm curious to see if it remains smooth after a couple of weeks in the freezer.

For the first three tries, I was still using up older stock of Madagascar vanilla beans, and for the fourth try I finally got to use my newer Vanilla Bean Kings stash. 

First try (failure): I used the no-temper technique (placing all ingredients while still cold into the pan) in a sauce pan using medium heat (as normal) and whisked nearly continuously until it reached 170F/77C and when it was done cooking it was nice and smooth, but once the custard cooled, it had turned grainy (before going into the churn). I don't think the problem could be with leaving the bean pod in the custard overnight - I always do that, and it's never caused graininess before.  The ice cream was an abject failure. Good flavors, but absolutely terrible, grainy texture. Overall, it was a 3 out of 10.  Other than giving a few samples away to family, I tossed it.  

Second try (failure): Same as above, but I cooked the custard on medium-low and used not one but TWO thermometers - a probe-style clipped to the pan, and also regular checks with the instant-read.  This, too, was smooth while hot and grainy once cool.  I rescued this one by running it through the Vitamix before churning, and that raised its score to maybe a 7/10. Still not where it should be, but definitely worth eating.

Third try (failure): For this one, I followed the recipe EXACTLY (except for leaving the bean pod in the custard overnight), even using a double-boiler. I did notice that the quality of the creme anglaise was better than usual when the cooking was complete. The graininess was still there the next morning, but MASSIVELY reduced, like by 90%.  I also re-read the sidebar which suggests blending the bean pod in with the custard, and I unthinkingly did so, which spoiled the experiment by adding a confounding variable).   I must not have blended it long enough because the texture was just  ... odd.  Almost, powdery, I guess? It was scoopable, though, so I don't think it was an emulsion failure, and the odd texture seemed to be from not-quite-fully processed vanilla bean pod bits.  I don't think the vanilla flavor was improved by blending the bean, so I won't be doing that in the future. I threw away the second half of the quart.

Fourth try (success): I used a bean from Vanilla Bean Kings (is it possible that the problems with the previous tries were with the beans I was using?), and I again followed the recipe as written (though I left the bean pod in the custard during the chilling process, removing it just before churning).  This time, I turned out perfectly and was delicious.

For whatever reason, this custard seems far more finicky than others, but that might be an unfair assessment, and I will be doing some testing to see what caused the graininess.   Like, can I get away with just a saucepan (instead of a double-boiler) if I add some liquid sugar and/or stabilizers? Or what if I use the double-boiler - is that enough to use the no-temper method even without the liquid sugar or stabilizers?  Or did I simply overcook it in the saucepan? (My instant read thermometer seems to register a cooler temperature than the candy thermometer.) I am really not sure what the tradeoffs will be. It'll be interesting to find out.

Substitutions and Techniques:

  • Turbinado sugar instead of white sugar (always) as I prefer the flavor for the first two batches.
  • I used white sugar for the third and fourth batches (as I'm trying to figure out the cause of the graininess).
  • This recipe uses only one vanilla bean, and no extract (I think I prefer vanilla ice cream to have both), but in the first batch, I accidentally used two vanilla beans, so the flavor was nice and strong despite the lack of extract.  How did I accidentally use two?  Before putting the milk/cream for this recipe in the freezer (I buy milk and cream in larger quantities, then freeze it in ready-to-go amounts), I split a vanilla bean and dropped it into the milk.  When I was ready to make this ice cream, I set the jar of frozen dairy in a pan of warm water to thaw, then started gathering my other ingredients. Forgetting that there was a bean frozen into the milk, I got another one ready to go and added it to the pan. Then I dumped the milk into the pan ... along with the second bean.
  • For the second batch, I used only one bean.
  • For the third batch, I used only one bean, but I blended it into the custard.
  • For the first two batches, I used the-throw-all-cold ingredients into the pan and cook until it hits 170F/77C technique (ie, no-temper technique), but for some reason, the custards were grainy.
  • For the third and fourth batches, I used a double-boiler, and did temper the eggs.

Results:

  • Custard 1: 
    • Same day: Grainy. Good flavor.
    • Next day: Terrible texture. Dry and very, very hard and grainy. The flavor was good. But it was bad enough to throw it away.
  • Custard 2 (blended before churning): 
    • Same day: Good flavor, acceptable texture.
    • Next day: Acceptable texture, reasonably scoopable, Flavor was good.  Much better than the previous batch, but definitely far from my best.
  • Custard 3 (radically reduced graininess that might just be the vanilla seeds, blended pod into custard before churning). Unfortunately, I don't think I blended the pod ENOUGH because it made it a little chalky.
    • Same day: kind of chalky from the blended pod.  Not sure I like that.
    • Next day: It's reasonably scoopable, even frozen hard. Texture is still off, but I think that's the fault of the pod, which I apparently didn't blend fully. I also don't think the flavor is especially improved by blending the pod, so doubt I'll bother with that again.
  • Custard 4: Delicious.  Just perfect both days.  

Uses:

  • I added dark chocolate chips, candied orange peel, and drizzled homemade orange syrup into the ice cream to make a ripple of sorts in two batches. I think ginger snap chunks would taste great with this combination, or maybe chocolate wafers (like Oreos, but better).
  • With the third batch, I didn't add any stir-ins as I'm having guests that weekend, and having vanilla ice cream on hand would be a good idea.
  • With the fourth batch, I added Oreo cookies and raspberry ripple.

Ice Cream Recipe Review: Rose Levy Beranbaum's Dark Brown Sugar Ice Cream with Black Pepper

  “Dark Brown Sugar Ice Cream with Black Pepper” from Rose's Ice Cream Bliss by Rose Levy Beranbaum.

  • My other ice cream reviews can be found here.

I can't find the recipe online except behind a paywall, so I've included the ingredients below, so you can get a sense of the flavors:

  • Dairy: 2 cups heavy cream and 1 cup whole milk
  • Eggs: 7-11 (I used 9)
  • Sugars: - 3/4 cup dark brown sugar and 2 tbsp liquid sugar
  • Other flavors: 1/2 tsp vanilla extract and a pinch of salt
  • Black pepper: Added as a "to-taste" topping when the ice cream is served.

I didn't like the black pepper as a topping very much - it felt out of place and didn't meld the flavors at all. We also managed to inhale it a bit from time to time, making us cough a little now and then as we ate.  I'm inclined to either add black pepper to a caramel sauce and layer that in, OR cook the black pepper inside a fine mesh bag to infuse the flavor, then remove it before churning. 

I didn't think the brown sugar flavor was quite strong enough, so I stirred in 2 tsp of molasses to the chilled custard (molasses is acidic, so it's best added when the milk is cold to avoid curdling the dairy). One family member thought the molasses flavor was too strong, and others liked it.  

Alas, my ice cream maker decided to leak coolant out the bottom (fortunately NOT into the ice cream), so I transferred the partially frozen mixture to my backup ice cream maker and promptly broke the hub assembly on the second bowl, so I finished churning by hand (just mixing it in the frozen bowl).  I went from two ice cream makers to zero in about 5 minutes.    I now have a replacement bowl (under warranty) and a new hub assembly on their way to me.  Obscenities could probably be heard at my neighbor's house.

Substitutions and Techniques:

  • I used brown sugar as the recipe called for instead of my usual turbinado.
  • I used glucose as the liquid sugar.
  • I (mostly) followed Rose's no-temper technique; I put the egg yolks into the pan, added the granulated sugar to them and beat them a little to combine. Then I added all the other ingredients except the vanilla, turned on the heat and cooked, gently whisking nearly constantly until the temperature passed 165F/74C and it was starting to thicken.  I didn't use a double boiler, and the texture was nice and smooth.
  • I transferred the mixture to my milk can, added the vanilla extract, and set the can in a sink of cold water. I mixed for a few minutes, then left it to chill for an hour before transferring to the fridge to finish chilling.

Results:

  • Same day: Nice and smooth despite the hand-mixed finish. Very nice flavor.  I think I'd recommend people start with 1 tsp of molasses to amp up the flavor, and add a second (as I did) if they like it strong.
  • Next day: Not as smooth as I'd like, but very very good considering how I churned it.

Uses:

  • Strawberry sauce goes nicely on it. I think an apple caramel sauce ribbon would be good, as well as graham crackers, or a cookies-and-cream variation using ginger snaps.

Ice Cream Recipe Review: David Lebowitz's Chocolate Ice Cream

  “Chocolate Ice Cream” from The Perfect Scoop by David Lebowitz.

  • The online recipe can be found here
  • My other chocolate ice cream reviews can be found here

I don't know if it's the double-boiler that caused this, but this is the smoothest egg-based custard I've ever made (despite not having a liquid sugar nor a stabilizer both of which really do help prevent iciness).  I also had some difficulty getting the custard up to 170F/77C, but I watched the consistency, and it thickened appropriately on the cool side - around 160F/71C.  I wonder if it's because the water level had dropped too much in the lower chamber of the double boiler?  It was far from empty, but it dropped an inch in the time I cooked the custard.

Note: to pasteurize an egg, it must be held at 140F/60C for 3.5 minutes. The custard was held at a significantly higher temperature for a significantly longer period of time, so the concern here wasn't with food safety, but whether it would achieve the right texture (it did).

Either way, once chilled, the custard was so thick (about the consistency of pudding cups I ate as a kid) I had to spoon it into the churn.   I must have managed the temperatures appropriately because I doubt it would have thickened so much if I hadn't. 

It's also very deeply chocolatey (which I appreciate in an ice cream).  I think I prefer the flavor of Fany Gerson's chocolate ice cream with mazapán (which tastes like a flourless chocolate cake in ice cream form), but this was really, really good.

Substitutions and Techniques:

  • Turbinado sugar instead of white sugar (always) as I prefer the flavor.
  • I used chocolate chips as the chocolate source.
  • I'm currently using a double boiler for my egg-based custards.
  • I used the no-temper technique I adapted from Serious Eats and Rose Levy Beranbaum. I placed the egg yolks into the upper chamber of the double boiler (while it was cold) and whisked them with 1/3 of the sugar. Then I added all the rest of the ingredients except the vanilla and chocolate chips, whisked it gently then turned on the heat under the double boiler.  
  • I filled the sink with cold water in preparation for rapid chilling of the custard.
  • The chocolate chips and vanilla went into my mini milk can that I use to chill the custard.  I poured the custard onto the chips, then placed the can into the sink of cold water to begin the chilling process.  
  • I whisked the mixture to melt the chips, and it turned a deep glossy, chocolatey brown (that glossiness is what you are looking for), and I continued whisking for a couple of minutes, long enough for it to cool to warm then left the can in the cold water for an hour before transferring the custard to the fridge overnight.
  • I churned at a faster speed than usual to decrease the richness a little. It lightened noticeably in color (as with a whipped ganache).

Results:

  • Same day: Silky smooth. The flavor is more deeply chocolate than the color would imply. Wonderful.
  • Next day: Excellent flavor and texture.  Not as scoopable as I'd like - still need to let it sit at room temp for 10 minutes first. 

Uses:

  • Chambord is delicious on this ice cream. 
  • I think a salted caramel ripple would be wonderful in it, or even some sort of banana ripple ... or any fruit ripple, really.
