buttermilk-sweet corn ice cream with berry coulis
What to do when faced with two ice cream recipes that sound equally fabulous, and a bout of indecision? Combine them, of course!
I was recently invited to a weeknight dinner party and volunteered to bring ice cream, as I could make it ahead and just grab it after work on my way to the party. I love an excuse to make ice cream, because the flavor possibilities are pretty endless (if you don’t believe me, check out this article in the NY Times… scoop of Government Cheese, anyone?). I found out another guest was bringing a blackberry pie, so that helped narrow it down. I thought of a buttermilk ice cream I’d made last summer from Smitten Kitchen, but I also had in mind a sweet corn ice cream I’d had years ago at Tapawingo* in Ellsworth, MI. The restaurant served the ice cream with a berry cobbler and the combination was perfect. I was torn- which one to make?
I decided to throw caution to the wind and combine the two flavors (yes, I am being facetious, as I realize this won’t win any awards for all-time most daring ice cream flavor). Both recipes were originally from Claudia Fleming (author of well-loved dessert book The Last Course) and had similar proportions, so it was pretty easy to adapt the two by simply substituting buttermilk for the regular milk called for in the sweet corn recipe. I added half a vanilla bean for good measure, and crossed my fingers. The results were pretty spectacular if I do say so myself. The slightly tart buttermilk was a welcome counterpoint to the corn’s milky sweetness. In fact, I liked the pairing so much that I was thinking of trying to adapt this flavor combination into some sort of chilled summer soup- like a Midwestern chlodnik of sorts.
If you’re not serving this ice cream with a berry cobbler or pie, I highly recommend drizzling it with a berry coulis- the flavors are highly complimentary, and while the ice cream is great on its own, the berries take it to another level. If you don’t want to go to the trouble of making a coulis (although it’s quite easy), you could of course just scatter some berries alongside.
A couple of ice cream-making notes: Fleming’s recipes call for 9 yolks and 12 yolks, but I cut it down to 8 and it was just fine. You could even go with 6 if you wanted. The buttermilk is richer than the milk it replaces, so your result will still be plenty indulgent. As for making the custard base- there seems to be this great fear, perpetuated by many a cookbook, that custard-making is fraught with danger; that it might betray you at any moment, turning hopelessly into scrambled eggs. For years, I cooked my custards at much-too-low temperatures, sweating over them for eons, waiting in vain for them to magically thicken. Don’t be afraid to heat the mixture until you can see steam coming off it; otherwise you’ll be at it forEVER. As long as you keep up the stirring and don’t let it boil, you’ll be OK. Also, because of the high liquid ratio this particular custard doesn’t get very thick, so don’t worry if it seems wimpy; when it freezes it’ll be just fine.
*In searching for the restaurant’s website for this post, I was saddened to learn that Tapawingo closed its doors last year. Arguably the best restaurant in Michigan, they garnered all kinds of awards, stars and accolades. Like many Michigan businesses, they were forced to close because of the downturn in the economy. They will be sorely missed. In addition to breathtaking meals with a focus on local MI products long before it was trendy, the grounds and gardens of the restaurant were gorgeous. I can only hope someone decides to take up the reins and re-open something in that location, although they’d have big shoes to fill food-wise.
Buttermilk-Sweet Corn Ice Cream (adapted from two recipes by Claudia Fleming)
Note: As Ms. Fleming wisely points out, this recipe will only be as good as the sweet corn you use to make it. For optimal results, use local corn that has been picked no more than 2 days prior.
Directions: Remove the husks and cornsilk from the corn and break each cob into thirds. Cut the kernels from the cobs with a sharp knife, reserving the cobs. Put the kernels in a blender with the cream and buttermilk and pulse into a rough purée.
Pour the cream mixture into a heavy-bottomed saucepan, adding the corncob pieces, vanilla bean, salt, and ½ cup of the sugar. Bring to a boil, then cover and remove from heat. Let steep for one hour.
Remove the corncobs and discard. Fish out the vanilla bean and set aside. Strain the mixture through a medium or fine mesh strainer, pressing down firmly to expel as much of the liquid as possible; discard the solids*. Return to the saucepan and place over medium heat. Scrape the seeds from the vanilla bean, adding them to the cream mixture (if using vanilla extract, add it now).
In a bowl, whisk the egg yolks with the remaining ¼ cup sugar. Whisk in a little of the hot cream to temper the yolks, then add them to the saucepan. Cook the mixture, stirring constantly, until it coats the back of a spoon. Pass through a fine mesh strainer and refrigerate until thoroughly chilled (at least 4 hours). Freeze in your ice cream maker according to manufacturer’s instructions. Makes about 1 quart.
*I couldn’t help but think that rather than tossing it, this deliciously sweetened corn pap would be great in some sort of muffin or quick bread, but alas, I didn’t have a chance to experiment. And speaking of not wasting, you can rinse off the vanilla bean, let it dry, and blitz it with sugar to make vanilla sugar.
Mixed Berry Coulis
1 1/2 cups raspberries, washed
1 1/2 cups blueberries, washed
1/4 cup sugar
squeeze of lemon or dash of balsamic vinegar, optional
Notes: You can, of course, substitute other types of berries; you may just need to slightly tweak the sugar quantity. This recipe does not produce an overly sweet sauce; if you want a sweeter result you can up the sugar to 1/3 cup.
Place the blueberries and sugar in a pan over medium heat, stirring to dissolve the sugar. (The residual water from washing the berries should be sufficient, but if not, you can add a small amount of water.) Cook, stirring occasionally, until the berries begin to break down; you can encourage this process by mashing them with a fork.
When the blueberries have turned sauce-like, add the raspberries and cook for a couple minutes longer (these will break down very quickly). Taste the sauce and adjust if needed by adding a bit more sugar or a squeeze of lemon or small dash of balsamic. Strain the sauce through a chinoise or fine mesh strainer, pressing down on the solids (you may need to do this in 2 batches). You should end up with about 2 cups sauce and 1/2 cup solids to be discarded. Use as a sauce for ice cream, panna cotta or other desserts.
