It can be used as custard for ice cream, or just as custard to go with desserts--I put it in a trifle.
- 2 cups heavy cream
- 1 cup whole milk
- 3/4 cup granulated sugar
- Table salt
- 5 large egg yolks
In a medium saucepan, mix 1 cup of the cream with the milk, sugar and a pinch of salt. Warm the cream mixture over medium-high heat, stirring occasionally, until the sugar dissolves and tiny bubbles begin to form around the edge of the pan, 3 to 4 minutes. (Add time if you're making more than one quart.)
This is where you infuse your choice of flavoring. Cover, remove from heat and let sit one hour. Taste and let sit longer if you want a stronger flavor. If not infusing, proceed with the recipe. (I didn't try infusing.)
Prepare an ice bath by filling a large bowl with several inches of ice water. Set a smaller metal bowl (one that holds at least 11/2 quarts) in the ice water. Pour the remaining cup of cream into the inner bowl (this helps the custard cool quicker when you pour it in later. Next time I will prepare the ice bath first, before mixing the custard ingredients. The bowl and cream will have a longer time to chill. Or skip the ice bath altogether if making your custard the night before.) Set a fine strainer on top of inner bowl.
In a separate medium bowl, whisk the egg yolks. If you have infused the cream mixture, re-warm it over medium-high heat until tiny bubbles begin to form around the edge of the pan, 1 to 2 minutes. In a steady stream, pour half of the warm cream mixture into the egg yolks, whisking constantly to prevent the eggs from curdling.
Pour the egg mixture back into the starting pan and cook over low heat, stirring constantly and scraping the bottom with a heatproof cooking spoon or rubber spatula until the custard thickens slightly (it should be thick enough to coat the utensil and hold a line drawn through it with another spoon) -- 4 to 8 minutes. An instant-read thermometer should read 175 to 180 degrees at this point. Don't let the sauce overheat or boil, or it will curdle. Immediately strain the custard into the cold cream in the ice bath. If using an infusion ingredient, press firmly in the strainer with a spoon or spatula to extract as much flavor as possible. If you want to add melted chocolate and cocoa, do so now. (I italicized that because I managed to skip over that sentence at least 6 times as I was desperately rereading the recipe, trying to figure out when to add the chocolate. And my custard was never very thick, but thick enough to hold a line.)
Cool the custard to below 70 degrees by stirring it over the ice bath. To add a flavor other than chocolate, set it into the cooled custard.
Refrigerate the custard until completely chilled, at least 4 hours. Then freeze the custard in your ice cream maker according to the manufacturer's instructions. If using mix-ins, fold them into the just-churned ice cream. Transfer the ice cream to an air-tight container and freeze solid for at least 4 hours.
Yields 1 quart.
