Philadelphia Ice Cream
1 quart cream 1 cup sugar 1 tablespoon vanilla extract Scald half pint of cream; add sugar and stir until dissolved. Cool and add remainder of cream and vanilla. Freeze as usual.
A three-ingredient formula that depends entirely on the quality of the cream and on how cold you can get it. Everything in "freeze as usual" is left to the reader, which is where most of the work lies.
- What "Philadelphia" means hereNo eggs, no custard, no cooking beyond a brief scald. The scalded portion is only there to dissolve the sugar cleanly; the flavor rests on the dairy itself, so use the best heavy cream you can buy, ideally not ultra-pasteurized.
- Half a pintOne cup. Heat it to just below a simmer, around 175F, until steam rises and the surface shimmers. Do not boil it or you will get a cooked, skin-forming note that has nowhere to hide in a recipe this bare.
- Chill the base thoroughlyThe instruction to cool before adding the remaining cream is the hinge. Refrigerate the finished mixture to 40F or below, and preferably overnight, or the churn will spend its cold budget lowering the temperature instead of freezing.
- Freeze as usualAt the time this would have meant a hand-crank bucket packed with cracked ice and rock salt, commonly given at roughly a 3-to-1 ratio by volume, cranked twenty to thirty minutes. A modern countertop machine with a pre-frozen bowl takes about twenty-five minutes.
- VanillaA tablespoon of extract is a heavy hand by current measure, though nothing else here is carrying flavor. Reduce to two teaspoons if your extract is strong, or steep a split vanilla bean in the scalded cream and strain it out.
- TextureWith no eggs and no stabilizer, this sets hard and turns icy within a day or two. Eat it soft from the churn, or ripen it in the freezer for two hours at most and expect to let it stand ten minutes before scooping.
- YieldAbout a quart and a half after churning, serving six to eight.
"Philadelphia ice cream" was a standing category in American cookbooks, set against "French" ice cream, which was built on a cooked egg custard. The Philadelphia style meant cream, sugar and flavoring and nothing else, and the name is generally traced to that city's reputation for the finest commercial ice cream in the country in the decades before the Civil War. Its appearance in a household cookbook says something about how domestic freezing had changed: ice was cheap and delivered, and a housewife could reasonably be told to "freeze as usual" without further explanation.
