Bisque Ice Cream
One half-gallon of freshly turned clabber, one-half gallon rich sweet cream, one good vanilla bean boiled in one-half pint sweet milk, sugar to the taste. Churn this five minutes before freezing. One can of condensed milk may be used with less clabber. Mrs. H. L. S.
A frozen custard-free ice cream built on clabber — raw milk soured at room temperature until it sets. That single ingredient is what puts this recipe out of reach today, and the notes below explain why, along with what the rest of the wording meant to a Virginia cook.
- Clabber is uncontrolled raw-milk fermentation"Freshly turned clabber" is whole raw milk left in a warm room until wild lactic bacteria thicken it to a soft junket. Nothing in the process is pasteurised, measured, or heated, so any Salmonella, Listeria, E. coli O157:H7 or Campylobacter present in the milk survives and, in the warm souring stage, may multiply before the acid drops far enough to check it.
- Nothing in the recipe ever reaches a safe temperatureAlmost nothing in the recipe reaches a safe temperature -- Only the half-pint of milk for the vanilla bean is boiled. The clabber and the sweet cream are combined cold, churned five minutes, and frozen. Freezing does not kill pathogens; it preserves them. Roughly a gallon of unheated raw dairy served cold to a table of people is the exact situation modern dairy law was written to prevent.
- Modern milk will not do this anywayPasteurised milk lacks the native flora that turns raw milk to clabber. Left out, it spoils with putrefactive bacteria instead of setting. A cook following this recipe with supermarket milk gets rotten milk, not clabber. If you want a tangy ice cream, use a current recipe built on cultured buttermilk or crème fraîche from a pasteurised base.
- What the quantities meantA half-gallon is two quarts, so the finished mix is roughly a gallon before freezing — a large old-fashioned churn's worth, twenty-plus servings. "One-half pint sweet milk" is one cup. "Sweet" milk and cream simply mean fresh and unsoured, as opposed to the clabber.
- "Churn" and "freeze" are two separate machines"Churn" and "freeze" appear to be separate steps -- Churning five minutes here seems to mean agitating the mixture to break up the curd and smooth it before it goes into the ice cream freezer, a bucket packed with cracked ice and rock salt around a hand-cranked can. The wording "before freezing" reads as distinct from the freezing itself.
- The condensed milk variantSweetened condensed milk was a common late-nineteenth-century substitute for part of the dairy and much of the sugar. Substituting it for some of the clabber reduces the raw fraction but does not make the dish safe, since the remaining clabber is still unheated.
- Vanilla beanOne bean boiled in a cup of milk is a standard infusion; the recipe does not say whether the bean was split or the milk strained. Infusing vanilla in warm milk remains a common way to flavour a frozen dessert.
Housekeeping in Old Virginia (Marion Cabell Tyree, 1878) is a compilation of contributed receipts, and the initials "Mrs. H. L. S." mark this as one household's version rather than a standard formula o tato taste and the churning time is the only number given for method. "Bisque" in American ice-cream vocabulary of the period usually pointed to a frozen cream enriched with crushed macaroons or almond biscuit, the word generally traced to biscuit rather than to the soup; here it appears to be used loosely for a rich, thickened cream, with the clabber supplying both body and tang. Clabber itself was an everyday Southern and Irish-descended staple, eaten with sugar and cream or nutmeg, and it existed because every household with a cow had milk that soured faster than it could be drunk. Recipes like this one belong to a dairy economy that ended with pasteurisation and refrigeration: the ingredient was free, reliable, and on hand.
