Butter Taffy
3 cups brown sugar 1/2 cup molasses 1/4 cup water 1/4 cup vinegar 4 tablespoons butter 1 teaspoon vanilla Boil sugar, molasses, water and vinegar. When crisp in cold water add butter and vanilla. Cook 3 minutes. Cool on buttered pans and break into pieces.
A plain hard-crack taffy of the sort candy chapters open with. The whole recipe hinges on one test, and a thermometer removes the guesswork.
- "Crisp in cold water" means hard crackDrizzled syrup should set into brittle threads that snap rather than bend, which is 300-310F on a candy thermometer. At the softer ball and crack stages the taffy will stay tacky and pull rather than break.
- The three minutes after the butterAdding four tablespoons of butter will drop the temperature of the syrup, and the further cooking brings it back up. A thermometer is more reliable here than the clock; the recipe sets no target, but the syrup wants to be back at the hard-crack stage, and pushing much past it risks scorching the brown sugar and molasses.
- Vanilla goes in off the heatThe original adds it with the butter, but the alcohol and aroma boil off immediately at these temperatures. Stir it in at the very end, after the pan leaves the burner.
- Vinegar is doing chemistry, not flavourAcid inverts some of the sucrose so the candy sets glassy instead of turning grainy. Plain white vinegar is the safest choice; at this quantity it should read as little more than a faint sharpness in the finished sweet, and a flavoured or aged vinegar would be more obvious.
- MolassesUse unsulphured light or dark molasses rather than blackstrap, which can turn bitter at this concentration. British black treacle is the nearest equivalent, though it is darker and stronger than light molasses and will push the flavour that way.
- Pan and pouringButter a rimmed sheet pan generously, or use a silicone mat. Pour without scraping the sides of the saucepan, since crystals clinging there will seed the whole batch.
- Breaking and storingScore the sheet with a buttered knife while it is still warm and flexible, then snap along the lines once cold. Yield is roughly a pound and a half; keep it airtight, as brown sugar candy goes sticky in humid air within hours.
- Safety at the stoveSugar at 300F causes serious burns and the syrup foams when the butter goes in. Use a saucepan at least three times the volume of the syrup.
Taffy of this kind belongs to the American molasses-candy tradition that ran through the nineteenth century and into the twentieth, when brown sugar and molasses were cheap, commonly kept in the house, and did not require the careful handling that white sugar work demanded. Cookbooks of the period often give candy its own chapter because pulled and broken taffies were made at home for parties rather than bought; the "taffy pull" as a social evening is well documented in American writing from the mid-1800s onward, though this particular recipe is poured and broken rather than pulled. The instruction to test in cold water rather than to read a temperature is the older method, standard until domestic candy thermometers became common; "crisp" here corresponds roughly to a stage on a ladder of terms - thread, ball, crack - whose names and divisions varied from one period source to another.
