Tomato Jam

Confiture de tomates (tomato jam) teaches the first law of preserves: the set must come from somewhere. Tomato brings perfume, colour, and sweetness, but almost no cohesive power of its own. Red-currant juice supplies that structure, vanilla turns the fruit unmistakably toward confiture, and neither is optional. Before you touch the pan, know this: five pounds of tomatoes are only the beginning, because the usable drained pulp may be barely one pound.

The original recipe assumed a jam kitchen comfortable with small-ball sugar, a copper preserving pan, and a napkin stretched between the legs of an overturned stool. At home, a wide stainless-steel pan, a thermometer, and a jelly bag set over a deep bowl do the same honest work. The stool and paper-and-string sealing are scaffolding and can go; the full draining, sugar equal to the pulp by weight, vanilla, red-currant juice, and final nappe cannot. Clean lidded jars and refrigeration replace the paper seal because this adaptation is not a tested shelf-stable canning process.

Done properly, the confiture is garnet-red and translucent, thick enough to fold from a spoon yet soft enough to settle around cheese or a slice of terrine. One cook, one stove, one evening. The step that decides everything comes first: let the tomato pulp drain until it has no loose water left.
