Raspberry-flavoured, Red-currant Water

Eau de groseilles framboisée (raspberry-flavoured red-currant water) teaches restraint. The one true thing to know before touching a pan is that no pan belongs here. Red and white currants provide the bright, tart body, ripe raspberries provide the perfume, and heat would cook that perfume straight out of the bowl.

The original preparation assumed a basin, a silver spoon, a washed piece cut from block ice, a reliably cool pantry, and a saccharometer waiting to judge the sugar degree. A fine-mesh sieve, a nonreactive bowl, a stainless-steel spoon, one large rinsed ice cube, and the refrigerator do the same work at home. Loaf sugar becomes caster sugar because it is still pure sugar but dissolves more willingly in cold liquid. Those details were the old kitchen's scaffolding. The raw sieving, the fixed proportions, and the cold twenty-minute rest are the dish itself, so they stay. The book's modest basinful already becomes one generous home pitcher, suitable for one cook and four to six glasses, with no further reduction needed.

Rub the fruit patiently enough to express its juice, but don't mill the seeds against the sieve until they turn bitter. That is the step that decides the drink. Keep the fruit raw from its first crush to the final glass.
