Tangerine Ice

Glace à la mandarine teaches one exact thing: zest belongs in boiling syrup. Heat draws out the fragrant oils that a cold infusion leaves clinging to the rind, then cooling fixes that perfume in the sugar before the fresh juices arrive. The finished ice tastes of tangerine first, with orange giving breadth and lemon cutting a clean edge.

The source assumed a boiler of syrup ready for service, a syrup gauge, and a freezing pot tended in salted ice. Your equivalents are a small saucepan, an optional refractometer, and a countertop ice cream machine. I have halved the brigade quantity to approximately 425 ml of syrup, zest from two tangerines, and juice from three tangerines, one orange, and half a lemon. No flavour ratio has changed. The syrup gauge itself is scaffolding, and a refractometer replaces it; the boiling zest infusion is the dish and stays untouched. One cook, one stove, one evening.

Take only the zest, the glossy coloured film of the rind, because white pith turns the clean citrus perfume bitter. Before you touch the pan, have that zest ready beside you. Adding it the instant the syrup boils is the step that decides the dish.
