Nectarines

Nectarines au Sirop teaches the quiet discipline of preserving fruit at the edge of ripeness: the syrup supports, but the fruit must still stand on its own. The one true thing to know before touching a pan is simple. Choose yellow-fleshed nectarines that smell ripe yet remain firm at the shoulder. Soft fruit will taste lovely, but after poaching and processing it belongs in compote, not in a jar of clean halves.

The source entry gives nectarines no separate formula. It assumes the cook can turn to the complete peach repertoire and use every method unchanged, which is exactly the right instruction: a nectarine is a peach without fuzz, and it peels and poaches the same way while holding slightly firmer. For one cook, the honest home equivalent is one peach preparation, au sirop, reduced to four 500 ml jars in an ordinary deep pot. The brigade catalogue is scaffolding; the unchanged peach technique is the dish. One cook, one stove, one evening.

Nothing is improved by cooking the fruit to tenderness before it is sealed. Bring it only to the point where a knife meets a little resistance, then let the water bath finish the work. That restraint decides the batch.
