Dry cider

Fermented apple juice. In Normandy, Brittany and Asturias it's a cooking liquid as much as a drink — for mussels, pork, chicken and chorizo.

Knowing it

Where to buy
Dry, unpasteurised farmhouse cider for cooking; sweet commercial ciders make sauces cloying.
Worth knowing
Reduce it by half before adding cream, or the sauce will be thin and sharp.
