Yellow stainer. A mushroom to be avoided. Some sources refer to it as toxic.
Either applies to verjuice or to an acid-flavoured sorbet made from almonds, verjuice and sugar. Popular in North Africa and Spain.
Verjuice. The juice of unripe, unfermented grapes, used for culinary purposes. It is quite sour, like lemon juice or vinegar, it is an acidulant, but it is much milder. Keeping verjuice in the bottle will have the same effect as for wine, although the acid flavour will not change. It is versatile and can be used effectively with fish, chicken or to cut fattier foods, or in vinaigrettes and dressings.
