纯素青酱品牌

为什么

传统配方是罗勒、松子、大蒜、橄榄油、盐和两种硬奶酪，这两种奶酪都使用动物凝乳酶制成。纯素青酱用腰果、营养酵母和味噌代替它们，现在大多数超市都有专门的品牌销售。

What is actually in it

Pesto Genovese has a protected recipe: Genovese basil, Ligurian olive oil, pine nuts, garlic, coarse salt, Parmigiano Reggiano and Fiore Sardo pecorino, pounded in a marble mortar. Both cheeses are DOP products made with animal rennet from calf stomachs, so classic pesto fails on two counts at once — dairy and slaughter by-product. Rebuilding it without cheese is mostly about replacing three functions: salt, glutamate and fat-emulsifying protein. Nutritional yeast and miso handle the first two; soaked cashews or blanched almonds handle the third and keep the sauce from splitting when it hits hot pasta. Pine nuts are expensive and increasingly substituted with sunflower seeds or walnuts even in commercial jars. Watch the chilled fresh-pesto tubs, which often add cream or mascarpone for a milder taste, and jarred pesto sold as vegetarian, which is not the same claim. A practical kitchen note: never cook pesto — loosen it with a ladle of starchy pasta water off the heat, or the basil oxidises and the sauce turns bitter and khaki.
