Meet Black Garlic's Little Sister, Black Onion. After years of experimentation, we finally found the recipe. We use 'normal' yellow onions that we put in ovens for weeks. The result is a black onion, which, like black garlic, is a natural seasoning that is bursting with healthy properties. Unique and soft in taste, smooth in texture. The taste is best described as: subtle hints of soy, balsamic and raisins. This makes black onion an attractive delicacy. Flavour Black onion is a natural flavor enhancer! It has a deliciously full umami flavor. A great alternative to E-numbers. 100% natural
