In this lesson, you will learn about the vegetables in the allium family, which include onions, garlic, leeks, scallions, and shallots. Alliums are a foundational flavor in almost every cuisine around the world. The flavor of the world’s kitchens would be much less compelling if there were no alliums. Stir-fry dishes would fall flat. Mole sauces would be insipid without roasted garlic and roasted onions to lend complexity and grit.
