How does the flavor profile of the underground root bulbs compare to the leaves?
Answer
The root bulbs offer the most concentrated flavor, often leaning heavily toward garlic.
The different parts of the onion grass plant present varying intensities of flavor. The subterranean root bulbs are described as having the most concentrated flavor profile within the plant. While the leaves offer a sharp, oniony or garlicky taste suitable for fresh applications, the underground bulbs exhibit a flavor that leans significantly toward strong garlic. This intensity means the root bulbs require cooking, such as roasting or sautéing, to bring out a sweeter, mellow note, whereas the leaves are often preferred raw for their sharp bite.
