What is the flavor profile of leeks?
The flavor profile of leeks is often described as a mild and sweet version of onions, with a hint of freshness and a slightly crunchy texture. Unlike onions, which can be overpowering and pungent, leeks have a more delicate and refined flavor that is often used to add depth and complexity to dishes without overpowering other ingredients.

How do leeks differ from onions in terms of taste?
Leeks and onions are both members of the Allium family, which means they share some similarities in terms of their flavor and aroma. However, leeks are generally milder and sweeter than onions, with a more delicate and refined flavor that is less likely to overpower other ingredients.
