Different Mincing Methods Can Affect the Taste of Garlic

The fact that microplaned garlic is more pungent than minced isn’t particularly shocking in and of itself. We all know that garlic’s intensity in a dish isn’t just dependent on how much garlic there is, but also how it’s been prepared: a single whole clove will deliver less intensity than a crushed one, a crushed clove will be milder than a sliced clove, and a sliced one isn’t as pungent as a chopped or pureed one—the more cells we rupture when cutting garlic, the more potent it is.
