Yuzu is a sour Japanese citrus fruit, used both for its juice and its aromatic rind. The yuzu (which is about the size of a tangerine) has an aroma and flavor that is distinct from any other citrus fruit, somewhat akin to a cross between grapefruit and lime.
In this recipe, a traditional vinaigrette gets an refreshing Asian makeover - perfect with fresh greens and with Seared Ahi Tuna!
Mix yuzu, soy sauce, sugar, wasabi powder, rice vinegar, Mirin, shallot and sesame oil together in a nonreactive bowl.
Add the peanut oil gradually in a slow, steady stream while whisking continually.
