Yuzu are extrememly fragrant. The flavors and oil are concentrated in the rind of the small fruit (about the size of a golf ball). Yuzu limes, botanically classified as Citrus junos, are highly fragrant fruits that belong to the Rutaceae family. Believed to be a hybrid between the satsuma mandarin and the ichang papeda, Yuzu limes are not botanically a lime but have earned this title since they are seldom consumed as a fruit in the traditional sense and are utilized for their tart and aromatic juice and zest. Yuzu limes have been used for centuries in Asia as a lighter, tangier, and floral forward flavoring in sauces, marinades, andressings.
