Yuzu, or Japanese citron, is used mostly for its zest. It has a clean, sharp taste which is neither lemon nor lime. Dried yuzu is sometimes used with spices, and its juice is added to various one-pot simmered dishes. The flavour is a mixture of lime and tangerine.
Pomelo. A citrus fruit similar in appearance to a grapefruit with one slightly pointed end. Once the thick skin is peeled, the segments need to have the tough leathery coating pulled away. Inside, the flesh can be deliciously sweet and juicy. It is better left for a few days after picking before it is eaten. There are pink and white versions. The peel is candied and eaten as a delicacy.
