Place dried tangerine peel in a small bowl and add hot water to cover. Let soak for 15 to 20 minutes, or until the tangerine peel softens. Drain and finely slice. Transfer 2 tablespoons of sliced tangerine peel to a bowl. You can save the rest of the rehydrated tangerine peel in an airtight container in the fridge for next time or discard it. If you do not use dried tangerine peel, grate an orange to make 1 tablespoon orange zest, or thinly slice 2 tablespoons of tangerine peel (*Footnote 2).
