In a small saucepan combine mint leaves, maple syrup, and water. Bring to a boil, reduce heat and simmer for 2-3 minutes. Pour syrup through a fine sieve into a medium mixing bowl. Allow to cool and refrigerate until chilled or overnight.
Combine 1/2 cup chilled mint syrup with yogurt. In another large bowl, mix the strawberries with 1/4 cup syrup. Distribute the mixed yogurt into 6 individual bowls then top them with the strawberries.
Serve immediately.
Retain the remaining mint syrup for other desserts.
