This dessert is light and refreshing, with a lemony tang. It is made with the flesh of a young coconut, also called Thai coconut, which is found in health food stores and Asian markets. Look for coconut pre-cut into a white cylinder with a pointed top. Because these coconuts are young, their flesh is soft and creamy.
2 cups (500 mL) water
2 cups (500 mL) young coconut flesh
1 1/2 cups (375 mL) fresh lemon juice
1 1/2 cups (375 mL) light agave syrup
Blend all ingredients until smooth. Freeze about 1 hour; then transfer to an ice-cream maker and follow manufacturer’s instructions. If you don’t own an ice-cream maker, freeze in a shallow pan and stir occasionally until ready to serve.
