Step 1

Bring uncooked rice blend and 1 cup water to a boil in a small saucepan. Reduce heat, cover, and simmer until tender and water is absorbed, about 18 minutes. Remove from heat; let stand, covered, 10 minutes. Fluff with a fork.

Step 2

Add coconut milk, maple syrup, and 1/2 cup water; stir to combine. Stir in cinnamon and a pinch of kosher salt. Return to low heat and simmer until slightly thickened, about 5 minutes. Remove from heat; fold in frozen raspberries. Transfer mixture to a bowl set in an ice-water bath; stir occasionally until chilled. Serve with more maple syrup, fresh raspberries, and toasted unsweetened coconut flakes, if desired.
