Always use caution when blending any hot food in a blender or food processor. For either appliance, blend in batches, if necessary, and do not overfill. For a blender, use the low speed and vent it by removing the center area of the cover, so that any collected steam can escape. If desired, use an immersion blender, according to manufacturer’s directions.
For a more authentic Asian flavor, substitute light or regular unsweetened coconut milk for the half-and-half. Coconut milk is commonly available canned in the Asian-foods section of larger grocery stores. It should not be confused with cream of coconut, a thicker product often used in drinks.
