Either
refrigerate the coconut milk can overnight, or open and freeze about 10
minutes. (I store a can in the fridge so there’s always one ready to
go. Be sure to use full-fat canned coconut milk for this recipe. Try not to shake the can, because you want the cream separate from the water underneath.)Once
cold, open the can and transfer only the thick part to a bowl. Discard
the watery part, or save for another recipe. Using either a stand mixer
or hand beaters, whip the
cream until smooth. Add remaining ingredients and whip until it forms a
mousse-like texture.
