If you plan to drink your coconut milk right after you make it, then chill your coconut cream in the fridge for 1 day before you whip up your DIY beverage.
Use the same ratio to create larger quantities of coconut milk. For example, for 4 servings, or 1 cup (240 mL), of coconut milk, mix 4 tablespoons (59. 15 mL) of water with 12 tablespoons (170. 1 grams) of coconut cream.
Alternatively, use a hand mixer to blend the coconut cream and the water.
