Evaporated milk
That being said, if you're searching for a coconut milk alternative, you're better off opting for evaporated milk so you don't have to dilute the sweetness or mix it with other tastes in your meal. It is an excellent substitute due to its flavor and resistance to curdling in high temperatures.
You may use evaporated milk to thicken soups, stews, and any other recipe that calls for coconut milk. If you intend to use evaporated milk in baking, dilute it with water to reduce the fat concentration. You may also use a low-fat form of evaporated milk, which is usually marketed alongside the regular variety. Furthermore, because evaporated milk is shelf-stable, you may stock up on many cans without fear of deterioration for up to a year provided they remain unopened.
