I use organic coconut oil for popcorn all the time. It tastes awesome and is good for you. Even if does not taste as good as other oils, dont you care enough about your health to make the switch? Trans fats are horrible for you.
Before the one or two people on the board who will bring up saturated fats in coconut oil, do some research on it first. There are different kinds of saturated fats and coconut oil is very healthy, but like any other oil it is high in calories.
