There is no middle ground on durian. You either love it or hate it. But if you can get past the stink, it is amazing food. It has a texture like custard with an intriguingly complex flavor profile. When ripe, the spiky husk starts to split open. Tear at these fault lines to get to the creamy fruit inside. It's best eaten in one sitting and immediately upon purchase. If you have to save it, remove the seeds, cut it into pieces, and freeze it. Later on you can throw it in the blender with some milk or yogurt and make durian smoothies.
