Curries or baking, I use coconut milk/cream often with my share of failures. I put it down to the variations in fat content between brands or when measuring out of a large container -which I then freeze for later use... Could freezing be the source of some of my issues? Or is graininess, splitting while cooking, small flecks of pure fat after blending, all signs of my inferior skills?
This is from http://www.realthairecipes.com "There are bags of frozen coconut milk available in some Asian groceries. While the flavor is better than canned, it separates and gets chunky when you heat it. I’m not sure why freezing does this to coconut milk. I’ve experimented with freezing my own homemade fresh-pressed coconut milk, and the same thing happens. The flavor is OK, but the consistency is quite odd. So, I recommend canned. If you are lucky enough to find Chao Koh brand coconut milk in a paper carton, this is even better."
*I prefer pure coconut in UHT packages (no gums or preservatives)
