I’ve heard from a lot of people that making coconut whipped cream has proven to be a serious challenge – often times they can’t get the coconut milk fat to separate from the water, even after the can’s spent a good 24 hours in the refrigerator. Unfortunately, this has little to do with your cooling chamber and a lot to do with the stabilizers used to keep the coconut milk fat suspended in the liquid; the ingredients in some cans just won’t allow the two to separate.
Stabilizers aside, the other culprit is too much air – which you can avoid by picking up the can of coconut milk and giving it a gentle shake. If you can hear the liquid sloshing around, you need to put it back on the shelf – chances are this can is a dud as far as making coconut whipped cream is concerned. What you need to listen for is a small pocket of air that moves around, making a soft gurgley sound. This method has proven to be effective in finding cans of coconut milk that encourage milk fat separation. In other words, it’s never let me down. Not once.
If you don’t feel confident in your ability to differentiate between sloshing and gurgling, Thai Kitchen will be your best (and safest) bet. In my experience, it’s the only brand of coconut milk that has consistently produced good quality whipped cream. If you’re rolling your eyes because their cans are lined with BPA – I knooow. It pains me, but I suck it up and buy it because I’m not a fan of buying $2 cans of coconut milk that yield separation only 50% of the time. Which is what usually happens when I bring home Native Forest coconut milk with high hopes of turning it into whipped cream. When in doubt, buy a few different cans and experiment to see which brand works best for you. But for the love of Buddha, do not try to speed up the process by freezing the can. You’ll be left with a solid block of coconut milk and a half-exploded can. Not that I know from experience, or anything.
Update: The issue with Native Forest coconut milk appears to be the source. Milk sourced from Thailand typically separates, while the milk sourced from Sri Lanka usually does not.
