Place 3 cups cashew milk in a double boiler.
Over medium to low heat, cook it down for 30 minutes to 1 hour, depending on how hot your burner is, stir it occasionally. Reduce it so that it is about half the amount you started with. I cooked mine on fairly low, because I didn’t want it burn, so it took a while. Stir it once in a while.
The canned versions of alternative evaporated milk started disagreeing with me, but this has not caused me any problems. It has been used in all my recipes that call for evaporated milk and has worked just fine. I have not tried this with any other alternative milks.
This is very easy to do, the hardest thing about it is the time it takes to cook down, but you can get it started and work on other things while this comes together!
