Well, I’ve settled on Oatside, which tastes good in coffee. And to enhance the frothing, I add 2% dairy milk with 18% protein (for enhanced frothing). I get great thick cappuccino microfoam with ½ Oatside and ½ milk, so I am going to try ⅔ Oatside and ⅓ milk. The amount of dairy milk is very small, and the rest of my diet is all alternative milk, so all is good.
