Thank you @kaclp Kristen and @RightNOW PJ.
Every little nugget of information helps. Trying to figure out how much to buy pretty clearly depends on how much I’d use every day. One pound isn’t worth buying if I’m going to use 4 oz a day. Kristen, your 20g of stearic acid per day works out to something close to 60g of cocoa butter, a bit over 2 ounces. That helps a lot. Two pounds sounds like a first order.
Right now I put a scoop of collagen in my coffee. If I put an ounce of cocoa butter in it, I’m going to need a bigger mug!
