I braved adding the new sweetener to my lime water today, two spoons in a liter of water with four tablespoons of lime juice (big lime), and all was well. I think I added 4 or 5 spoons to my hot chocolate (32 oz carton almond milk), because it didn't sweeten at all and I added more. Does the hot beverage affect the ability of erythritol to sweeten? I dunno.
