Can I use unsweetened baking cocoa raw, or do products with it in it need to be cooked? I'm asking because I found a recipe online for an ice cream that calls for baking coco, but doesn't call for cooking. I've used baking coco before to make hot chocolate, but it seems that it wouldn't dissolve fully if not first put in some sort of hot liquid, even though it's finely ground. If not, do I need to treat it differently before putting it in a recipe?
If we are talking about something like Hershey's (the brand I know) unsweetened cocoa powder (the dark reddish-brown very fine powder), it can be mixed with cold milk if you make a paste of it first, and then dilute it to the consistency you want. I.e. start with the powder, pour in the milk bit by bit stirring and "mashing" as you go so as not to let any of the powder float on the milk. This cocoa powder also mixes easily with oil &amp; fat, so that property should help with your ice cream ingredients which probably have some butterfat included.

If your recipe includes only ingredients and no instructions, perhaps that paste technique can help.
