I am making a very simple mix of the cacao and hot water. I dont have a scale but iirc Gabi said 20mg to 40mg of shaved cacao. I dont have a scale here, but i use a little chunk maybe 1/2 inch x 1/2 inch x 2 inches. Gice or take. I shave it by rubbing a knife edge against it to try to get it into a powder. You can always start with a smaller amount and add till you like it.
