Carrot puree is included with your liquid amount and you will need to deduct it from your total liquid. It is not just an additive. When I use carrot puree, I soap with my 50/50 lye solution then carrot for the balance of the liquid or at times I mix with with coconut milk
Yes, you count the carrot puree as the 30 g, and the 70 g as the water. I, too, would add the puree to the oils and stick blend before adding the lye water. Helps you make absolutely sure it is completely blended in.
