Say I'm working on a juice recipe that takes 3 flavors, and when I try it I think it needs a little more of one of the ingredients. Say it needs to be upped by a half percent. Is it possible to re-use the sample batch I made, and how would I calculate the amount I would add? By just adding more of one flavor, I'd be increasing the total volume of the batch, and throwing off the percentages of the other ingredients.
