I have always said I should, but I don't always follow through with it, weigh out ALL of your oils and ingredients separately before you touch ANYTHING else!
I had everything out, right? My milk ice cubes are sitting out, melting-ish to room temperature in a measuring jar (already pre measured and double checked to 8 oz!) and I had already poured my .4 oz of distilled water to get them going and bring my liquid up to where it needed to be. My oatmeal was out and ground. My olive and coconut oils were already weighed (2 big, brand new bottles, no problems there!). and as I was weighing out my shea butter, I totally forgot I only had about 4 oz in stock (exactly 3.8!), and the recipe required 5 oz.
Yeah. No. Not going out on a Sunday night to pick that up. Not happening. Not with the milk already melting and the only thing I had left to weigh was the lye. And I was already in it, because I mix all of my oils in one jar as I weigh them out because I heat them up together to get them up to temperature. I ended up winging it and threw in some more oil to bring my oils up to the total needed. We'll see how it turns out! Really, really not what I wanted. :think:
Superfat and lye amount stayed the same, but still.
