Hi Jesse >Hi Keith, Tom, >Thanks again for this useful information. But please, on the Super Easy >Titration Chart: what "lye water"? Lye mixed with water, okay sure, but >no, wait, how much water? I'm very confused. >Jesse
It means millilitres of 0.1% NaOH solution, which is what's used in titration to find out how much lye (NaOH) is needed to neutralise the extra Free Fatty Acids (FFA) in the oil. The longer and hotter the oil is cooked the more FFA it contains. More about lye How much lye to use?
