The reason that first reaction takes so long is because acid esterification is a much, much slower reaction.
Lots of people think that it works just like a base reaction (heat, hit it for 2 hours & let it settle). Its really quite a different reaction.
So, yep, it's processing fine. It just takes longer on that first one.
I'd love to hear what you think of it once that first batch goes through.
We love ours.
