Yes I want lecithin but it's very hard to find here in New Zealand. And, I bought granules once, but after a month or so they had gone bad and became a big clump. Do you use granules or powder? And guessing you use soy lecithin?

I also use Guar + Xanthan. Makes a difference. Also I use Maltodextrin in low fat ice creams to increase smoothness, that really helps!
