Mine is much like yours except I don't measure. Just kinda eyeball. Plus, I don't use water. Coconut milk all the way for me. Makes it richer tasting, I think. And I'll add a couple drops of coconut extract and if I feel like it, some grated coconut too.

I wish I had the recipe for the one at Yama's. Sooo good! Mine comes close, but not close enough.
