Coconut flour as an alternative in recipes

You need a lot more liquid in than usual. Can be a bit gritty. A much of almond flour and coconut flour I find more agreeable.

I agree - it is very heavy. I tried it once replacing a quantity of flour - I think 50% - and the cake was so much heavier.

I don't think you can do a straight exchange, its quite 'heavy' and grainy.
