I used to make a lot of cakes using tapioca flour. Now I've moved to another country and rarely stumbled upon the flour in the supermarket. Last time I found gari which also made from cassava. Can I substitute gari for tapioca? Can I put it in food processor first to make the texture more similar? From what I've read, usually gari's mixed with water to make porridge, but I don't have a lot of ideas in how to use it (other than all my tapioca flour recipes).
Thank you.
