Someone who live in another country asked me to ask you "Experts" this - is the baking powder absolutely needed when making HHB?
She doesn't own an oven, had baked the blocks on skillet or recently tried using dehydrator, I think. Then she is wondering, if she isn't using oven, she still needs to add baking powder or not.
Is the baking powder only needed for raising batch, no other reasons? If so, she doesn't have to add baking powder, does she?
(I should have posted it in nursery. )
