Barm and unsweetened pineapple juce question
I was exploring BBA today for the first time (I mostly bake from Whole Grain Breads) and was intrigued by rye with sunflower seeds. It requires barm. The formula in the book results in 6 cups of barm -- that is a lot! Is it OK to make less, or is there something sacred about the amount? I am not sure how often I would use it.
Also, the recommendation is to use an unsweetened pineapple juice for the first couple of days. Where can you get that? I found some on-line, but it is in a can and I try to avoid cans because their lining leaches toxic chemicals into the food. My preference would be for organic, but conventional would also be OK, as long as it is in glass or plastic that is not polycarbonate. This probably sounds crazy, but I have young kids and try to put as few chemicals as possible in their bodies, even it seems like an uphill battle.
Thank you for your advice on both matters!
