I don't know if it's better buying things in bulk. It seems like it ought to be. Buying in bulk and making bread go together because they're both old- fashioned. Buying in bulk. The why becomes plain when you mix the dry and wet ingredients together, knead the dough and the yeast starts to work its magic.
Bread is alive.
One of life's keenest pleasures is watching bread rise after you've put it in front of a fire, or on top of a heat grate or a warm oven. All is quiet. The fire crackles, shifts, settles and glows and the dough expands slowly like your good fortune. Yes, your good fortune. After letting the bread rise for an hour and a half, punching it down, adding the soft wheat berries and letting it rise again, you are darn lucky.
