Using fresh yeast
Yeast keeps in the freezer pretty well, so you're probably good for at least a year. If you cultivate the habit of doing pizza from scratch instead of buying it, or making your own tortillas, or doing soup with homemade bread a couple of times a month, you'll make your way through it. My favorite bread recipe is: Mix 1.5 cups flour, 1/3 cup oil, 1/3 cup sugar, 1 cup water. Let sit for 20-30 minutes. Add 1 tsp salt and 1.5 cups whole wheat flour. Kneed until it forms a smooth ball (adjusting flour or water as needed). Let sit for 2 hours or until you get around to it. Shape into buns. Let sit for 30 minutes or more. Bake @ 350 for 20 minutes.
I didn't know you could buy fresh yeast in one pound quantities. I always liked using small cubes of it in baking. You don't see those in the grocery store these days. At least not where I've been looking.
The stuff I remember had that funny texture - you rubbed it between your fingers into the bowl of water and sugar. I always enjoyed that little step. And it smelled so good!
