The cost of those little active yeast packages in the grocery can be expensive. However, if you go to a warehouse club or a store such as GFS Marketplace, you can buy a bag of yeast so much cheaper. I pick mine up at GFS in a one-pound bag for about $5.00. Each tablespoon in a bag is like one of those little packets in a three-pack of dry yeast at the grocery store that runs about half that price for about three loaves!
So even if you think you'll never use an entire bag, then you're still going to be saving in the long run just by using it a few times. A bag of yeast is usually dated for at least a year. You can make pizzas, buns, sweet dough, etc. in no time with some of the future recipes I'll share with you.
Another suggestion is to split your bag up with a family member or friend. Whichever way you choose, you still will be ahead and able to enjoy real bakery type bread instead of those less filling airy commercial loaves!
