I agree with some of the posts I have read about cooking using bulk purchase foods as THE best way to save money.
I bulk purchase onions at the end of the summer. I love to make onion soup with them. Of course they get added to every thing else too!
I bake a lot of bread so grains, flour and yeast are bought in bulk. I like to buy the add ins by the handful from the bulk barrels in the health food stores. It is a great way to buy just a little when that is ll thaat is needed.
So what are you buying in bulk and how are you using it?
