I used to buy popcorn in microwave bags. One day, I became nostalgic and bought kernels for stove popping instead. That's how I learned I like homemade popcorn better. It tasted better. I could add my own ingredients. And it was cheaper.
I started wondering what other foods are easy to make and less costly than their ready-made counterparts. I quickly learned that peanut butter can be made in only ten minutes with only three ingredients. And, again, it was tastier and cheaper than its store-bought equivalent. I wanted to find even more items I could make, so I searched for a few books at the library and came up with three good guides.
