I use all kinds of peppers. Some are sweet, most are hot though. I love having different colors as well. The orange, red and yellows just really make beautiful relish.
Then I package them up in gallon ziplock baggies and put in the freezer. I ended up with 5 of the large bags, then one little quart bag. Also I didn't notice, but the dishtowel I was using has little peppers on it . How fun. Then sometime this winter when it is getting dark early or we have some time to spend inside, I'll either can the relish myself or bring the frozen peppers to a canning party :) I'll probably end up with a few more bags before the the plants completly quit making....
we are still using many of the jalepenos ( they are our favorite) for cooking on a daily basis. I also will freeze a gallon or so of jalepeno pepper slices to use this winter in homeade salsas, pizzas, tacos etc.
