When you buy Hatch chilies, there are mild, medium hot and hot
so you generally have a choice of heat or not. I usually buy about fifteen pounds for our family of two. Today I bought ten pounds because I still have 2 large bags of mild, and one bag of hot left. You can put them in so many dishes, anything Mexican, Tex-Mex, soups, bean dishes, braised meat dishes, chicken dishes, egg dishes.
Hubby blackens them on the grill and brings them into me. I let cool, for a bit, then pack 4 to 5 peppers into a quart size zip lock. Then I put about 4 to 5 of those bags into a gallon size freezer zip lock and store them in the freezer stacked. When I want to use them, I take out what I want, let them sit for about ten minutes, then remove the blackened skin and pull out the stem....seeds usually come out with the stem.
How many you pack into the quart size bag depends on how big your peppers are. Last year, the crop was huge. When you buy them, pick out as many perfectly straight ones as you can. The blacken quicker and easier that way, and are easier to pack.
