I also refer canning BUT not in the summer heat. When I was feeding our while family of 6 from our old garden (terrific soil) and fruit trees as well as running a small boutique jam, jelly, and pickle business out of my garden we had no AC. Often I stayed up most of the night after it cooled off a bit just to keep the pressure and water bath canner going. I prefer to freeze tomatoes and berries and can them in the winter when it is cold.
We have 2 large freezers but buying new canning jars isn't cheap anymore. Up in Washington I was making blackberry and mulberry jelly and blueberry jam. I had to buy more half pint jars and the price even at Costco made my eyes pop. The following year DH wanted to know why I was packing cartons of empty canning jars to take on our trip! LOL I have gotten rid of some of the jars but still have boxes of empty ones packed away in my shed. They are one of the things I will be taking when we move to Texas! LOL Along with the 2 pressure canners, the water bath canners, and all my canning equipment. I used to can my goat milk for the calves when I ran out of freezer space in my 3rd freezer. We ended up giving that small freezer to DD1 when we remodeled the garage into a bedroom, entry and large utility room.
Actually with the last heat wave, we were warned about losing power. Luckily we have LADWP which doesn't do rolling blackouts so they would repair the power asap. I talked to DH about buying a generator, He said we had one in our 5th wheel trailer but I told him we needed one large enough to carry both house freezers and some other stuff. The generator in the trailer will work the microwave, coffeemaker, and trailer AC but that is it. I don't want to lose 2 freezers full of meat. DH agreed that we should probably have a large one. We will definitely get one when we move to a ranch.
Luckily the heat has broken and is cooling off a bit at night, Still hot though.
Everyone stay safe during the bad weather.
