Nah. I’m a Purist. I prefer for all of my tomatoes to come in in the heat of end-of-July-into-August so I can complain long and LOUDLY about how BLOODY HOT IT IS TO BE CANNING INDOORS AND I NEED A SUMMER KITCHEN!!
You know - like my Grandma did and her Mother before her, LOL!
Not that any of our Menfolk built Summer Kitchens for any of us. ;)
The summer kitchen is a valid idea for some and some would benefit from simply moving the toaster oven or breadmaker to the porch or garage.
I do the blanching and the final processing outdoors on the back porch, but the actual cooking and jarring of the products happen in the main kitchen. fortunately, I have large fans for the process, and A/C for sleeping.
