I know that this post is probably dead but I came across it today when I searched for canning kitchens. I am wanting to put in a small canning kitchen that will also double as a kitchenette for visiting guests. After reading this post and thinking of how I would set up a dream canning kitchen I would put in two stoves with a sink in the middle.
I can grape juice, apple sauce, peaches, pears, tomatoes, cider, and apricots. When I can the tomatoes and the peaches it would be so nice to have a stove on each side of the sink. The one on the left side to have a pot with boiling water to dunk the fruit and have it close enough to the sink to remove fruit and put in cold water bath to remove the skin. And the stove on the right hand side to hold the canning kettles. Also two stoves would come in very handy for making apple sauce, one for cooking the apples and one for canning. Also two stoves would come in handy for canning grape juice.
So my dream kitchen would have a small stove on the left side, a sink in the middle, and a larger stove on the right hand side
