Canning Tomatoes
It’s time to can tomatoes. Folks have been canning tomatoes for lengthy sufficient that everybody and their great-grandmother—and I do imply that actually—has sturdy opinions on the way it must be performed. Some people use strictly paste tomatoes, which means solely these varieties developed particularly to be used in home made sauces. Others use any kinds of tomatoes in any respect, from business or conventional to heirloom, in all sizes and shapes.
There isn’t any single right reply in the case of the perfect tomato varieties for canning. The first distinction is that paste sorts often have much less water content material and require much less discount for sauces and ketchup. Style, texture and private desire are elements that matter.
