What each ingredient does

Tomatoes
Provide the bulk of the product, and their acidity and moisture set the texture as they soften.

The step that matters

Thoroughly scald the tomatoes. Scalding heats the tomatoes through and softens them enough to be packed well. Thorough heating also helps drive out air and reduce microbes before sealing, which matters for shelf-stable canning.
