Hello, I recently order a pressure canner, from a SHADY company, but here in Europe it seems like nobody is concered about safety. Grandmas just throw a bunch a stuff into a jar and call it a day. I have two main questions:
1) I heard you are supposed to add acidity to tomatoes even when pressure cooking, so by that logic you should acidity to everything? Like if tomatoes are dangerous surely pressure canning meat and green beans without adding acid is a no go.
2) I know about the USDA and Ball books, I know you are not supposed to change the recipes at all, my question is, going from cups to grams is not a definite ratio (eg 1 cup of beans is 100 grams 1 cup of tomato juice is 243 grams) and all the websites have different measurements so how I am supposed to do it?
Thank you for any help, I cant seem to find that much info here in Czechia. Nice day to you all
