how do I safely experiment with recipes?
I've been a home canner for several years using recipes from books and websites. I want to start experimenting with my own recipes, but how can I make sure I'm doing this safely? Does anyone have any advice or know of any sources I can reference to make sure my sugar/salt/acid to fruit/vegetable ratio is what it needs to be when I'm experimenting with different fruit and veggie combinations?
Additionally, I'd like to start experiementing with adding different herbs, spices, and even nuts to my canning recipes, but I'm unsure how to go about this. I know some herbs will not store well long term, so I'd like to infuse them somehow. I'm also curious how nuts and seeds will hold up with canned fruit over time. Does anyone have any advice?
