I can, can you? Sure you can! Canning is not hard to do at all, especially if you pick a really easy project like canning fruit. This year I received a box of luscious peaches from Washington state. They were perfectly ripe, but a bit crushed in spots due to poor handling in transit. Instead of canning slices or halves, I used the fruit—some perfect and some not so perfect—to make peach ketchup!
Peach ketchup is a lovely peachy color, but it tastes very much like tomato ketchup. Taste it before you can it, and adjust the spices and sugar to suit yourself. Use really great tasting fruit, it should not be brown or overripe, but if it is soft in spots, that's ok. Use the tangy sweet and sour ketchup just as you would regular tomato ketchup. It’s particularly great on potatoes.
