Pineapple canning recipes are a great way to turn fresh pineapple into sweet, shelf-stable jars you can use for everything from upside-down cake to quick weeknight stir-fries. Canning Pineapple in juice or syrup is really simple, and tastes so much better than store bought. Pineapple Salsa is one of my favorites too. Because pineapple is naturally acidic, most recipes are perfect Water Bath Canning, so you can bring the tropics to your pantry shelf.
