Canning pineapple zucchini is a lovely way to preserve the garden’s abundance in a sweet, surprising way. This recipe turns humble zucchini into something that tastes remarkably like canned pineapple—bright, fruity, and just the right balance of tangy and sweet. It’s a simple water bath canning project that uses basic ingredients: zucchini, canned pineapple juice, lemon juice, and a bit of sugar. The result is a cheerful jar you can use in baking, fruit salads, or even spooned over cottage cheese. If your zucchini plants are producing more than you know what to do with, this is a fun and practical way to put it to good use.
