Looking for a super simple homemade raspberry jam recipe? Making homemade jam has never been easier.

This Raspberry Jam is made with fresh raspberries, sweet sugar, tart lemon juice.

The key to this easy raspberry jam is when the berries, sugar, and juice get boiling, you’ll speed up the process by thickening it with a cornstarch mixture.

By using the cornstarch mixture, you save hours in cooking, cooling, and canning.

Another quick tip is to cook the cornstarch mixture in the boiling berries for a few minutes until the jam is thick and coats the back of the spatula.

My favorite part about their raspberry jam recipe is that it’s so versatile. You can enjoy this jam in any baked confection like cakes, cupcakes, or cookies. I’ve even put it on toast for a delicious snack!
