Ingredients

Frozen raspberries
Granulated sugar
Grapefruit, lemon, lime, or orange
Cornstarch
Water

See recipe card for quantities.

Instructions

Pour frozen raspberries, granulated sugar, and citrus juice into a microwave-safe bowl.

In a separate bowl, combine water and cornstarch. Stir to combine. Mixing the cornstarch water first helps the corn starch to completely mix in.

Pour the cornstarch and water mixture into the frozen raspberry mixture and stir to combine.

Microwave the mixture on high for five minutes.
Carefully remove the bowl from the microwave and stir. The consistency should be thick like jam.
Enjoy hot or cold.

Hint: Do not just toss the cornstarch into the raspberry mixture or you'll get little cornstarch clumps in the sauce. Mixing the cornstarch water first helps the corn starch to completely mix in. I like to use this mini whisk to ensure the mixture is combined.

Substitutions

Frozen raspberries - instead of frozen raspberries, you can use fresh raspberries.
Granulated Sugar - cut the sugar down to one tablespoon for a sour, low-sugar sauce.
Citrus - you can choose any citrus you have on hand.

Variations

Low sugar - decrease the sugar to one tablespoon for a low sugar option. You can also replace the sugar with a tablespoon of honey or agave.
Blueberry sauce - use frozen blueberries instead of frozen raspberries.
Seedless raspberry sauce - after taking the sauce out of the microwave, pour it into a mesh strainer placed over a large bowl. Then, gently press the sauce through the mesh strainer until all the seeds are filtered out.
