This easy no-cook jam is made with just three ingredients: frozen raspberries, chia seeds, and a little bit of sugar. It takes 5 minutes of hands-on time. The hardest part is waiting for the raspberries to thaw.

When the frozen fruit thaws, it releases moisture. The chia seeds soak up the liquid and transform the juicy fruit into a jam-like consistency.

How to Make Chia Jam

Stir raspberries and chia seeds together in a bowl.

Chia Jam Variations

Tips for Chia Jam

  • A general rule is to use 1 tablespoon of chia seeds per cup of berries. Adjust according to the juiciness of the fruit or your preference.
  • This jam is not suitable for canning. But it works well as a freezer jam. It will keep in the refrigerator for about 10 days.
  • If you are in a hurry, you can thaw the fruit in a small saucepan over medium-low heat. Stir in the chia seeds and let cool.
  • You can use mashed seasonal fresh fruit instead of frozen fruit.

Advantages of Frozen Fruit

  • You don’t have to wait for the right season.
  • It’s more cost-effective than fresh fruit.
  • You may already have some in your freezer.
  • It’s convenient.
  • Frozen produce is picked when ripe and frozen within hours.
  • Frozen produce can contain more nutrients than produce that’s been shipped long distances and sitting in the store or in your refrigerator for days. Read more in this informative article by Healthline called “Fresh vs Frozen Fruits and Vegetables–Which are Healthier?”

Why Chia Seeds

Here are some reasons to incorporate chia seeds into your diet:

  • They are high in omega-3 fats–an essential fat which we need in our diets for brain and immune health.
  • They are high in fiber.
  • They are high in protein.
  • They are high in antioxidants.
  • They are high in minerals.
  • They are a natural thickener.

Tips:

  • If desired, add 1-2 teaspoons lemon juice to enhance the flavor.
  • If using fresh fruit, mash it with a potato masher before stirring in the chia seeds.
  • If you stir the fruit mixture occasionally while thawing, the chia seeds will thicken faster.
  • The jam will continue to thicken in the refrigerator.
  • As a general rule of thumb, use 1 tablespoon of chia seeds per cup of berries. Adjust according to the juiciness of the fruit or your preference.
  • This jam is not suitable for canning, but it works well as a freezer jam.
