Add berries and water to a small saucepan.

Cook over medium heat, stirring often, for about 5–7 minutes or until the berries have broken down and become jammy.

Stir in a little maple syrup or sugar to taste, or leave it tangy.

Remove from heat and stir in the chia seeds until well combined.

Set the pan aside and let the jam cool for a few minutes. The chia seeds will soak up the liquid and thicken the mixture.

Transfer the jam to a clean glass jar or container, seal, and refrigerate for at least 2 hours or until fully set. Store in the fridge for up to 10 days.
