A quick and easy overnight rhubarb chia seed jam that is tangy, sweet, and perfect for spreading on sourdough toast. This jam uses simple ingredients and requires minimal hands-on time.
Let the rhubarb mixture cool before adding chia seeds to avoid clumping. Stir frequently while cooking rhubarb to prevent burning. Jam can be ready in 2 hours at room temperature but thickens best overnight. Store in airtight container in fridge up to 7 days or freeze up to 3 months.
