The chia egg, and how chia swells
Chia seeds absorb up to about 10 times their weight in liquid, forming a gel — which is what thickens chia pudding and lets them bind baked goods. A cup of dry seeds weighs about 170 g.
To make a chia egg, stir 1 tablespoon of chia seeds into 3 tablespoons of water and rest 10–15 minutes until it gels; it replaces one egg for binding and moisture (not for leavening).
