Measuring chia seeds by cup and by weight

Chia seeds weigh about 148 g per cup, or about 9 g per tablespoon. They absorb roughly ten times their weight in liquid and turn into a gel, so chia pudding recipes use a small amount, often 2–3 tablespoons per cup of milk. Measure the seeds dry, and stir the pudding twice during the first 10 minutes to stop clumps.
