Chia seeds are tiny black or white seeds from the chia plant, prized for their ability to soak up liquid and form a gel. One metric cup (250 ml) of chia seeds weighs around 170 grams or 6 ounces. They're used whole in puddings, smoothies, and baked goods, and as a vegan egg substitute when stirred into water.

Chia seeds are usually measured in tablespoons or grams rather than cups, and small amounts make a big difference in how a recipe sets. Weighing in grams gives the most reliable results across recipes.

Ground flaxseed is the other go-to seed for vegan egg replacements. Both form a gel when stirred with water, but flaxseed is lighter (113 g per cup vs 170 g for chia) and gives a slightly nuttier flavour. You can swap them 1:1 by tablespoon, though chia produces a thicker, more neutral-tasting gel. See our Ground Flaxseed converter.
