Why does my quinoa taste bitter?

It's likely the saponins (a natural coating). Even if the box says 'pre-washed', rinsing your weighed quinoa in a fine-mesh sieve until the water runs clear removes bitterness.

Quinoa (Dry)

Quinoa seeds are small and spherical, packing densely with very little air space compared to flakes. Like rice, it expands about 3x when cooked. Precise dry measurement is vital not just for portioning, but to calibrate the cooking water exactly so it doesn't turn into mush.

Grains

Rice, oats, quinoa, couscous and similar grains hydrate based on precise ratios. Volume is skewed by kernel size and air gaps. Weighing both dry and cooked grains keeps texture predictable.

Why weigh dry grains?Cup measures change with grain size and packing. Weight guarantees the right water ratio for fluffy, non-gummy results.
