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.
