We came across an FDA study from 2012(Opens in a new window) showing that arsenic is naturally found in rice. Washing rice can reduce arsenic by 25-30% (and reducing arsenic is always a good idea). The practice of washing rice is also common in Asian cultures to achieve fluffy rice instead of gummy, sticky rice.
Another good reason to wash your grains? There are hidden bits and particles and other impurities that coat grains when they’re processed and packaged. Like washing your hands, it’s always just a better idea to wash your grains. Certain grains, like quinoa, have a bitter coating that should be washed so they taste better when cooked.
When designing our Grains Colander(Opens in a new window), we tested several hole shapes and structures in order to find a shape and size that would allow water to flow easily through the colander without letting the grains plug up the holes (which would make it a pain to clean up—no thanks). Ultimately we discovered square holes work best since grains won’t get stuck in the holes this way.
A lot of brainstorming and testing went into this design for all of you rice eaters and quinoa eaters and grains enthusiasts everywhere out there.
