SCROLL
Rice-flour udon
undo = to resetFrom wheat, back to rice.
undo — to reset

Return your tired body
to the rice we were made for.

Bread, pasta, ramen — modern meals lean heavily on wheat. undo is a noodle that gently "unwinds" the burden of gluten and additives, returning you to the rice we have always eaten.

To eat is to return.
Reset your body, one bowl at a time.

Possibility of Rice

The hidden potential of rice,
reborn as noodles.

Rice is a staple, a culture, the very landscape of Japan. We select that rice and elevate it into udon. The power of a single grain, in every strand.
