“What exactly is rice-flour udon?” “How is it different from wheat udon?” This article answers those questions. Rice-flour udon is a noodle that gives you another option on days when your diet leans heavily on wheat. Here we explain the basics of rice-flour udon, how it differs from wheat udon, the appeal of going gluten-free, and the best ways to enjoy it.
What Is Rice-Flour Udon?
Rice-flour udon is udon made primarily from rice flour, produced by finely milling rice (non-glutinous rice). While ordinary udon is made from wheat flour, rice-flour udon uses no wheat at all. The rice-flour udon from undo, the rice-flour udon noodle maker, is made with rice flour from non-glutinous rice grown in Hiroshima Prefecture and is finished to be additive-free and gluten-free.
How It Differs from Wheat Udon
The biggest differences are the ingredients and whether or not gluten is present. Gluten, a protein found in wheat, gives dough its elasticity and chewy bite, but rice-flour udon contains no gluten.
- Main ingredient: Wheat udon uses wheat flour; undo’s rice-flour udon uses rice flour from Hiroshima-grown non-glutinous rice.
- Gluten: Present in wheat udon; absent (gluten-free) in rice-flour udon.
- Texture: Wheat udon has a firm, springy bite; rice-flour udon is smooth and pleasantly chewy.
- Additives: These vary by product for wheat udon; undo’s rice-flour udon is additive-free.
Because rice-flour udon softens quickly, the most delicious way to enjoy it is fresh out of the pot.
Why People Choose Gluten-Free, Additive-Free Rice-Flour Udon
Gluten is a protein found in grains such as wheat and barley. Because rice-flour udon uses no wheat, it can be an option for people who want to cut back on wheat and for those with a wheat allergy or gluten intolerance. undo is also committed to being additive-free, valuing the natural taste of the rice itself.
If you have allergies, please check the ingredient list on the product just to be safe, and consult a physician if necessary. For more, see our frequently asked questions.
The Best Ways to Enjoy Rice-Flour Udon
Boil the noodles in plenty of water for the time on the package, then chill them well in cold water to bring out their smooth, springy texture. For warm udon in broth, we recommend pairing it with our gluten-free “ando no dashi”. You can enjoy it just like wheat udon, in kamatama, bukkake, or warm udon style.
