(#Vegan #Glutenfree #nixtamalization #buckwheat)Have you noticed that I used the word “buckwheat noodle” instead of “soba noodle”?  You probably also noticed that my buckwheat noodles are significantly yellower than soba. There’s a reason.

Typically, Japanese soba noodles are made from of a mixture of buckwheat and wheat flour. The gluten in wheat flour adds stickiness to the dough so it holds together well.  I only found one brand of a gluten-free version of soba noodles (from Eden Food, Inc.) at my local grocery stores. No doubt, you could certainly substitute these for this recipe.

In this recipe, the darker and smoother buckwheat noodles are made from 100% buckwheat that are treated with limewater, a.k.a calcium hydroxide.  It’s a nixtamalized dough, like masa.  This step dramatically improved the chewy texture, flavor, and aroma of buckwheat.  It also makes the dough stickier and easier to handle when making noodles with a special tool.

To be clear, buckwheat is a kind of seed and is naturally gluten-free.  The “wheat” in the name doesn’t mean it’s related to the wheat family.

This type of buckwheat noodles is very popular in my hometown, Xi’an, China.  If you ever make your way out to see the famous Terracotta Warriors in Xi’an, make sure to stop at a local restaurant and give it a try.  It’s called Heluo (pinyin) in Chinese. However, these nixtamalized buckwheat noodles are well known only in specific areas in northwest China such as Xi’an.

These cold buckwheat noodles taste best when served with the freshly made yellow mustard paste.  It’s super easy to make your own mustard paste for this recipe. All you need to do is pour boiling water over some freshly ground mustard powder (from brown seeds) and let it steep for a few minutes to release all the pungent flavor and aroma.

Although you may not find these nixtamalized buckwheat noodles anywhere here in the US (I got mine from China), you can definitely use any kind of whole grain noodles for this Asian flavor twist.  I’m eager to experiment in making these nixtamalized buckwheat noodles at home. I’ll keep you updated if I have any success. Fingers crossed!
