Do you know a source to buy Kansui for making ramen or chinese noodles?

Finding some Kansui is turning into a daunting and elusive task. It's a mixture of alkaline salts that give the springy toothiness to ramen and some other Chinese noodles.

I'm hoping that in the larger cities with huge Asian markets it is available in powder packets.

Has anyone seen it, and if so could you post the store's name and perhaps I can order via mail? It is also sold in a bottled solution, but I'd be more interested in the powder, for shipping concerns.

Kansui is a mix of sodium carbonate and potassium carbonate. Here's a few links that refer to it:

A noodle page (use ctrl f to find "kansui")

A Japanese food suppliers page, with name brand:

  1. If you are trying to make La mian (handpulled noodles) you can subsitue the kansui powder with baking soda since the chemcial compound is similar.

    I use 200g of cake$pastry flour
    2 grams salt
    1 gram of baking soda

    the kneading and dividing takes a lot of practice. I havent succesfully do the whole
    routine yet but I was able to pull some small noodles making some edible noodles.
    my best advice based on my experience is to keep the dough as even as possible and keep an eye of the center of gravity of your dough . fast gentle tugs works well for me and keep them on the table since its easier to pull them that way.

    a good website is

    1. Kansui in liquid form is available in Chinese markets under the Koon Chun brand. It comes in a clear glass bottle labeled "potassium carbonate & sodium bi-carbonate solution" and the UPC is 0-20717-80230-8.

      Do you have a recipe?--because I don't know how how much to use.

        I bought a bottle of this, not sure why, always wonder what it was for but never got around to looking into using it. I'll have to give it a try.
