Dissolve baked baking soda in a tablespoon of water to make an alkaline solution, set aside.
Mix all dry ingredients, except corn starch, in a bowl and slowly mix in alkaline solution. It will shape into a very dry dough ball, this is good. It should be hard to shape but not impossible. If the dough is too dry to shape, add a touch of water. If the dough is sticky or wet, add flour.
Using a rolling pin, roll dough into a rectangle with a width of about 4 - 6 inches. Let it rest in the fridge for an hour or so.
Cut the rectangle into 2-inch pieces and run them through your pasta machine, starting with the thickest setting and working your way down. I like it set to the second to the smallest setting (2) but adjust to your desired thickness.
Pass the final sheet of dough through the spaghetti cutter. Dust final noodles with a generous amount of corn starch to keep them from sticking.
To cook: Add ramen to boiling water and cook for 1 -2 minutes. Serve fresh! Cooked ramen won't keep. Uncooked ramen keeps well in the fridge for a week or two.
