I really like this recipe of cold sesame noodles from the New York Times:
I follow the recipe except I add more cucumber (preferably Japanese or Persian) and I also add some chopped cilantro and chopped green onion. (I omit the chopped peanuts and much prefer Trader Joe's peanut butter to the Skippy brand -- compare the ingredients.)
The recipe calls for "chili garlic PASTE" and I've looked in a few Chinese grocery stores here in San Francisco. The only one I've found that says "paste" is "fried chili paste", Lee brand. It is way too hot! Instead of 2 teaspoons, I think 1/2 of 1 teaspoon is plenty. Do they mean sauce, instead? I've bought, but not yet tried, "chili garlic sauce" from Lee Kum Kee.
