Recently returned from a year teaching English in Korea, my friend Kerissa Barron has been introducing me to some of her favorite dishes, including this one, a spicy cold noodle salad, with lots of toppings.

It's known as bibim guksu in Korean, and if you've ever had bibimbap, it's a lot like that, but chilled, and with thinly sliced raw vegetables and a hard cooked egg. The sauce that holds it all together is sweet and spicy and made with red chili paste, rice vinegar, sugar, and sesame. So good!

I recommend making extra sauce and just keeping some around to dress up leftovers. The meal comes together quickly, the most time needed to cut up the vegetables.

Here's what Kerissa has to say about it:

"Having lived in Korea, where summers are not only hot but extremely humid, when I think summer, I think spicy cold noodles (bibim guksu in Korean). Also, having grown up in a very hot part of California with a mother who literally forbade us to turn on the oven from June until October, I understand the importance of dishes that require little to no cooking to get us through these hottest of months.

However, do not be fooled by the simplicity of preparation. Korean food, and in particular these Korean noodles, are extremely flavorful. Between the red chile paste, sesame oil and rice vinegar these noodles hit all the flavor notes: spicy, sweet, salty, tangy and nutty.

Feel free to use the dressing to make any variety of cool summer dishes. It would make a great salad simply by tossing with lettuce or thinly sliced cucumbers, or even being poured over sliced cold tofu or cooked chicken."

  4. Boil, drain, and cool the noodles:

    Once the water is boiling, add buckwheat noodles, or other type of noodles, and cook according to package instructions, or about six minutes, until al dente. When noodles are finished cooking, pour into a colander and rinse with cold water and drain. To quickly cool your noodles you may also place a few ice cubes in the colander or place the drained noodles into the freezer for a short time, just don't forget them!
