[ICTHUS]

You will need:

1 can (400 mL, more or less depending on how thick you want your sauce) coconut milk
2 tbsp fish sauce (or more if you're feeling adventurous)
2/3rds of a cup of good (please, if you can, get it with no preservatives, no emulsifiers, and no added sugar) chunky peanut butter
1 tbsp (or more to taste) red chili paste
1 tbsp curry powder
2 cloves garlic
1 tsp freshly-grated ginger
1 lime wedge
2 packages of udon or, preferably, hokkien noodles

Combine everything except the lime wedge in a blender, squeeze the lime juice into the blender and throw out the lime. Blend until smooth. Fry one (or two if you want 'drier' noodles with less sauce) package of noodles until slightly cooked, meanwhile (if you wish) stir in some greens, such as snow peas or bok choi lettuce, and some cooked chicken, beef, lamb, tofu, or seafood. Add the sauce, and simmer for about 10-15 minutes, until sauce begins to reduce and noodle mixture is heated thoroughly.

I use Adams brand peanut butter for this recipe. It isn't ridiculously expensive (about $3.50 CAD for a jar that I get about 2 or 3 of these recipes out of) and the ingredients list reads "Peanuts, salt". =)
