Peanut Sauce
http://rebeccmeister.livejournal.com/80802.html

1/2 cup canola oil
1/4 cup toasted sesame oil
1 cup finely chopped yellow onions
1/8 cup finely minced garlic (12 cloves; I just used a whole head)
1/4 cup red wine vinegar
1 cup water
3 tablespoons sugar
1/4 cup ketchup
1/2 cup creamy peanut butter (I used 1/2 cup freshly ground peanut butter, but it wasn't peanutty enough, so I added an additional 1/2 cup Jiffy--thanks, E)
1/2 cup fresh cilantro leaves
1/4 cup tamari
2 1/2 tablespoons lime juice
1 teaspoon hot pepper sauce, or to taste (I used a non-Tabasco variety that has less vinegar in it)

All you do is heat the canola and sesame oils in a large pan over medium heat; add the onions and garlic and simmer for 5 minutes; and then add the remaining ingredients and simmer uncovered for 5 minutes. Then puree the mixture in a blender or food processor until smooth. 

Warning: This makes a TON of peanut sauce, which is great if you're a peanut sauce addict, like yours truly. It will keep for up to two weeks in the refrigerator. But if you want to make just a bit to impress your friends, make a half recipe.
