This simple sauce goes well with spring rolls as a dipping sauce. Also, it makes a good marinade for seafood. I once served grilled trout marinated in this sauce to a friend who disliked fish—it completely changed his mind!
Note
Sesame seeds can be purchased already toasted, but to toast your own, preheat the oven to 350°F (177°C). Spread the sesame seeds out on a baking sheet in a single layer. Bake for 5 to 6 minutes, or until the sesame seeds are crisp and fragrant. Watch them carefully so they don't burn.
