Using toasted sesame oil in a cilantro "pesto"? Pesto, chutney, whatever. I go on flavor profile "kicks", right now I am craving Asian - soups, stir fries, curries, you name it.

Here's my thought. I want a simple condiment that I can add to anything (chicken soup for example, homemade or Campbell's condensed, even 40 cent ramen) to give that "kick" that screams 'Asian'. I'm hoping that it will last 2 weeks in my fridge.

Here's my thinking: How about quickly sauteing minced garlic and grated fresh ginger in a tiny amount of neutral oil and letting it cool. Then I whip out the food processor and pretend I'm making classic pesto but with cilantro instead of basil, sesame oil instead of olive?? Maybe I'd add some Thai basil just for fun. Toasted sesame seeds instead of pine nuts? Perhaps roasted peanuts? The big question is the sesame oil. I find it strange that I can't find a single recipe by Googleing. Is there something about one of my favorite ingredients that I am missing? 

Any advice would be appreciated, I'm too broke to experiment randomly.
I actually really like your idea, and will do some experiments next time I can.

Anyway, sesame oil is much too intense a flavor, and way too expensive to use as an oil base for this. Add some for flavor, certainly, but the main oil should be one of the neutral "yellow" oils. Canola/soy/peanut/corn/etc.

Coriander (Cilantro) is definitely the leafy base, but I think you should add some Kaffir Lime leaves too, as they are a part of the distinctive Thai flavor. 

Also, if you can get Galangal, use that instead of ginger, as it is a similar flavor, but more authentic to Thai food.

I would use roast peanuts instead of pine nuts, but only about 2/3 of the amount, as their flavor is stronger.

The last thing would be lime juice, though you shouldn't add that to your condiment but rather add it separately when using the condiment. Adding it to the main jar will cause the whole thing to spoil more quickly, if I'm not mistaken.
