I wrote this post back in the summer of 2010. I basically hated that whole summer but this ginger scallion sauce is one of the few good things I remember from back then.
I still think it's pretty great, and make it often. A bit after reading Francis Lam's article, I saw a similar recipe in the Momofuku cookbook. It's even simpler, just spring onion and ginger and salt and oil, with a small dash of Sherry vinegar. It's good, but I prefer the taste of cooked spring onion. I also find that it's so moreish that if I make a whole big batch that is supposed to keep in the fridge, it disappears in a single meal. And that's a lot of oil for a single meal.
So here's what I do now. I cut up a few spring onions, just the green bits, until I have what I need. I chop or grate some ginger. Put both in a mug with some salt, cover with vegetable oil, not even enough to cover. And give it a minute in the microwave.
This is very fast, I don't need to bring out the machinery, there is no bubbling oil, and the sauce is still terrific. Have it on plain Chinese egg noodles, with a splash of hoisin sauce, as David Chang says in the book, or on anything, really. Best-fast-food-EVER.
