Butter and soy sauce is a combination Japanese cooks figured out long ago. Wafu pasta (Japanese-style pasta) uses it all the time, and this garlicky version is the one you'll make at midnight.
It's simple: spaghetti, lots of garlic sizzled in butter, then soy sauce and a little oyster sauce, loosened with starchy pasta water into a glossy sauce. Black pepper and nori finish it off.
Throw in mushrooms, bacon or a soft egg if you've got them, but it's great just as it is.
