In a wide deep skillet or wok over medium heat, melt butter. Let it cook until amber and nutty smelling, 3–4 minutes. Watch it closely and avoid burning the butter.
Add all minced garlic at once. Cook over medium, stirring constantly, 2–3 minutes until deeply golden and sweet smelling.
Add soy sauce, dark soy sauce, oyster sauce, fish sauce, sesame oil, sugar, scallions and rice vinegar. It'll sizzle hard.
