Like pound cake, three teacup chicken refers to the "small Chinese teacup," which is used to "measure the soy sauce, vinegar, and sugar." At least that's what Grace Young and Alan Richardson claim for this rendition in The Breath of a Wok. Cute anecdote aside, what's amazing is how simple this sauce is to make. It's tart, sweet, astonishingly complex. Plus it comes together in a matter of seconds, and pairs nicely with the chicken.
