柠檬加醋多心酸薄荷加冰多心寒
[níng méng jiā cù duō xīn suān bó hé jiā bīng duō xīn hán]
This means 'Lemon with vinegar makes it more heartrending, mint with ice more sorrowful.' It uses flavors and ingredients metaphorically to describe feeling hurt or having mixed emotions—both bitter and cold, much like heartbreak.
