Oil and vinegar's truce — stable only if you keep shaking it.

means A dressing made by combining oil and vinegar (or another acid) with seasoning, typically used on salads or cold dishes.

from From French vinaigre, 'vinegar,' itself from vin (wine) plus aigre (sour) — so vinegar is literally 'sour wine.' The '-ette' is a French diminutive suffix, giving 'vinaigrette' the sense of a small, dainty preparation built around that sour wine base. The word entered English in the 1700s, carrying its French kitchen pedigree intact.
