In a marketing stroke of genius, Kraft has jumped on the cocktail bandwagon and come out with cocktails that take a dab of mustard, like the "Grapefruit-ade:" A glass of grapefruit juice with a splash of sparkling rose wine and a dab of mustard (Grey Poupon, please).
Okay, that's barely an alcoholic cocktail. So, how about taking some tequila, beer, and tomato juice, then mixing it with a spoon of gourmet mustard. Shake well then squeeze a bit of lime juice and garnish with a pickle spear. You've just made a Tequila Maria!
Oh the drinks of mustard you'll make! Check out more recipes at Grey Poupon's site.
