Makes 6 servings
2 lbs. shrimp, peel on or off
2 tbsp olive oil
1 or 2 grapefruits, zested and maybe juiced
pepper to taste
If you're planning on grilling, skewer the shrimp.
Mix everything together and fridge it for at least an hour, or freeze in a ziptop bag (the pokey parts of shrimp peels/skewers tend to cause problems for the vacusealer, at least for mine). If you're going to freeze, don't add any grapefruit juice, but if you're cooking same-day or next-day, the juice is good too.
