Bring a pot of salted water to a rolling boil.

Gently lower the shrimp into the boiling water and cook for about 2-3 minutes, until they turn pink and opaque.

Drain the shrimp and let them cool.

In a medium bowl, whisk together the olive oil, apple cider vinegar, lemon juice, smashed garlic, red pepper flakes, Old Bay seasoning, salt, and pepper.

Once the shrimp are cool, toss them in the marinade, ensuring all are coated.

Transfer the mixture to a jar or airtight container and let it marinate in the fridge for at least 4 hours, preferably overnight.

Scoop the shrimp out, letting the excess marinade drip off.

Garnish with fresh herbs before serving.
