The cooking time for boiling frozen shrimp will depend on the size of the shrimp. As a general rule, you should boil frozen shrimp for 2 to 3 minutes, or until they turn pink and opaque.

Here's a step-by-step guide on how to boil frozen shrimp:

  1. Fill a large pot with enough water to cover the shrimp.

  2. Add a pinch of salt to the water and bring it to a boil.

  3. Add the frozen shrimp to the pot, making sure they are fully submerged.

  4. Stir the shrimp occasionally as they cook.

  5. Boil the shrimp for 2 to 3 minutes, or until they are pink and opaque.

  6. Use a slotted spoon or strainer to remove the shrimp from the pot.

  7. Drain the shrimp and rinse them under cold water to stop the cooking process.

Once your shrimp are cooked, they are ready to be eaten or used in your favorite recipe.
