Rinse the percebes under cold running water to remove any sand or debris.
In a large pot, bring 4 liters of water to a boil.
Add the sea salt and stir to dissolve.
Carefully add the percebes to the boiling salted water.
Cook for about 5-7 minutes, or until the percebes turn a bright reddish color. They should be cooked through but not overcooked.
Using a slotted spoon, remove the percebes from the pot and transfer them to a plate.
In a small skillet, heat the olive oil over medium heat.
Add the minced garlic and cook until fragrant, about 1-2 minutes. Do not let the garlic brown.
Drizzle the garlic oil over the cooked percebes.
Garnish with lemon slices and chopped fresh parsley.
Enjoy your meal!
