Cut large shrimps in their shells along the ridge and extract the esophagus.

Heat olive oil in a large frying pan, throw rosemary and shrimp in it. Fry them from both sides to a characteristic pink color, then add garlic and fry to a characteristic garlic smell. Then splash the wine, chicken broth and put a piece of butter to give the sauce body. Salt, pepper and simmer the shrimp for three to five minutes.
