Into a bowl, start by adding the shrimp, season with salt, black pepper, sweet paprika, oregano, and add the wheat flour. Mix it all together very well so that these spices are incorporated into the shrimp.
Into a skillet, add the olive oil or oil and evenly spread it along the bottom. Add the butter and stir well until melted, add the garlic and cook until golden.
Once you've done that, transfer the shrimp to the skillet and stir again for 3 minutes.
Cover the pan and let it cook for another 3 minutes.
After this time, add the milk and mix. Cover the skillet again and let it cook for another 10 minutes. Let it cook until almost all the milk has dried up.
Serve.
