How to make
Cook the pasta according to the instructions. Drain and set aside.
Blanch the shrimp until they turn pink, if they are not blanched already.
Drain the shrimp.
Pour the olive oil in a pan, and place it on the stove at moderate heat. Add the finely grated onion and crushed garlic, and sauté them for 2-3 minutes.
Add the sour cream, and wine, cook for a couple of minutes until the alcohol from the wine evaporates and stir. Whisk the egg yolks and pour them in the pan. Keep stirring and cook on low heat until the sauce thickens.
Season with salt and black pepper to taste. Add the shrimp and the pasta and leave the pan on the stove until all the ingredients are warm and nicely incorporated.
Sprinkle with basil.
Tips: I used blanched shrimp and graded the onion finely to achieve a smooth texture and flavour.
