At first, boil crayfish and peel crayfish tails that will be needed to cook the filling.
Fry crayfish shells in the olive oil then crumble them up.
Add chopped onion, carrot, bayleaf, garlic and fry again for 2-3 minutes.
Add wine and set on fire.
After the spirit evaporates and the fire goes out, add tomato paste and 2 liters of water.
Continue boiling at small heat for 2.5-3 hours.
Drain off the boiled mass, add cream and boil for necessary density.
For cooking the filler, whip the butter adding minced garlic and anchovy and pouring in white wine and Dijon mustard.
Put the cooked mass on clingfilm, one spoon at a time, and put the crayfish tails in such way that after rolling the clingfilm you get balls with crayfish tails inside.
Place the balls into refrigerator for a while.
After the balls are cooled cover them plentifully with bread crumbs.
You can place the cooked balls into the freezer.
Fry the balls in oil till golden colour before serving.
