Duck breast fillets with spinach & lacquered sauce with ginger

For ➍
2.2 dl fresh brown veal stock
2 tbs soy sauce
4 shredded ginger balls in syrup
2 large duck breast fillets
900 g spinach
2 shallots
2 garlic cloves
4 tbs roasted peanuts

Preheat the oven to 180°C. Put the veal stock, the soy sauce, the ginger syrup and the shredded ginger balls in a saucepan. Reduce to half over low heat.
Finely chop the shallots, rinse the spinach, peel and press the cloves of garlic. Coarsely chop the peanuts. Keep apart.
Make diamond-shaped notches in the skin of the duck breast fillets with a sharp knife. Bake the skin side golden brown on a high heat, in a frying pan without fat, and then the other side*. Slide the duck breast fillets into the oven for another 25 m to continue cooking**. Turn the fillets over, place them on a cutting board, cover them with aluminum foil and let them rest for 5 m.
Pour 4 tbs of the released cooking fat into a sauté pan. Add the spinach, shallots and garlic. Shrink the spinach over a medium heat. Season with pepper and salt.

Slice the duck breast fillets. Serve with the spinach and the sauce. Sprinkle with peanuts and add pommes of dauphine or potato quenelles.

*Avoid splashing and pour the released cooking fat into a bowl before frying the other side of the duck breast fillets until golden brown.
**Or continue to bake in the pan until done.
