500 g of brussels sprouts, cleaned
75 g of smoked lard or bacon, sliced
1/2 onion, finely chopped
2 tbsp butter
300 g potatoes
1 egg yolk
nutmeg, salt and pepper
PREPARATION:
Preheat oven to 210C.
Cook brussels sprouts for 10 minutes in boiling water. Meanwhile, peal potatoes and put them to cook about 30 minutes in boiling water.
Cook lard in a pan until golden, then remove and saute onions until tender. Place lard and onions on a paper towel to absorb grease. Once cooked, mash the potatoes. Mix the egg yolk, a bit of butter, the salt, pepper and nutmeg.
In a gratin pan, place half the brussels sprouts, cover with 2/3 of the lard/onion mix. Place the remaining sprouts and finish with lard and onions.
Pour the egg preparation over the brussels sprouts and cover with the mashed potatoes and heat in the oven for 15 minutes.
