(Poro, tuétano y escamoles)

Serves 4

Ingredients for bone marrow confit

1/2 beef marrowbone
Ingredients for roasted leek
1 leek
2 tbsp bone marrow confit
3 tbsp bone marrow fat
1 leek green (about 4 inches/10 cm long), cut into 8 thin strips

Ingredients for bone marrow mayonnaise

1/4 cup bone marrow
2 tbsp fresh key lime juice
1 tsp kosher salt

Ingredients for escamoles

1/4 white onion, brunoised
1 large garlic clove, brunoised
1 tsp olive oil
1/2 chile serrano, brunoised
1/4 cup (30 g) escamoles
6 epazote leaves, thinly sliced
1 tsp kosher salt

Ingredients for plating

Olive oil
1 chile serrano, thinly sliced
20 epazote sprouts

Method for bone marrow confit

Scoop out the bone marrow, place in a small pan, and heat over medium heat until it melts and browns. Remove from the heat.

Method for roasted leek

Cut the leek crosswise, separating the green part from the white part. Set the green part aside; char the white part, and then remove the outer layer and discard. Cut the white part in half lengthwise and then halve each of those pieces crosswise.

Place the leek pieces, along with the bone marrow confit and fat, in a vacuum-sealed bag.

Cook in 1 cup (about 250 ml) 176°F (80°C) water at for 25 minutes. Cool and remove from the bag; set aside.

Slice the green part of the leek lengthwise into ribbons and blanch in boiling water.

Drain, cool, and use the leek ribbons to tie the leek pieces cooked with the marrow.

Method for bone marrow mayonnaise

Scoop out the bone marrow, place in a pan, and heat over medium heat to 104°F (40°C), until it melts and browns.

Drain the fat and pour into a bowl; whisk in the lime juice to emulsify.

Adjust the salt and place in a pastry bag or squeeze bottle.

Method for escamoles

Sauté the onion and garlic in the oil in a pan over medium heat. Add the chile, then add the escamoles.

Stir gently, being careful not to burst them, then add the epazote and adjust the salt.

Remove from the heat.

Plating

Heat the oil in a pan and caramelize the roasted leeks on the convex side. Place the leeks on a baking sheet and cook in a 350°F (180°C/Gas Mark 4) oven for 3 minutes.

Place each leek on a plate, open side up, and spread some of the marrow mayonnaise on top of it.

Arrange 2 tablespoons escamoles over the mayonnaise on each leek and finish with the chile slices and epazote sprouts.
