Aguja de ternera al sous vide

Ingredientes

• 1 chuck steak (about 1 1/2 to 2 pounds (can also use 2 smaller steaks))
• 1-2 teaspoons salt (depending on size of steak(s))
• 1/4 teaspoons black pepper
• 1 tablespoon oil (high smoked point for searing)
• 4 tablespoons unsalted butter
• 1 shallot (minced)
• 1 sprig fresh thyme
• 8 ounces sliced white mushrooms
• 1/2 cup brandy
• 1 tablespoon Worcestershire sauce
• 1/4 teaspoon black pepper
• 1 tablespoon gochujang
• reserved bag sauce from chuck steak
• 1/2 cup beef stock
• 1/2 cup heavy cream
• Salt (to taste - I did not need to add any)

Preparación

1. 1

   Heat a sous vide water bath to 130F degrees.

2. 2

   Season the steak(s) with salt and pepper and seal them in a vacuum seal bag.

3. 3

   Cook for 36 hours in the water bath.

4. 4

   Remove and place steaks on a plate, reserving the bag sauce to make the mushroom gravy. Thoroughly pat them dry so the outside is very dry.

5. 5

   if not serving right away, place the bag in an ice bath for 10 minutes after removing from the water bath. Store in the fridge or freezer until ready to use.

6. 6

   Heat oil in a cast iron skillet over high heat until smoking.

7. 7

   Add the steak and brown for 30-60 seconds on each side. Remove and serve with mushroom gravy.

9. 9

   Heat the butter in a skillet and add the shallots, thyme and mushrooms. Sauté about 5-7 minutes, or until mushrooms have lost much of their liquid and pan starts to dry out.

10. 10

    Add the brandy and cook for 3-5 minutes, until most of it has cooked off.

11. 11

    Add all the remaining ingredients (except the heavy cream) and bring to a simmer. Cook for 2-3 minutes.

12. 12

    Add the cream and simmer for about 3-5 minutes, until thickened slightly. If it is still too thin, keep cooking until it is thick enough to coat the back of a spoon.

13. 13

    Add additional salt if needed, then serve over chuck steak.
