Compound butter

Compound butter

Hello reader,

I thought I’d try making compound butter with my steak tonight. I’ve never made compound butter before, so I started with something simple. A butter made with spring onions and chives. Spring onions are called scallions and green onions in other parts of the world.

As a child, we called them shallots.

I am cooking the eye fillet steak underwater at 55 °C for 2 hours and 10 minutes.

Instructions

Steak

  1. Season the steak with some salt and pepper.
  2. Place the steak into a plastic bag and vacuum seal the bag.
  3. Cook the steak in a water bath for 2 hours at 55 °C.
  4. Remove the bag and open it.
  5. Remove the steak and pat it dry.
  6. Heat a cast-iron pan and sear the steak.
  7. Place a disc of the compound butter on top of the steak. Apply the flame from a butane torch to melt the butter and sear the surface of the steak.
  8. Remove the steak from the cast-iron pan and allow it to rest.
  9. Keep the melted butter in the pan for later.

Butter

  1. Bring the butter to room temperature.
  2. Finely slice the chives and spring onions.
  3. Place the chives and spring onions in a jar and add about 10 mL of whisky.
  4. Infuse the whisky into the herbs using a vacuum chamber and refrigerate the jar for a few hours.
  5. Remove the herbs and put them onto absorbent paper to remove as much moisture as possible.
  6. Put some whole peppercorns and rock salt into a mortar and pound with a pestle until the salt and pepper are coarse grinds.
  7. Process the butter, chives, and springs with the salt and pepper.
  8. Mould the butter in some plastic wrap and refrigerate the butter.
  9. When it’s time to use the butter, cut a disc about 1 cm thick and use it for the steak.

Salad

  1. With a mandolin, slice some fennel, red onion, and radish.
  2. Chop some parsley.
  3. With the back of a cook’s knife, beat the arils out of a pomegranate.
  4. Be careful when you beat the arils out; the juice will spray and splatter, and it may stain your clothes and any bench tops.
  5. Mix a little lime juice and olive oil for a salad dressing.
  6. Toss the salad and season it with some salt to taste.

Plating up

  1. Slice the eye fillet steak with a sharp knife and lay the slices onto a warmed dinner plate.
  2. Spoon some salad next to the meat.
  3. Spoon the butter from the pan over the meat and drizzle a little over the salad.
  4. Give thanks to the Lord.
  5. Eat with a fork; the meat will be tender enough to make a knife redundant.

Concluding thoughts

Today was the first spring day warm enough for shorts and a T-shirt. It was a lovely day outside.

This steak with salad was a fantastic meal for a warm night.
