Last weekend Anders' parents were in town and we took them to Gutta på Haugen to secure the Saturday night dinner. Anders wanted to cook with his dad. Ever since Anders was a kid his favorite meal if he can choose is a juicy piece of meat with Béarnaise sauce. Gutta's Entrecôte is a perfect choice, and we also got some French unsalted butter and goose fat for the potatoes.
200 g per person of high quality entrecôte from Gutta på Haugen
1 tbsp whole black pepper
Sunflower or rapeseed oil and clarified butter
6 small potatoes per person
1/2 jar of goose fat
500g butter, unsalted
2 egg yolks
1 dl white wine
1/2 dl white wine vinegar
fresh tarragon, 1 medium plant
fresh flat-leaf parsley, 1 handful
salt & pepper
Mise en place
Mise en place is usually a good idea, especially for food like this. Place your meat on a cutting board in room temperature. Cut all of the potatoes in two, vertically, to expose as much as possible of the "meat" inside without peeling. Leave potatoes under running water to remove some of the starch. Meanwhile, separate the egg yolks from whites. Keep the whites for something else.
Chop the flat-leaf parsley and put aside. Take 3/4 of the tarragon plant and remove the leaves, chop them finely and put aside. Take the remaining 1/4 and chop the leaves along with the sprigs. Put this aside in a separate bowl where you also put the finely chopped shallot. Measure up the white wine and white wine vinegar in a measurement cup.
Roast the tablespoon of whole black pepper in a frying pan on high temperature. Watch as the pepper corns look like they are popping and jumping around in the pan. Remove from heat and mortar into medium fine pieces. Sift the pepper to remove the finest pieces. Use the medium fine pieces and rub it all into the entrecôte.
Time to cook
We start by making the Béarnaise sauce. Melt the 500g of unsalted butter on low heat in a pot. Once melted, skim off the top layer of milk foam with a spoon. To remove the lower level of milk solids you slowly pour the butter into a new container, leaving behind the milk in the pot. You now have clarified butter. Set aside, but try to keep somewhat warm. Remove 2 tbsp of the clarified butter that you will use for frying the meat later.
In another pot on medium heat; add shallots, 1/4 of the tarragon and the sprigs, white wine, white wine vinegar and 4-5 twists of a pepper mill. Cook until 1 tbsp of liquid remains, then sift through a strainer to remove the herbs and onions. Allow the liquid to cool while you ready a water bath. Bring the water to a boil, then turn off heat completely.
In a glass or stainless steel bowl that can be lowered slightly into the water, add the egg yolks and the concentrated liquid. Start whisking. A big heavy whisk is preferable. You want a good foamy consistency before you start pouring the melted butter very slowly into the mixture. Whisk heavily. Start with a few drops of butter, then add more when you are comfortable. It may take a bit of butter and some time for the temperature of the egg yolks to rise in order for the emulsion process to start properly. As long as you do it slowly it should work out fine. Once all butter is added and you've whisked it together to a thick sauce, add the 3/4 of the chopped tarragon and all the chopped parsley. Add salt to taste. Leave the sauce in the bowl immersed in water to keep it warm, but pay attention to the temperature to make sure the emulsion don't start to break. If it does; quickly add some drops of cold water and whisk heavily.
This can be done simultaneously as you start cooking the potatoes, but the procedures are separated here for a better overview. In a mixture of sunflower/rapeseed oil and clarified butter, on high temperature, fry the meat about 2 minutes on each side to give it a caramelized crust. Wrap in aluminum foil and allow to rest for 10 minutes. Set your oven to 180 degrees C. Cooking time for medium/rare is about 6-8 minutes with the weight and thickness of the meat we used, which was roughly 350g per piece and a thickness of 4 cm. You can also use a cooking thermometer. In such a case you're looking for 52 degrees C at the core before you remove the meat from the oven. It will rise to at least 55 degrees C while cooling. Wrap in aluminum foil and allow to cool for 10-15 minutes or until potatoes are ready.
Goose fat fried potatoes:
Boil the potatoes for 5 minutes in a pot. Remove water, put the pot back on the heat and shake it quite heavily back and forth to dry the potatoes for water and give them a rougher surface. This is important to allow the potatoes to soak the oil. Set your oven to 245 degrees C. In a deep baking tray; pour half the jar of goose fat and distribute it evenly. Place in oven to increase temperature, but pay attention as it starts to give off smoke if you leave it too long. Once warm put the potatoes into the goose fat. Cooking time is roughly 15-20 minutes, but you have to pay attention as all ovens are different. Flip the potatoes around a bit every 5 minute. The last 5 minutes you want to activate the hot air program to really finish off that crispy outside. If done perfectly the potatoes should still be soft inside, while out-of-this-world crispy on the outside. Sprinkle with Maldon salt.
