STEP 1/19
Prepare the egg yolk separately as 1 for sauce and 1 for patty.
STEP 2/19
Chop shallots into small pieces,
STEP 3/19
Slice the onions thickly. You can use white onions. I used red onions.
STEP 4/19
Dissolve 100g unsalted butter in a medium-hot water. It's safe to use medium heat.
STEP 5/19
When butter melts, white impurities form. Take it out with a spoon. You can turn off the light now.
STEP 6/19
Now pour the purified butter into a clean container except for the lactose that has sunk underneath.
STEP 7/19
Put egg yolk and 2 tablespoons of water in a pot with thick bottom.
STEP 8/19
Mix gently over low heat, stirring with a whisk. Keep it on low heat so it doesn't burn.When the concentration is thick enough, put it on your finger and blow it out.
STEP 9/19
Remove from heat and mix, adding a small amount of refined butter. Add purified butter after all absorption. If you put in all the refined butter at once, it won't mix.
STEP 10/19
Combine chopped shallots, hand mashed whole pepper, dry white wine and white vinegar in a pot.
STEP 11/19
It's supposed to boil down to just a little bit of soup, but since it's hamburger sauce, I boiled it down to make it as dry as possible.
STEP 12/19
Lastly, add tarragon that smells really good and mix it well.
STEP 13/19
Put it in the Sabayong that you made before and mix it well.
STEP 14/19
Mix the egg yolk, beef, salt, and pepper and mix them together to complete the patty with a thickness of less than 3cm.
STEP 15/19
Melt the butter in a pan and toast the burger bread at medium temperature. At the same time, I start baking onions and caramelize them.
STEP 16/19
Bake beef patties over medium heat. Turn the meat over, turn the onions over and cook, and remove from the heat when the onions are brown and mushy to some extent.
STEP 17/19
Place cheese on top of cooked meat and melt it indirectly. If you stack them in order, hamburgers are done!
STEP 18/19
Put plenty of sauce on the bread and fix it with salad. Cover with onion, sauce, patty, and bread with sauce and that's it.

*Chef Michelin adds: If you make it in advance, preheat the oven to 180 degrees, heat it for 5 to 6 minutes, and eat it.
The hamburger is cooked thanks to the luxurious French vearne sauce. It's a healthy homemade burger made from good ingredients.
