First, start by making the Big Mac Style sauce, because it needs at least 4 hours to rest in the refrigerator, or even overnight, to allow the containing aromas to mix well.
For this, place the pickled cucumbers and shallots for the sauce into the mixing bowl of the Thermomix and chop 7 SEC – SPEED 8;
Scrape down the walls of the bowl and add the rest of the ingredients for the sauce;
Mix them well 10 SEC – SPEED 4;
Transfer the sauce into a sealed container and place it into the fridge to rest until 4 hours before serving.This is a Cookidoo recipe adapted to my preferences. Feel free to use the original one if it suits you better. Next, let’s make the homemade brioche burger buns. For this, first you have to clean and rinse the mixing bowl;
Then, grease a large bowl and set aside;
Using the mixing bowl, place the sugar, yeast, milk and water and mix 3 MIN - 37o C (98.6o F) – SPEED 2;
Leave the mixture to rest for 5 minutes;
Add the flour, salt, butter and egg for the brioche buns and knead DOUGH – 10 MIN;
Transfer the dough into the greased bowl and cover it with plastic film or a kitchen textile towel;
Leave the dough to rise for 1 hour;
After that, transfer the dough in a floured surface or a silicone mat and divide the dough into 8-10 pieces;
Using your hands, shape each piece into a ball of dough and place them in a tray covered with baking paper;
Leave the dough balls in the tray for extra 30 minutes to rise;
Meanwhile, preheat the oven at 200o C (392o F);
Beat the egg yolk and the remaining milk and brush the dough balls with this mixture;
Sprinkle sesame seeds or salt on top of the bun;
Place the baking tray into the oven and place a large pot/ tray with water on the bottom of the oven;
Bake the brioche buns like this for 10 minutes;
Remove the container with water and bake the brioche buns for extra 10 minutes using the same temperature; They will get a golden-brown crust;
Transfer onto a wire rack to cool before serving;
Now, let’s ground the meat together with one onion cut into quarters and 2-3 garlic cloves. I also like to add grated carrots to the meat;
Add salt and black pepper according to your taste;
Form 8 balls of meat and cook them on the grill or into a grill pan;
Using a grill spatula, smash the meat balls and cook them for 5-7 minutes on each side;
Place a cheese slice on the meat to allow it to melt while grilling;
Now, create your unique big mac smash burger by starting with the brioche bun. Add the meat, the sauce and the rest of the ingredients for filling the burger;
Serve warm with roasted potatoes.
