Method

1. 1

   The night before, warm the milk, butter and molasses together until the butter melts, cool slightly, then add the cold water and 1 egg. Mix the flour, salt and yeast in a large bowl, stir in the liquid to a rough dough, cover with a damp towel and refrigerate overnight.

2. 2

   In the morning, turn the dough out onto a floured surface, knead it briefly and divide it into 8 balls. Set them on a lined baking sheet, cover and let rise for about 1 hour, until doubled.

3. 3

   While the buns rise, slice the onions and cook them in a little butter over medium-low heat, stirring now and then, for 10 to 15 minutes until golden and sweet.

4. 4

   Heat the oven to 425°F. Brush the buns with a little milk, sprinkle with sesame seeds if you like and bake for 15 to 20 minutes, until golden. Cool on a rack.

5. 5

   Rub the steaks with the cut garlic and season with salt and pepper. Sear them in a very hot skillet or grill pan for 1 to 2 minutes a side, then rest them on a plate.

6. 6

   In the same pan over medium heat, fry the bacon for 5 to 6 minutes until crisp. Fry the eggs in the bacon fat, in batches, for 2 to 3 minutes until the whites are set.

7. 7

   Split the buns and toast the cut sides in the hot pan for about a minute.

8. 8

   Spread mustard on each bottom half and layer on the steak, ham, cheese, bacon, tomato and lettuce. Top with a fried egg, a generous spoon of chimichurri and the caramelized onions, then the lid.
