THE BUTTER BURGER RECIPES

Steps:

• For the compound butter: Stir together the butter, basil, parsley, tarragon, cayenne and garlic; season with salt and pepper. Spoon the mixture onto a piece of plastic wrap in a 6-inch-long mound. Fold the plastic wrap over the mixture to enclose it, and roll it to form a log about 2 1/2 inches in diameter. Chill until firm, about 2 hours.
• For the roasted garlic aioli: Blend the mayonnaise, lime juice, paprika, cayenne, cumin and garlic in a food processor until smooth.
• For the burgers: Preheat the oven to broil.
• Form the ground beef into 4 patties. Stuff a slice of the compound butter inside each and broil the burgers to the desired doneness. Add another slice of the butter to the top of each burger, followed by a slice of cheese. Broil briefly, just until the cheese melts.
• Serve on buns with a small mound of the aioli on top of the cheese. 

Steps:

• Put the milk, butter and 100ml water in a pan and gently heat until the butter is melted. Set aside to cool until just warm.
• Tip the flour, sugar, yeast and 1 tsp salt into a large bowl and gradually work in the milk mixture, then the egg, until you have a smooth dough. Tip the dough onto a floured surface or into a stand mixer fitted with a dough hook and knead until elastic and shiny. Divide into 12 (about 80g each) pieces and roll into tight balls. Transfer to baking trays lined with baking parchment, leaving plenty of space between them, and put in a warm place to prove for 30-45 mins.
• Heat oven to 200C/180C fan/gas 6. Press the rolls down gently using your hands, then brush over some milk and scatter over the sesame seeds, if you like (or, dust with some flour). Bake for 10-12 mins until risen and lightly golden. Leave to cool completely, then serve. Make up to two days ahead and keep in an airtight container.
