• .5 kg lean-ground beef
• .5 kg ground pork
• 2 tbsp Dijon mustard
• 3 tbsp Worcestershire
• 2 tsp onion powder
• 2 tbsp chopped thyme
• 1 tsp salt
• 1 tsp freshly cracked pepper
• 2 tbsp grapeseed oil (for frying)
• 1 small loaf of French bread,

• 1 clove garlic, peeled
• 1 tbsp olive oil (for seasoning the bread)
• 4 slices Gruyere cheese
• 4 slices fontina cheese
• Caramelized onions
  (see Balsamic-Caramelized Onions recipe)

In a large mixing bowl, combine the ground beef, ground pork, mustard, Worcestershire, onion powder, thyme, salt and pepper. Gently mix until combined, and then form into patties. Set your oven to broil.

Add the grapeseed oil to a large frying pan, and heat it to medium-high. Add the patties, and let them cook for 4 minutes before flipping. Reduce the heat to medium and let the second side cook slowly until the burger is cooked all the way through. Top the hot burgers with slices of Gruyere and fontina, and transfer them to a cutting board to rest.

Toast your French bread slices (2 per burger) on each side under the broiler. Slice your garlic clove in half, and rub the cut side on the toasted bread. Brush the toast with olive oil, and season with salt to taste. Assemble your burger between 2 slices, beginning and ending with caramelized onions. Dig in.
