Burger:

1. Heat oil in a deep fryer or a large pot over medium-high heat. The oil should be heated to around 375°F (190°C).
2. Weigh your portion of ground beef and shape into a patty. Season both sides of the patty with salt and pepper.
3. Carefully place the patty into the hot oil using a slotted spoon or tongs. Fry the patty for 3-4 minutes on each side or until it is golden brown and crispy.
4. Use a slotted spoon or tongs to carefully remove the patty from the oil and place it onto a paper towel-lined plate to drain off excess oil.
5. Add a slice of cheese and optionally use a torch to melt the cheese.

Burger Sauce:

1. In a small bowl combine all ingredients. Use a whisk to mix thoroughly.

Assembly:

1. Toast buns. 
2. Spread the sauce on the bottom half of each bun.
3. Add a patty with melted cheese on top.
4. Finish with the top half of the bun.
