Homemade Big Mac-Style Double Burger

Make the sauce by thoroughly mixing all its ingredients.

Divide the mince into 8 small balls. Place each on a can approximately the diameter of a sesame bun.

Turn onto baking paper and press firmly to shape each into a thin burger.

Arrange the burgers on a tray and refrigerate.

Halve 4 buns. Cut the bottom third, about half a finger thick, from each remaining bun to make the middle bread layers.

Heat a griddle or frying pan and toast the bread.

Cook the burgers on a lightly oiled griddle or pan for 2 minutes per side. Season with salt as they cook.

Spread sauce on each toasted bun base and add a little onion.

Add iceberg and a cheese slice. Spread sauce on each middle bread layer, then add onion, iceberg and 3 pickle slices.

Place a cooked burger on each base and each middle layer.

Stack the middle layer onto the base and cover with the bun top. Press gently and microwave for 15 seconds. Serve in a box or on a plate.
