Spanish toasted ham and cheese sandwich (Bikini)

1. Leave the butter to soften at room temperature.

2. Spread one side of each slice of bread thinly with butter.

3. Turn two slices butter side down, top each with a slice of cheese, two slices of ham and another slice of cheese, and cover with the remaining bread, buttered side out.

4. Heat a frying pan over medium heat, add the sandwiches and press them down lightly with a small pan or spatula.

5. Cook for 2-3 minutes on each side until the bread is golden and crisp and the cheese has melted.

6. Cut diagonally in half and serve hot.

Tip: It's named after the Sala Bikini dance hall in Barcelona, where it was first sold in the 1950s – the secret is the thin, crisp, buttery crust.
