Step 1

Cut the centre out of a slice of bread, leaving only the thin crust in one piece - then cut that centre into smaller squares.

Step 2

Place all of the bread along with another regular full slice on a baking tray and lightly toast under a grill for a few minutes.

Step 3

Melt the butter in a pot on a medium-low heat, then add the cheese. Stir it all in until everything is melted.

Step 4

Gradually add the beer bit by bit, stirring until combined before adding the next bit of beer.

Step 5

Stir in the mustard and Worcestershire sauce and remove from the heat.

Step 6

Stack the hollowed out crust of the bread onto the full slice and drop in half of the small squares.

Step 7

Fill this with the cheese mixture, then top with whatever squares you have left over.

Step 8

Put it under the grill for another 1 or 2 minutes until the bread has fully toasted and the cheese mixture is slightly brown.

Step 9

Enjoy!
