By popular request, and courtesy of A A Gill's Ivy cookbook---

150 g Cheddar chees, grated.
3 medium egg yolks
1 tbsp Worcestershire sauce
1 tsp English mustard
6 drops Tabasco sauce
30 ml Guiness (not very much so you have to drink the rest, an added bonus!)
8 slices bread - a smaller bloomer loaf is ideal
salt and pepper.

Mix together all the ingredients except the bread, and season to taste. Toast the bread on both sides, spread the cheese mixture on top, abnout 1 cm thick and grill until browned. Delicious!
