225g grated, Cheshire cheese
1 tablespoon butter
2 teaspoons Worcestershire sauce
1 level teaspoon dry mustard
2 teaspoons flour
Shake of pepper
4 tablespoons beer (Guiness gives a stronger flavour)
4 slices bread toasted on 1 side only
Put the cheese, butter, Worcestershire sauce, mustard, flour and pepper into a saucepan. Mix well and then add the beer to moisten. Do not make it too wet!!
Stir over a gentle heat until all is melted, and when it is a thickish paste, stop stirring, and swivel it around the saucepan, which it will do quite easily.
Leave to cool a little, and meanwhile toast the bread on one side only. Spread the rarebit over the untoasted side and brown under a hot grill.
This mixture can be made and kept in the refrigerator for several days if required. Sweet white wine can be used instead of beer and gives a good flavour.
