No Barry, no faffing about mixing powder with water. Just dip the knife in Colman's proper English mustard and spread it on the bread, just thick enough to make the eyes water a little :-)
Nice fresh bread,preferably crusty,loads of butter then a nice thick slice of mature cheddar.Throw the pickle in the dust bin and top the sandwhich off with onion and serve with a pint of cold cider.Gods gift to a hungry man.
When I were a lad a healthy lunch was a cheese sandwich with plenty of butter and a glass of milk, followed by rice pudding or similar. I don't think semi-skimmed or skimmed milk was available back then. Lots of carbs and a lot of fat.
One one slice i put butter and then a cheese slice ,then pickle, another cheese slice, and finally put the other slice of bread on top and cut it all in half. Lovely.
