"Cut a pack of (usually) the Cathedral Extra Mature (which I think both Steve and I like) lengthways in half and I've got what I want for a cheese sauce with the rest to be bagged up as something convenient for sandwiches."

It's fantastic for a lasagne or cheese on toast, or just for a quick cheesy nibble, but just grate it with your grater! You can wash that up in eight seconds!

Incidentally, I must say that I'm not keen on cheddar for a cheese sandwich (heresy, I know...). I much prefer a crumbly Wensleydale or Lancashire, either with slices of slightly salted tomato or with tomato relish. The one that Waitrose sells is a thing of beauty... Incidentally, I regard grated cheese on a sandwich as an abomination. I want it in thin, crumbly slices or not at all...
