Cheesy sauce

My cousins friend showed me how to do this when I went to her house, it's really simple and really nice. It works well with fish and as the sauce on top on lasagna but I'm sure you'll think of many other uses. Sorry I don't have the measurements as when we made this we weren't following a recipe.

Ingredients

Butter (the stuff you get in a packet don't use spreadable)
Flour (any type, one time we used brown self raising flour!)
Milk
Cheese (we used cheddar but you could experiment with different types)

Method

1. Grate the cheese
2. Put the pan on the hob at a low heat
3. Add a bit of butter it doesn't really matter how much (well it depends how much sauce you want)
4. Heat and stir until it has all melted don't let it boil, if it starts bubbling then take it off occasionally 
5. Add a bit of milk and stir, then add flour (it may look a bit brown when adding the flour but don't worry!) keep doing this until you feel you have enough sauce and it has a nice consistency (remember the cheese will also make it less runny)
6. Without taking it off the heat add the cheese which you should of already prepared
7. Stir well so the cheese mixes in (if it looks a bit runny don't worry!, it will soon harden don't add more flour, if it is a bit hard that's fine too but don't add anything else after the cheese)
8. Dip a spoon in and try a bit to check it's OK.
9. Enjoy!
