Friend: I am making fish tonight and its really plain.
Me: Make a white sauce and add however much cheese you want.
Friend: What’s a white sauce?
Me: Its butter, flour and milk. Melt the butter, whisk in the flour and then add the milk.
Friend: I don’t want a runny sauce.
Me: It will thicken after you add the milk. Then after it’s hot add the cheese and you have a cheese sauce.
Friend: Wait, you can MAKE cheese sauce??
