Is there a way to make a generic cheese sauce?
'Cheese sauce' is really anything semi-liquid that tastes a bit like cheese &amp; can be poured or dipped, depending on how liquid.
Some fast ideas:-
Camembert, brie etc - put it in the oven for 20 mins. Cross-cut the top, dip.
tbh, you can do this with most cheeses, just the French-style crusted cheeses provide a cool looking container.
Generic roux - oil or butter in a saucepan, add the same quantity of flour. Combine 2 mins, add milk slowly, stir. Add cheese, stir, serve.
Welsh rarebit - throw cheese, flour, milk, beer, worcestershire sauce in a pan, heat &amp; stir until it's homogenous.
There's not really much you can do to hot cheese to spoil it ;)
The only two cheeses I can think of that don't work are haloumi &amp; paneer, because they're both pre-cooked &amp; don't melt.
