I love the taste if edam cheese and I want to know if I can make a sauce with it? Like the sauce with the roux+milk+cheddar can I replace cheddar with edam?
AFAIK, you should be OK.
It is a hard cheese, similar but different than cheddar, but should work.
You might have to experiment a little bit, even if the cheeses are similar, their behavior when melting might be different.
