Here is a quick and cheap substitute for the expensive cheeses. Use cheap chunk cheeses from your grocery store, instead of the expensive ones and drizzle a little white wine over the grated cheese. Mix it up in a bowl and let it sit while you get everything else ready. Add the cheese and any wine remaining in the bowl to your sauce, just as the recipe requires. Adding the little bit of wine to the cheese makes it taste like you used the expensive cheese.
What a great idea!
