"Well, what do we have in the box?" asked Raj, the restaurant manager at Sofia's Tuscan Bistro.

"An American blue cheese that I use for making salad dressing," replied Jeanette, the restaurant's kitchen manager.

"But we don't have any Italian gorgonzola for the Tuscan gorgonzola steak?" asked Raj.

"No." said Jeanette. "The distributor shorted us on your order this week. But you know most people can't tell the difference between blue cheese and gorgonzola," said Jeanette. "So why don't we just use the blue cheese?"

Assume you were Raj and that you've included the phrase, "melted gorgonzola" on the menu to describe your popular "Tuscan Gorgonzola Steak" entre.

1. Would you use the American blue cheese as a substitute in the Tuscan gorgonzola steak?

2. If so, would you inform your guests of the substitution? If not, what would you do?
