What's your secret ingredient that makes your version of a common dish better than anyone else's?
Mine probably isn't that secret these days, but almost every sauce I add nutritional yeast to. Curry, chilli, bolognese, it just makes them all better.
A small splash of amaretto in macaroni and cheese. Only about a cap full, or one teaspoon, gives it an amazing sweet and salty flavour.
I discovered this incredible recipe one night when I was preparing some mac-n-cheese only to discover I was completely out of milk, and had to substitute the next best liquid I had on hand.
