I'm interested in buying truffles in one form or another to be used as a seasoning for omelettes and pastas and such.
The main two truffle products available are fresh truffles and truffle oil. Truffle oil sometimes contains no real truffle, but some kind of synthetic aroma that imitates the truffle aroma (however, I'm interested in oils that have real truffle).
Price-wise, should I be looking at oils or buy straight fresh truffle and use it as I wish? I've heard a claim that truffle oils should be a more inexpensive way to get the truffle aroma, but upon comparing the prices of truffle oils with real truffle and fresh truffle, I'm not sure.
E.g. I can purchase truffle for £45 for 15g or 250ml of truffle oil for £12.50. Which one is affordable should depend on how much 250ml of truffle oil might have actual truffle and whether one would get more truffle by buying fresh truffle instead.
So should I look into purchasing and using truffle or truffle oil, if I want the most (real) truffle aroma per buck?
