In this month’s special gourmet guide we highlight that not all truffle oils are created equally. Many on the market are made in a laboratory with petroleum and aromatic molecules that simulate truffle flavor without even touching the enticing fungi. The process is cheaper and easier to produce than extracting the oil from an actual truffle and most buyers don’t have a clue. A few manufacturers do skip the lab to offer the real deal, but sufficiently ambiguous nutrition labels make discerning which is which a matter for the senses. Let Marxfoods be your guide and put your sniffer and taste buds to the test. There are worse ways to while away an afternoon.
