The combination of garlic and onions is a staple in many cuisines around the world. From savory sauces to aromatic stir-fries, these two ingredients are often used together to add depth and complexity to a wide range of dishes. But have you ever stopped to think about whether garlic and onions truly go well together? In this article, we’ll explore the relationship between garlic and onions, and examine the science behind why they’re so often paired in cooking.
The History of Garlic and Onions in Cooking
Garlic and onions have been used in cooking for thousands of years, with evidence of their use dating back to ancient civilizations in Egypt, Greece, and Rome. In these cultures, garlic and onions were valued not only for their flavor, but also for their medicinal properties. Garlic, in particular, was believed to have antibacterial and antiviral properties, and was used to treat a range of ailments from colds and flu to indigestion and skin conditions.
Onions, on the other hand, were prized for their sweet, mild flavor and were often used in cooking to add a touch of sweetness to savory dishes. The ancient Greeks and Romans used onions in a variety of dishes, including stews, soups, and salads, and they were also used as a form of currency in some parts of the world.
The Science of Flavor Pairing
So why do garlic and onions go so well together? The answer lies in the science of flavor pairing. When we eat, the molecules of the food we’re consuming bind to receptors on our tongues, which send signals to our brains that allow us to perceive different flavors. Garlic and onions both contain molecules that bind to these receptors, but they do so in different ways.
Garlic contains a molecule called allicin, which is responsible for its pungent flavor and aroma. Allicin binds to the sulfur receptors on our tongues, which are responsible for detecting the flavor of sulfur-containing compounds. Onions, on the other hand, contain a molecule called quercetin, which binds to the sweet receptors on our tongues.
When we eat garlic and onions together, the allicin in the garlic binds to the sulfur receptors on our tongues, while the quercetin in the onions binds to the sweet receptors. This combination of flavors creates a rich, savory taste that is greater than the sum of its parts.
The Role of Sulfur in Flavor Pairing
Sulfur plays a critical role in the flavor pairing of garlic and onions. Sulfur is a naturally occurring element that is found in many foods, including garlic, onions, and cruciferous vegetables like broccoli and cauliflower. When we eat sulfur-containing foods, the sulfur molecules bind to the sulfur receptors on our tongues, which sends a signal to our brains that we perceive as a pungent or bitter flavor.
Garlic and onions both contain high levels of sulfur, which makes them a natural pairing. The sulfur molecules in garlic and onions bind to the sulfur receptors on our tongues, creating a rich, savory flavor that is characteristic of many cuisines around the world.
