Scientists have figured out what makes Indian food so delicious


Indian Food

 Indian food, with its hodgepodge of ingredients and intoxicating aromas, is coveted around the world. The labor-intensive cuisine and its mix of spices is more often than not a revelation for those who sit down to eat it for the first time. Heavy doses of cardamom, cayenne, tamarind and other flavors can overwhelm an unfamiliar palate. Together, they help form the pillars of what tastes so good to so many people.

But behind the appeal of Indian food — what makes it so novel and so delicious — is also a stranger and subtler truth. In a large new analysis of more than 2,000 popular recipes, data scientists have discovered perhaps the key reason why Indian food tastes so unique: It does something radical with flavors, something very different from what people tend to do in the Western culture. And it does it at the molecular level.

Before we go further, let’s take a step back and consider what flavors are and how they interact. If you were to hold a microscope to most Western dishes, you would find an interesting but not all-too-surprising trend. Popular food pairings in Western world combine ingredients that share like flavors, which food chemists have broken down into their molecular parts — precise chemical compounds that, when combined, give off a distinct taste.

Most of the compounds have scientific names, though one of the simpler compounds is acetal, which, as the food chemist George Burdock has written, is “refreshing, pleasant, and [has a] fruity-green odor,” and can be found in whiskey, apple juice, orange juice and raw beets. On average, there are just over 50 flavor compounds in each food ingredient.

A nifty chart shared by Scientific American in 2013 shows which foods share the most flavor compounds with others and which food pairings have the most flavor compounds in common. Peanut butter and roasted peanuts have one of the most significant overlaps (no surprise there). But there are connections that are more difficult to predict: strawberries, for instance, have more in common with white wine than they do with apples, oranges or honey.

Chefs in the West like to make dishes with ingredients that have overlapping flavors. But not all cuisines adhere to the same rule. Many Asian cuisines have been shown to belie the trend by favoring dishes with ingredients that don’t overlap in flavor. And Indian food, in particular, is one of the most powerful counterexamples.

The cuisine is complicated, the average Indian dish, contains at least 7 ingredients, and the total number of ingredients observed by the researchers amounted to almost 200 out of the roughly 381 observed around the world. But all those ingredients — and the spices especially — are all uniquely important because in any single dish, each one brings a unique flavor.

Combining ingredients with like flavors is a useful (and often delicious) strategy, but it might be a somewhat misleading rule of thumb. Indian cuisine, after all, is cherished globally, and yet hinges on a decidedly different ingredient pairing logic.
