Easiest, Least Expensive Way to Make Your Coffee Taste Better

Why is my coffee bitter? It doesn't make any sense. I mean, sure, it's got a lot of bitter flavor compounds in it, and sure, the tongue supposedly has those taste receptors just for bitter flavors so that we don't eat poisonous things or something, but my coffee can be tastier. I've had tastier coffee. What am I missing?

Salt.

That's it. A tiny bit of salt in the coffee.

Did I just blow your mind?

I found this one though Ideas in Food, who found out about it through Shirley O. Corriher. So, what's going on here?

As mentioned before, we've been taught in elementary school about the taste receptors in our tongues that handle sweet, salty, sour, and bitter. Perhaps even umami, though we probably weren't taught that in elementary school. Well, I wasn't.

But we know that food is far more than the combination of those flavors. Flavor compounds combine in strange ways and float up through the nasal cavities and coat the tongue in more subtle variations to the simple way taught in schools.

When I drink coffee, I'm not really all that interested in the bitter. Therefore, I'll use the espresso machine and make a double ristretto, which is effectively a full espresso's worth of water over two espresso's worth of beans. This extracts lots of flavor and not that much bitter.

Still, the double ristretto uses a lot of beans. What if there were some magical substance that made flavors more noticeable? What if a simple, two-atom molecule could turn bland foods into taste explosions? Wouldn't the world be a better place if it existed? Wouldn't we all be happier?

Yes, yes we would. Because we have salt, all of our lives are more fulfilling. Magic does exist in the world. And, if you sprinkle a little bit of this magical fairy dust into an espresso, so 10-15 flakes of kosher salt, for example, all of the flavors that aren't bitter are amplified. A single, normal cup of espresso tastes like a double ristretto.

Seriously, how cool is that?

The folks over at Ideas in Food will now be going crazy with experimentation on standard beverages with the addition of salt. I'm sure we'll hear new things as time goes on. Personally, I couldn't be more pleased learning about this one, except insofar as I did not think of it, nor even think to think of it.
