Why Does Ramen Taste Better On a Rainy Day? (It's Scientific!)


Did you know that ramen actually tastes better on a rainy day? The reason is that the amount of scum produced when cooking the soup is lower than on a fair-weather day. Why is this? Read on to find out

The Reason Ramen Tastes Better on a Rainy Day

Have you ever heard someone say that ramen tastes better on a rainy day? Well, it's true, and there's a scientific basis for it.

At sea level, water boils at 100 degrees Celcius.
However, at a higher elevation, the boiling point drops. For example, water boils at 80 degrees at the top of Mt Fuji. That's due to lower atmospheric pressure.
On a rainy day, the atmospheric pressure, even at sea level, drops, as does the boiling point.

This applies to ramen because as the atmospheric pressure drops (and thereby the boiling point), the amount of scum produced during boiling is decreased.
As the soup cooks, scum forms from the bones of chicken, pork, etc. used to flavor the broth. This scum muddies the soup and contributes a bitter taste that is undesirable.

The particles released from the bones in the broth are what gives the soup it's familiar and essential umami flavor, but those same particles can turn to scum when heated above 95 degrees Celcius. However, on a rainy day, the boiling point drops below 100 degrees. As it lowers closer to 95 degrees, the amount of umami-filled particles that turn to scum are greatly reduced, and extra-delicious ramen is the result.

Indeed, the ramen chef at 'Chukka Soba Tagano' in Shinagawa-ku, Tokyo (which has been included in the Michelin Guide as a 'Bib Gourmand' restaurant for the past 4 years) agrees and says that his ramen is extra delicious on days when it's pouring rain.

Depending on the weather, many chefs change their cooking methods, ingredients, and measurements. Who knew that the weather could have such an impact on the flavor of ramen?
