Why did sushi and sashimi start being served with wasabi?
Many people don’t know this! Here’s a trivia quiz: Why did wasabi start being served with sushi and sashimi? Some people mix wasabi into soy sauce when eating sushi or sashimi.
But do you know why we began eating them with wasabi in the first place? The answer is: because wasabi has antibacterial properties that help prevent food poisoning.
While its sharp aroma and flavor are key attractions, the antibacterial effect makes it a win-win.
Which has higher nutritional value: fresh shiitake mushrooms or dried shiitake mushrooms?
A quiz about nutritional value! Which has higher nutritional value: fresh shiitake or dried shiitake? Here’s a fun trivia quiz.
Fresh shiitake are often cooked to highlight their texture and natural flavor, while dried shiitake have a rich aroma and are great for simmered dishes.
Both are delicious in different ways, but do you know which is more nutritious? The answer is dried shiitake.
Comparing vitamin D, dried shiitake contain about 11 times more than fresh shiitake.
Definitely something to include in your diet!
How much honey does a single honeybee collect over the course of its lifetime?
Fascinating trivia that makes you want to know the answer! Here’s a trivia quiz: How much nectar does a single honeybee collect over its lifetime? We know that honeybees gather nectar, but many of us have probably never thought about how much they actually collect.
The answer is said to be about one teaspoon.
Given that a honeybee’s lifespan is about one month, it’s believed they spend roughly two weeks of that time foraging outside.
When you think about how carefully each bee brings back its nectar, it really renews your sense of gratitude for the food we eat.
Ice cream was originally served as a kind of medicine. What was the medicine for?
On hot summer days, you really feel like eating ice cream, don’t you? Many people think of ice cream as a dessert, but it actually wasn’t originally one.
In ancient Greece and Rome, it was reportedly eaten by soldiers for recovery from fatigue and as a health food.
Back then, people would pour honey or fruit syrups over natural ice or snow and eat it.
It seems that ice cream began to be eaten as a dessert like it is today around the 16th to 17th centuries, and it is said to have been introduced to Japan from the late Edo to the Meiji period.
What will the weather be like when contrails linger for a long time?
When you look up at the sky, you sometimes see thin white streaks lingering behind airplanes.
These are called contrails—long, narrow white clouds that form after an airplane passes.
Sometimes contrails remain in the upper sky for a long time, and when they do, it’s said that rain may be on the way.
The reason is that when a low-pressure system is approaching from the west, the upper air is moist, making contrails slower to evaporate.
As a low-pressure system approaches, the weather tends to deteriorate.
Conversely, if contrails disappear quickly, it likely means the weather won’t worsen anytime soon.
What color is a red pickled plum before it’s dried?
Harvesting of ume plums begins around the start of the rainy season.
Ume can be processed into many things, such as umeboshi (pickled plums), umeshu (plum liqueur), and honey-preserved plums.
There are two types of plums used for processing: green unripe plums and fully ripe plums, distinguished by the time they are picked.
The red umeboshi are made from fully ripe yellow plums with soft flesh.
The other type is the firm green plums harvested before they ripen, which are suitable for umeshu or crunchy pickled plums.
In fact, both fully ripe plums and green plums contain toxic components.
As the fruit ripens, these toxins decrease, and once the plums are processed—by drying or pickling—they become safe to eat.
A model of an Asian giant dragonfly (oni-yanma) has an insect-repellent effect.
The Oniyanma (Golden-ringed dragonfly) is known as the largest dragonfly in Japan, characterized by its black body with distinctive yellow stripes.
Preying on moths, flies, horseflies, and wasps, the Oniyanma is considered a king of the insect world, and its prey are said to instinctively fear it and flee at the sight of it.
In fact, repellent decoys that leverage the Oniyanma’s deterrent effect are already on the market and are reportedly so popular that they frequently sell out.
Wearing one during outdoor activities or leisure outings may help you avoid insect troubles.
