If you’ve ever had to chop an onion，you probably know that it’s one of the most annoying cooking experiences．It just fills your eyes with tears．Scientists and farmers have been working on a solution to this problem for decades，and they’ve apparently come up with a tearless onion．

Called the“Sunion”，this new vegetable is the result of a natural cross-breeding program that’s been going on farms in Nevada and Washington since the 1980s．It’s supposedly a sweet，mild-tasting onion that doesn’t leave that strong，pungent aftertaste，but what really sets it apart from most other onion varieties is that it doesn’t cause teary eyes when it’s chopped．

When you cut into a normal onion，it releases a compound called lachrymatory-factor synthase，and’when that hits your eyes，your body produces tears．Now，the interesting thing about regular onions is that the amounts of lachrymatory-factor synthase increase the longer the vegetables are stored，so the older they，the more you cry．In Sunions，on the other hand，the levels of that annoying compound drop the more time goes by，until it no longer has any effect on your eyes when you cut it．

That’s what Sunion growers are claiming anyway，but reports from those lucky enough to have tried them seem to confirm these claims．The Huffington Post had three of its reporters chop some Sunions，and apparently，none of them shed a single tear．According to the Washington Post，they don’t have the pungency of regular onions and are so sweet that you can eat them“like popcorn”．

So the good news is that tearless onions are now a real thing．The bad news is that they are currently only grown in Washington and Nevada，and even though they are sold nationwide，they are still in relatively short supply．The first Sunion batches hit the shelves of grocery stores in December，but we’11 probably start seeing them in most grocery shops and supermarkets in the next few years，as more people learn about them．

One of the most popular street food found in China is no doubt the barbecue. A new program, called Chinese Barbecue, tells the story of this popular food cooked over hot coals on just about every street corner in cities and towns across the country. Barbecued meat is an important part of people’s nightlife.

Shown on June 20, the program has had more than 25 million clicks on the video site bilibili.com. To find the most popular barbecue stalls (摊位), the production team travelled to more than 500 locations in 30 cities across the country. Some viewers compare Chinese Barbecue to Midnight Diner, a Japanese TV program telling stories from late night informal Japanese bars.

“I’m happy to hear this comparison because Midnight Diner is a good program, and we share the same topic― night food,” Chinese Barbecue’s director Chen Yingjie said. “However, they are quite different.” He said that Midnight Diner focused more on food itself, though there was some conversation while people were eating. However, the night food scene of Chinese people means joy and a more lively atmosphere. People eating these barbecue snacks develop a feeling of connection, which can be a cure for loneliness.

The barbecue, regarded as the most ordinary and common night street snack, is different from home-made food by mothers as that is a symbol of family and kinship. The barbecue is where you go to become connected to people in society. And unlike official business lunches, during which people are rather polite, the barbecue lets people relax with old friends and new friends, leaving a lasting impression of friendship.

The world, as a whole, holds deep-rooted good feelings toward the barbecue, either for the taste or the warmth produced by fire. “What we should do is to present the Chinese barbecue just the way it is because with its special ingredients(食材)，ways of cooking and more importantly, the special environment and people, the world will recognize it and might fall in love with it just as we do.” said Chen.
