Only 6 People Know the Recipe for This Delicious 'Top Secret' Tart

Pastéis de Belém, one of the original egg custard tarts, is a widely enjoyed dessert in Portugal; its namesake bakery has been known to sell an average of 20,000 tarts a day—and as many as 40,000 per day during the busy summer season. And yet, only six living people know precisely how these heavenly mini-desserts are prepared.

How exactly does one keep a recipe secret for more than 180 years? Let's just say the owners of Pastéis de Belém take this stuff very seriously: Bakers are asked to sign a nondisclosure agreement and prepare the dessert in a locked room, separated from the rest of the staff. Check out the full video from Great Big Story above—just don't expect to catch a glimpse of any secret operations. (You'll need a key for that.)

6 Signs You're Getting Hangry

Hangry (adjective): Bad-tempered or irritable as a result of hunger. This portmanteau (of hungry and angry) is not only officially recognized as a word by the Oxford English Dictionary, but it's also recognized by health experts as a real physiological state with mood-altering consequences.

That hangry feeling results from your body's glucose level dropping, putting you into a state of hypoglycemia, or low blood sugar. Glucose is the body's primary source of energy, so when you don't have enough, it affects your brain and other bodily functions, including the production of the hormones insulin and glucagon, which help regulate blood sugar. Check out the symptoms below to see if you've crossed over into the hanger danger zone.

1. IT TAKES EVERYTHING IN YOUR POWER JUST TO KEEP YOUR EYES OPEN.

Glucose equals energy, so when your blood sugar levels are low, you may start wishing you were back in bed with the shades drawn. If you start feeling sluggish or tired even though you’re well-rested, you might just need to eat something.

2. THE EASIEST ITEM ON YOUR TO-DO LIST SEEMS LIKE AN IMPOSSIBLE TASK …

It’s hard to concentrate when all you can think about is whether you're going to order the fish or beef tacos for lunch. The distraction goes beyond fantasies about food, though. The brain derives most of its energy from glucose, so when it's low on fuel, a serious case of brain fog can set in. Confusion and difficulty speaking are among the more serious symptoms you may experience when you're hangry.

3. … AND YOU HAVE A BAD CASE OF WORD VOMIT.

Blame this on brain fog too. The gray matter in your noggin goes a little haywire when blood sugar is in short supply. That's why you may start stuttering or slurring your words. You might also have difficulty finding your words at all—it can feel like your mouth and brain are disconnected.

4. YOU’RE SHAKING LIKE A LEAF AND FEEL LIGHTHEADED.

Tremors and dizziness are both signs that you should pay closer attention to your body, which is screaming, "Feed me!" Once again, low blood sugar is often the culprit of trembling hands and feeling faint, and exhaustion and stress make the symptoms worse.

5. YOUR COWORKERS SEEM ESPECIALLY ANNOYING.

You’re tense and irritable, and it’s starting to show. Hunger causes your body to release cortisol and adrenaline, the same hormones responsible for stress. This can put you on edge and lower your tolerance for other people’s quirks and irksome habits, which suddenly seem a lot less bearable.

6. YOU SNAPPED AT YOUR FRIEND OR PARTNER FOR NO GOOD REASON.

Not only are you irritable, but you’re more likely to lash out at others because of it. The doses of adrenaline and cortisol in your body can induce a fight-or-flight response and make you go on the attack over matters that—if you had some food in you—would seem unimportant.

So what should you do if these descriptions sound all too familiar? Eat a snack, pronto—one with complex carbohydrates, lean protein, and healthy fats. The first one brings up your blood sugar level, and the other two slow down how fast the carbohydrates are absorbed, helping you to avoid a sugar crash and maintain a normal blood sugar level. Eating small meals every few hours also helps to keep hanger at bay.

Alexa Can Now Help You Find a Wine Pairing

Even if you enjoy wine regularly, you may not know exactly how you’re supposed to pair it with food. But you don’t have to be a sommelier to put together a good pairing at home. According to Lifehacker, you can just ask Alexa.

An Alexa skill called Wine Finder is designed to help you figure out which wine varietal would go best with whatever food you’re planning to eat. You just have to ask, “What wine goes well with … ”

Created by an app developer called Bloop Entertainment, the Amazon Echo skill features a database with 500 wine pairings. And not all of them are designed for someone working their way through Mastering the Art of French Cooking. The skill will also help you find the proper pairing for your more casual snacks. In one demo, the skill recommends pairing nachos with a Sauvignon blanc or Zinfandel. (Note that the latter also goes well with Frito pie.)

You can also ask it to find you the perfect wine to drink with apple pie and pizza, in addition to the meats, cheeses, and other wine-pairing staples you might expect. However, if you ask it what to pair with hot dogs, it says “water,” which is an affront to hot dog connoisseurs everywhere.

There are a few other wine-pairing skills available for Alexa, including Wine Pairings, Wine Pairings (two different skills), and Wine Expert. But according to user reviews, Wine Finder is the standout, offering more and higher-quality suggestions than some of the other sommelier apps.

It’s free to enable here, so drink up.
