The Secret to Homaro Cantu's Genius

Last week, the legendary chef Homaro Cantu took his own life. It’s a sad and familiar story of someone too talented leaving us too soon. At mental_floss, we were very much in awe of Cantu’s special breed of genius. And we were floored by his ambitions (one of the many things he expected to do was to use edible paper soaked with nutrients to end world hunger). Eight years ago we put him on our New Einsteins list for all the madcap inventing he was doing on and off the plate. He was one of the first interviews we ever landed (we had our pal Erik Vance report the story), and couldn’t have been nicer, giving his time to a little magazine from Birmingham. Just a few weeks ago, I was wondering about something he’d said in this interview—that he’d figured out a way to flip a gene that would turn tomato plants into organic nightlights, and I made a note to myself to schedule a follow-up. Unfortunately, we never got the chance. In light of Cantu’s passing, I thought it would be a good time to post this short interview. I remember reading Cantu's words and feeling inspired to tinker and invent and dream bigger. I’m hoping others will stumble into this interview and feel the same way.

The Restless Chef

by Erik Vance

In the back of Homaro Cantu’s chic Chicago restaurant, Moto, hangs a Salvador Dalí poster that reads, “The only difference between a madman and me is that I am not mad.”
It’s in the right place. With his penchant for cooking with lasers and liquid nitrogen, Chef Cantu has created one of the edgiest dining experiences in the country. On the Moto menu, you might find doughnut soup, flapjack popsicles, and, to drink, a glass of vanilla-bean smoke. “First we shock people, and then we awe them with the fact that this stuff is real food,” Cantu says. “If it doesn’t make you go, ‘Holy sh**, that was the greatest spaghetti I’ve ever eaten—and it looked like a cheeseburger!’ then it’s just not worth it.”
As a teenager in California, Cantu says he was on a one-way track to juvenile hall when a high-school science teacher got him hooked on science. A love for experimentation led to a passion for tinkering in the kitchen, which eventually evolved into his peculiar brand of high-tech gastronomy. Obsessed with new ideas, Cantu believes he is more inventor than chef. Indeed, he spends many waking hours on projects that have nothing to do with cooking, such as making tomatoes glow in the dark. Recently, mental_floss grabbed a few minutes on the phone with Cantu to ask him about his latest pursuits. In a dialect that’s one part California surfer and one part Chicago construction worker, he tends to throw ideas around one on top of the next. All them could be dismissed as hare-brained, except that most of them are proving remarkably successful.

Q: What is the worst thing you’ve ever created?
A: This thing called the Black Course. It was calamari with red sauce, but everything was pitch black. The ladies didn’t like it because after about five minutes, their lips and their teeth turned black. They’d be looking at their date and trying to be sexy, but they weren’t very sexy.

Q: You’ve been working with products from a company called American Anti-Gravity. What’s that about?
A: This guy created a particle gun that pumps out 40 watts of negative ions, which can levitate some objects. As soon as I saw it, I thought, ‘We’ve got to see if there are any edible products that we can electrify to make them float around!’ And that’s when I thought of salt. You can actually charge certain types of sodium chloride so that they store energy, which can be released on demand.

Q: So you had levitating salt floating around your restaurant?
A: Yeah. We were just shooting salt with this particle gun, and it bounced around. It was cool and novel, but how do you turn that into a product? Instead, it led me to this other invention I’m working on now that’s essentially going to turn every building in America into a net energy producer. It’s a motor that I’m hoping will create more energy in a building than the building consumes. I’ve got eight households in my neighborhood that use it, and they’re going to start cutting me checks for all the energy they’re saving.

Q: Why do you think there’s an energy crisis?
A: Because we’re over-thinking everything these days. I’ll give you one example. Tomatoes actually have a gene in them that can be switched on and off, enabling them to glow in the dark. And if a tomato can throw off 240 lumens, that’s equivalent to 10 LED lights. So you take your tomatoes and you put them in an upside-down planter and you grow them, and then they glow at night. I think the key to unlocking energy potential is looking at food as a means of dense energy storage. If you could take something that you can eat and use it to light your home, that’s a double whammy. When it’s ripe, it burns out and you eat it! Man, that’s how we’ve got to start thinking.

Q: How long do you work every day?
A: [loud, grinding, whirring sound] Until six o’clock.

Q: Hello? I think I’m losing you. Did you say you work regular hours?
A: Yeah. Sorry about that background noise [sound goes to a lower pitch]. That thing you heard right there is a motor I’m working on.

Q: The net energy producer?
A: No, this one’s a little different. It’s an internal combustion engine for a remote-controlled car that uses hydrogen gas to boost the car’s fuel economy by 60 percent. The hydrogen gas is extracted from falling water. I know that sounds weird, but any building can do it. Everyone in my neighborhood watches me come out here every day with this thing.

Q: [More grinding] Are you working on the motor as we speak?
A: Yeah, I just fired it up again.

Q: Do you do this often, or am I getting a treat?
A: I do it quite a bit, actually.

Three Questions
1. What piece of advice has stuck with you?

Never be too good to listen. My first chef taught me that. I listen to everybody, including my dishwashers.

2. What would you have been if not a chef?

What I am right now—an inventor. I haven’t handled a single piece of food today, just so you know.

3. What is “genius”?

Doing unconventional things. Lock yourself in a room with two things and stare at them. Inspiration is everywhere, but you have to be willing to sit there and do what it takes to create the end result.

Why You Never See Fresh Olives at the Grocery Store

If given a choice, most grocery shoppers prefer fresh produce over something that's been pumped full of preservatives. Yet shoppers are almost never given that choice when it comes to olives. The small, meaty fruits can be found floating in brines, packed in cans, and stuffed with pimentos, but they're hardly ever shipped to the store straight off the tree. As the video series Reactions explains, there's a good reason for that.

In their natural state, because they contain high concentrations of a bitter-tasting compound called oleuropein, fresh olives are practically inedible. To make the food palatable, olive producers have to get rid of these nasty-tasting chemicals, either by soaking them in water, fermenting them in salt brine, or treating them with sodium hydroxide.

Because of its speed, food manufacturers prefer the sodium hydroxide method. Commonly known as lye, sodium hydroxide accelerates the chemical breakdown of oleuropein into compounds that have a less aggressive taste. While other processes can take several weeks to work, sodium hydroxide only takes one week.

Afterward, the olives are washed to remove the caustic lye, then packed with water and salt to extend their shelf life, giving them their distinct briny flavor.

For more on the chemistry of olives, check out the full video from Reactions below.

Why Do Sour Things Make Me Pucker?

WHY? is our attempt to answer all the questions every little kid asks. Do you have a question? Send it to why@mentalfloss.com.

Have you ever sucked on a lemon and felt your face scrunch up? Foods that are very sour contain a lot of acid and can make you pucker—wrinkle your face, squint your eyes, and press your lips together. When things like lemons, vinegar, and unripened fruit touch your tongue, your brain gets a signal that you’re eating something sour. It could be your body's way of saying "watch out!"

Your tongue has thousands of little bumps with tiny sensors called taste buds. Taste buds let you know when something is sweet, salty, sour, bitter, or savory. (Savory is also called umami. Say: ooo-MOM-eee.) Each taste bud has dozens of taste cells that have little sprouts on them that look like hair that can only be seen with a microscope. When foods dissolved in your saliva touch them, they tell the brain about the flavor of what you are eating. When they come in contact with very sour foods, your face might pucker up because the taste is strong and acidic.

Puckering when you taste something sour is often involuntary (in-VAWL-uhn-ter-ee). That means you do it without trying. It may happen because we have an instinct not to eat things that are dangerous. Of course, not all sour foods are bad for us. But some sour foods can make us sick—spoiled milk or fruit that is not ripe, for example. Reacting with a wrinkled-up face may be our body’s way of trying to warn ourselves and others to stay away from foods that might hurt us.
