A Slice of Genius: How I Accidentally Invented “The Perfect Edge”

“The discovery of a new dish does more for the happiness of the human race than the discovery of a star.”

–Jean Anthelme Brillat-Savarin (1755–1826; a French lawyer and epicure, best known for his The Physiology of Taste [1825], which remains a classic in culinary literature.)

Imagine sinking your fork into layers of luscious key lime indulgence—each bite, a symphony of tartness and sweetness that dances on your palate. This is no ordinary pie; it’s a triple-decker tower of tartness and decadence that will linger in your dreams long after the last crumb has vanished. A cinnamon-infused graham cracker crust cradles a silky baked key lime custard, perfectly set and bursting with citrus. Next comes a chilled, creamy layer that melts in your mouth, topped with a cloud of key lime whipped cream that’s just the right amount of airy. With nearly two cups of key lime juice infused into every inch, this pie is the ultimate in citrus luxury. This dessert is pure food porn—so irresistible, it’s worth every sinful calorie.

I made this Triple Layer Key Lime Pie a week ago for my Linden Correspondent (LC) and her family, who are as special to me as I hoped this pie would be to them. Obviously, I was eager to know whether my recipe measured up to my hype and their expectations. It did, and in succinct news style, my LC messaged me her family’s comments:


● It’s a work of art!
● It’s very tart/limey, which I love!
● The texture is perfect!
● How did he get a perfect 90° angle on the crust?!
● What an experience!
● The crust is divine!

And we all say:

THANK YOU!!
🤗🤗🤗🤗🤗”

I was thrilled, of course, by their reactions and returned a bold “YOU’RE WELCOME” along with my own smiley faces.

To my surprise, my friend messaged me some extra zest later in the day:

“But seriously, how DID you get the perfect angles in the crust?”

I paused, perplexed. I nearly replied with a “Duh?” Surely, it would have been clear to her that I had used a springform pan. Right? Maybe not. So, I took a cautious, mittened approach:

“But for real, what do you mean by ‘perfect angles in the crust’?”

Her reply was as precise as the apparent angles of my crust:

“The inside angle on the bottom, where the side and the bottom meet. Whatever you used to press the corners was a perfectly cornered utensil. Ours never come out like that!”

I told her that I used my fingers, but the egg whites that I added to the graham cracker mixture probably helped more.

“Your fingers? No way! My sister and I don’t believe you.”

Truly, what I told her was the truth, as I recalled it, so I decided to move on with a passing remark about the rain that had passed me by.

Later in the day, while cooking dinner, I had a strange reminder as I used one of my handy-dandy silicone tools to scrape sauce from a kitchen pot. In a flash, I remembered how I had gotten those perfect angles. After pressing the crumbs into place with my fingers, I used the silicone handy-dandy to thin and sharpen the circumference where the sides met the bottom.

I took a selfie of me holding my silicone gadget and sent it to my Linden Correspondent:

“I’m cooking dinner and came across my silicone handy dandy.

“I now remember: after pushing the crust in place with my fingers, I used this around the edges!

“Do NOT share this hack with anyone outside of your family.

“I had totally forgotten. It really helps get the job done! It was a discovery of necessity!

“Oh. No. I feel a blog coming on!”

She wittily reminded me that if I blogged about the tool that gave me those perfect edges, my secret would be out.

And so, My Dear Readers, my secret is out! I don’t mind this reveal, however, because I love you and your crumbs, and I hope that you will remember my silicone hack the next time you make a graham cracker crust. Be aware, however, that by the time you’re reading this, I will have applied for a patent, so my hack will be Patent Pending. I can do that, right? I mean. Even though the silicone handy-dandy is patented, surely I can get a new patent since I’m using it in a new-fangled way, right? (Aside to any Patent Attorneys who might be reading: please PM me and let me know if I’m losing my batter.) Well, if I can’t, I’ll just create an appropriately shaped, hand-held silicone gadget expressly designed for getting the perfect edge. OMG. This is getting even sweeter. I will call my gadget THE PERFECT EDGE. Is that perfectly sweet or what?

And isn’t it amazing that necessity drove me to invent a perfect gadget that will find its way into every kitchen in the world, even kitchens without bakers who don’t need a hack to achieve the perfect edge that they’ll never seek to achieve.

This got me to thinking—how many of our favorite kitchen gadgets and techniques were born out of happy accidents or the sheer necessity of the moment?

I know a good number of things right off the top of my head.

Did you know that Melitta Bentz, a German housewife, invented the coffee filter in 1908 when she became frustrated by the bitter taste of coffee brewed with the traditional percolator, which often left grounds in the cup? She simply took a piece of blotting paper from her son’s school notebook to filter out the grounds. She punctured holes in the bottom of a brass pot and lined it with the paper, then poured the coffee through it. The result was a smooth, grounds-free cup of coffee. She applied for a patent and gave birth to Melitta coffee filters.

It’s funny to think that a simple frustration with coffee grounds led to the creation of something so essential to our morning routines. And even if you didn’t know about coffee filters, surely you know about Teflon. In 1938, Roy Plunkett, a chemist working for DuPont, was experimenting with refrigerants and discovered that one sample had polymerized into a white, waxy solid that was extremely slippery. This substance? Polytetrafluoroethylene (PTFE). We know it as Teflon. Although initially used in military applications, Teflon’s non-stick properties made it an ideal coating for cookware. The first 1950s Teflon-coated pan became a game-changer in every kitchen throughout the world except mine. I’m sticking with my All-Clad. I don’t want any of that PFTE stuff slip-sliding into my culinary delights. While Teflon revolutionized non-stick cooking, I’m more of a stainless-steel purist. There’s something about the weight and durability of All-Clad that speaks to my culinary soul.

And who doesn’t know about Percy Spencer’s 1945 accidental invention of the microwave? While testing a magnetron, a type of vacuum tube used to generate microwaves for radar systems, he noticed that a candy bar in his pocket had melted. So he tried popping some popcorn kernels near the magnetron. Yep. Pop. Puff. Burst. Next? An egg, which exploded in his colleague’s face. (Just as an aside. That is not the origin of the expression, “Egg on his face.”) Spencer and his team saw the potential to cook food quickly. They built the first microwave oven, standing over six feet tall and weighing nearly 750 pounds. “Radarange” was released commercially in 1947. Is that rad or what? Personally, I’m not a huge microwave fan, but I’m awfully glad they’re compact enough and affordable enough to be in any kitchen, including mine.

Let’s throw one more gadget into this mash. The potato peeler. Please tell me that you’re not using a knife to peel your spuds the way folks had to before Alfred Neweczerzal, a Swiss engineer, designed the potato peeler found in kitchens throughout the world. It’s simple. It’s lightweight. It’s effective. And it’s probably the cheapest gadget in my kitchen.

If you think gadgets invented by accident are fun, just wait until you hear about some of the delicious foods that came to be thanks to a stroke of serendipity—or perhaps sheer clumsiness. Let’s dive into the culinary cosmos where mishaps turn into mouthwatering miracles.

I’ll start with sourdough not only because you will remember by post, “Oh, No! Sourdough!” but also because I’m still foolin’ around with sourdough at least once a week, sometimes more. Did you know that sourdough is one of the oldest forms of leavened bread, and its origins can be traced back to ancient Egypt, around 4,000 BC? But here’s the savory backstory. A baker accidentally left out a mixture of flour and water, which naturally attracted wild yeast from the environment. The yeast fermented the dough, causing it to rise and develop a tangy flavor. Today, we call it sourdough fermentation, and it’s the foundation for one of the world’s most beloved breads. Just last week, I made two loaves of triple cheese sourdough: Cheddar, Gruyere, and Parmesan. My kitchen smelled like a bakery for days after I gave the loaves to friends.

And you might not think that bread and beer go hand in hand, but they have grains and grains of connection. The invention of beer is often attributed to a happy accident. The Sumerians around 5,000 BC likely discovered beer when wild yeast fermented stored grains or bread that had gotten wet. The resulting liquid had a pleasant taste and intoxicating effects, leading to the intentional brewing of beer and the unintentional drunkenness and debauchery that sometimes sip along. This process became a cornerstone of many cultures and is one of the earliest known examples of fermentation.

Enough of yeasties. Let’s move on to sweetsies, especially chocolate chip cookies. They came about not by accident but rather by necessity. In 1938, Ruth Wakefield, owner of the Toll House Inn in Massachusetts, was trying to make chocolate cookies. When she ran out of baker’s chocolate, she decided to use chopped-up bits of a Nestlé semi-sweet chocolate bar instead, expecting the chocolate to melt and blend into the dough. To her surprise, the chocolate pieces retained their shape, creating the first chocolate chip cookies. These cookies became so popular that Nestlé struck a deal with Wakefield, allowing them to print her recipe on their chocolate bar packaging, which eventually led to the creation of chocolate chips. Thank God for necessities.

This next culinary delight came about not by necessity, not by accident, but by frustration. Get ready to crunch. Way back in 1853, George Crum, a chef in Saratoga Springs, New York, got frustrated with a customer who repeatedly sent back his fried potatoes, complaining they were too thick and soggy. In an attempt to annoy the customer, Crum sliced the potatoes as thin as possible, fried them to a crisp, and added extra salt. To his surprise, the customer loved them, and thus, the potato chip was born. Without a doubt, the necessity here was to please a picky customer, but the humorous twist is that the invention was born out of frustration.

How about this next twist? What do you get if you put potato chips and chocolate chips together? Potato Chip Cookies! That’s no joke. I found the recipe on the Internet by accident, made the cookies one day out of necessity when I was having a sugar fit, and satisfied my frustration with a fascinating plate of crunchy, sweet, tongue-tip salty cookies and a glass of milk.

But I’m going to take that recipe and spin it like a top! You know what I’m going to do? Well, let me give you a hint. The star ingredients will be Potato Chips, Chocolate Chips, and … SOURDOUGH! Yep! You heard it first right here! Sourdough Potato Chip Cookies! Now, you might be wondering—how do these flavors work together? Here’s the secret: the tangy complexity of the sourdough adds a unique depth to the cookie, balancing out the sweetness of the chocolate chips and the saltiness of the potato chips. It’s a trifecta of flavor that hits all the right notes—crunchy, sweet, salty, and just a little bit sour. The sourdough brings an unexpected twist to the classic cookie, giving it a subtle chewiness and a hint of that signature tang that keeps you reaching for just one more. Once again, sourdough will rise to the occasion, taking me—and your taste buds—to a place we’ve never been before

There you have it, My Dear Readers! Mark your calendars! This is a double red-letter day. In the annals of culinary history, I’ll be memorialized not only for inventing Sourdough Potato Chip Cookies but also for inventing The Perfect Edge, both living proof that kitchens give birth to genius–chip by chip and slice by slice.
