Just 15 minutes after the very first Cheesecake Factory opened in Beverly Hills back in 1978, the lines began forming. Here's their cheesecake twist on the delicious Key lime pie. Since Key limes and Key lime juice can be hard to find, this recipe uses standard lime juice which can be purchased bottled or squeezed fresh. If you can find Key lime juice, bear in mind that Key limes are more tart, so you'll need only half as much juice. This recipe also requires a springform pan. If you don't have one, you can use two 9-inch pie pans and make two smaller cheesecakes.

Barney's Beanery, the self-proclaimed "third oldest restaurant in Los Angeles," has a long history of celebrity patrons dropping by for a hot bowl of chili and a beer or three. John "Barney" Anthony opened the first Barney's Beanery in Berkley, California in 1920, and seven years later relocated the restaurant to its current location on Santa Monica Boulevard in West Hollywood.

Barney's soon became a popular watering hole for film stars from the 1920s and '30s, such as Clara Bow, Clark Gable, and John Barrymore. In the '50s and '60s Lou Costello was a regular, and so were Donald O'Connor, Charles Bukowski, and Dennis Hopper. Jim Morrison and his Doors bandmates were frequent customers since the offices of their record label, Elektra, were nearby. Janis Joplin was said to have had a drink there the night she died. The Brat Pack of the '80s—Charlie Sheen, Rob Lowe, John Cusack, Emilio Estevez, and Demi Moore—would often come in to play pinball and video games. And Quentin Tarantino wrote most of his screenplay for Pulp Fiction while sitting at his favorite booth at Barney's.

This original chili was a favorite of Peter Falk's character on Columbo, who ate it often at the restaurant on the TV show. But the show wasn't filmed at the actual location. The Barney’s Colombo viewers saw on their TV was a sound-stage replica.

The secret to the flavor of this Barney's Beanery chili recipe comes from two chili powders that were popular in the West over 100 years ago, around the time Barney's first opened: Gebhardt and Mexene. Chili powders were new at that time, and there were very few on the market, so it's highly likely these ingredients were used in the recipe that made Barney's Beanery famous. Find those two chili powders and you're well on your way to hacking a classic chili. 

Menu Description: "Smoked ham, smoked turkey, two cheeses, battered and fried until golden with raspberry preserves and dusted with powdered sugar."

When pondering casual chains with the best Monte Cristo sandwiches, two come to mind: Bennigan's and Cheddar's recipes. At each chain the sandwich is built with turkey, ham, and cheese, then it’s battered and fried, dusted with powdered sugar, and served with raspberry preserves for dipping. It probably sounds strange if you've never had one, but Monte Cristo alums know it all tastes pretty darn great together. I hacked Bennigans' version years ago for my cookbook Top Secret Restaurant Recipes 2, and recently, on a trip to Charlotte, North Carolina, I was able to get my hands on Cheddars' signature version of this famous sandwich.

I planned for the mission by bringing along a cooler of ice so that I could get a fresh sample safely back home. Once I was back in the lab in Vegas, I subjected the sandwich to a series of tasty tests, burned through several versions of batter, and eventually assembled this new Cheddar's Monte Cristo copycat recipe that I think is even better than my previous Bennigan's hack. The better batter is the big secret here—it's light and crispy and perfectly golden brown, and the sandwich features two kinds of cheese, both white and yellow American. Will this be the best Monte Cristo you've ever had? You’re about to find out.

KFC's Chicken Pot Pie is a classic. It's packed with lots of shredded white and dark meat chicken, potatoes, peas, and carrots; all of it swimming in a delicious creamy gravy and topped with a tantalizing flakey crust. It seems more like homemade food than fast food. And now it can be made at home better than ever before with this improved hack of my original recipe. The crust now has a better flavor (more butter!), and the gravy tastes closer to the original with the addition of more spices.

You can make these in ramekins or small oven-safe baking dishes, or get some recyclable aluminum pot pie pans you can find in many supermarkets. Those pans are the perfect size for four single servings, and they make cleanup easy after the feast.

It was only a matter of time before the spicy fried chicken made famous in Nashville, Tennessee at shops like Prince's Hot Chicken Shack and Hattie B's would find its way into the mainstream. A dish this good is never contained forever, and KFC became the first fast food chain to give the recipe national exposure. A test run of the new spicy chicken in Pittsburgh was the most successful product test in KFC's recent history.

The original dish from Nashville is made with crispy fried chicken that's doused with a top-secret spicy chili sauce and served on sliced white bread with dill pickles on top. KFC's version is served with just pickles, no bread (a biscuit on the side instead), and is made by soaking the chain's Extra Crispy Fried Chicken with the oily chili sauce from a squirt bottle. Since there isn't any water in the sauce, just oil, the chicken stays crispy, regardless of how much sauce is applied.

To make a home version, you first need to make some chicken, either using my hack for KFC Extra Crispy Chicken, or by baking or frying some of the pre-breaded chicken pieces you can find frozen in just about every grocery store. While the chicken cooks, make the sauce and pour it into a squirt bottle or spouted measuring cup. Apply it to your chicken when it's done (shake it or stir it first!), then top it with dill pickle slices.          

What started as a single food cart in Madison Square Park in New York City in 2000 has become one of America's fastest-growing food chains. In 2014, Shake Shack filed for its initial public offering of stock, and shares rose by 147 percent on the first day of trading. The chain’s success can be attributed to a simple menu of great food that makes any bad day better, including juicy flat-grilled burgers, thick shakes, and creamy frozen custard.

Custard is made just like ice cream with many of the same ingredients, except custard has egg yolks in it for extra richness. Also, custards are made in ice cream machines with paddles that move slowly so minimal air is mixed in. Home ice cream makers work great for custard, and will churn out a thick, creamy finished product. Using the right ratio of cream to milk and just enough egg yolks, sugar, and vanilla, you can now make an identical hack of Shake Shack’s custard, which is great on its own or topped with syrups, fruit, and candy bits. 

And don’t forget that custards taste best when they’re fresh. Shake Shack serves the custard within a couple of hours of making it, so consume your copycat custard as quickly as you can after it’s churned.

Since Panera Bread makes all its ingredients known, it's not hard to find out that there’s no chicken broth in the original recipe, yet every copycat recipe I located online calls for chicken broth, as well as other ingredients clearly not found in Panera's version. Unlike those other recipes, this hack uses the same or similar ingredients to those listed on the company’s website.

One of the ingredients in the soup, according to the posted list, is yeast extract. This tasty ingredient adds an MSG-like savoriness to Panera’s soup, and we can duplicate it by using nutritional yeast—often called "nooch"—now found in many stores, including Whole Foods. A little bit of nooch will provide the umami deliciousness that replaces chicken broth or bouillon.

Panera keeps its soup gluten-free by thickening it with a combination of rice flour and cornstarch, rather than wheat flour. I’ve included those ingredients as well so that your clone is similarly gluten-free. Use the steps below and in about an hour you’ll have 8 servings of a soup that is a culinary doppelganger to Panera Bread's all-time favorite soup, and at a mere fraction of the cost.

Panera Bread’s product information pages refer to a long proofing time when describing the sour characteristic of the chain’s phenomenal bagels, but there is no mention of how long. After several weeks of trying different approaches to proofing these cinnamon bit–filled bagels, I decided the best solution was to form the bagels and proof them overnight in the cold. The next day the bagels came out of the refrigerator not much bigger, but after sitting for several hours at room temperature they more than doubled in size and had a light sourdough flavor like the original.

The cinnamon drops that go into the bagel were also tricky. I needed to come up with a way to make bits of cinnamon/sugar that were crunchy, but not so hard as to break a tooth. I found the best way was to make oven-cooked cinnamon candy bound with cornstarch and milk and tenderized with oil. This sugar mixture is baked in a loaf pan until no longer bubbling, then cooled and shattered into tiny pieces. When the candy is broken up, much of it gets pulverized into dust, which you separate from the crumbs with a sieve. The crumbs are the cinnamon drops used in the bagel, and the cinnamon/sugar powder is used to dust the tops of the bagels just before baking.

I also found that kettling (boiling the bagels) with just a tablespoon of sugar in the water produced a browner bagel than kettling with no sugar, so that’s the technique I’m sharing here. Some techniques call for malt in the water, but sugar works just fine and makes the perfectly shiny, blistered crust you see in the photo.

It’s about time for Top Secret Recipes to hack one of Starbucks all-time bestselling baked snacks. For this banana bread knock-off, I settled on a blend of both baking powder and baking soda for a good crumb and dark crust that perfectly resembles the original. And I decided it best to go big on the dark brown sugar, not only for flavor but also because the extra molasses in the darker brown sugar triggers a helpful leavening boost from the baking soda. It’s also important to know that an accurate clone must have both walnuts and pecans in the mix, because that’s what’s really in it, according to the official Starbucks website ingredients info. All other copycats I saw got it wrong when it came to the nut blend, so if you want a true clone, this is the hack to bake.   

I've cloned a ton of drinks and treats from Starbucks. See if I hacked your favorite here.      

My favorite new Denny’s pancakes are these tasty whole-grain-filled buttermilk flapjacks, peppered with healthy flax seeds. At the base of the formula is my hack for Denny’s buttermilk pancakes, and to that I’ve added whole wheat flour, a little flax seed, and a hot cereal blend with nine different grains in it. Okay, mine had ten grains in it, but who’s counting?

Regardless of how many grains are in the cereal blend you use, I find it best to give the grains a quick soak to soften them up before making the pancakes. Just let the cereal and flax seeds rest for a bit in the liquid before mixing them into the dry ingredients.
