How Mathematicians Solve the Problem of Even Cake Cutting

Cutting a cake can be tricky, especially if you have to make sure everyone gets an equal slice. Thankfully, mathematicians have come up with a way to solve this problem.

It’s an idea that could also help you divide up a loaf of bread evenly. Check out the video below to learn how it works. 주문제작케이크

1. Use a Serrated Knife

If you’re a cake maker, you know that a quality knife set is key to making clean and even cuts for your creations. The best knives come with a sturdy, comfortable handle, and the blade material, length, thickness, and shape can impact how well they cut.

Serrated knives are ideal for slicing spongy ingredients like cakes. The ridges on the blade grip the ingredient, allowing you to slice through with minimal pressure. They also work well with soft frostings that could get crushed with a straight blade. A small serrated knife, like the one you use to cut tomatoes, works best for this task.

If you don’t have a small serrated knife, a serrated bread knife is an acceptable alternative. Just be sure to wipe off the blade between slices to remove any crumbs or frosting. This will help you achieve clean slices and serve a delicious slice of cake to your guests.

2. Set the Cake on a Stand

If you’re hosting a wedding extravaganza or a party that calls for a showstopping cake, a stand is the final piece of a beautifully crafted centerpiece. Whether you opt for a classic pedestal design or a glass dome, the right cake stand will give your dessert a sense of depth and height to make sure your show-stopping showstopper makes a lasting impression on your guests.

Putting your cake on a stand also helps you avoid making a mess. Frosting is easier when the cake is higher and closer to eye level, which means you can work faster without a lopsided or gloopy mess.

Depending on the style of your event, you may want to have the cake cutting ceremony before or after dinner. If you prefer to do it after, you can have the catering team distribute undecorated sheet cakes to your guests for them to enjoy while they eat. This is often a more budget-friendly option than having your guests wait until after the main course to get their dessert. It will also help keep the cake from becoming stale too soon.

3. Use Floss

If you don’t have a large serrated knife, or don’t want to shell out money for a cake slicer specifically designed for layer cakes, this handy hack using floss is the perfect solution. It’s a simple technique that’ll get you perfectly even slices every time and helps you avoid cake crumbs getting mixed into the frosting.

In a TikTok video that’s been viewed nearly 3 million times, popular YouTube chef Dan Langan shows how to use a piece of unflavored dental floss (or twine or invisible sewing thread or heavy fishing line) to subdivide a cake into perfectly-even slices. The best part is, this method preserves the beautifully defined layers of cake and buttercream so you’ll never have to worry about anyone saying their slice doesn’t taste right.

To do this, stick a row of toothpicks halfway up the side of a cake, then cut a length of unflavored floss that’s long enough to wrap around the whole row. Then, tightly wrap the floss around the entire cake, cross the ends of the floss and pull them firmly to cut the cake.

4. Cut in Half

When it comes to food, cutting recipes in half can be a great way to save time and money. However, it’s important to understand how to properly halve a recipe so you can get the best results possible. This will help you make the most out of your ingredients and cut down on waste.

To cut a cake layer evenly, start by chilling the entire cake completely in the fridge. Then, score the entire surface of the cake with a long serrated knife to mark its halfway point. Next, gently saw slowly and horizontally through the cake. If you have a cake turntable, this helps with the process by gradually rotating the cake as you go.

Once you’re through with the first slice, you can use toothpicks and unflavored dental floss to secure the remaining piece of cake in place. Then, slide cardboard or a baking sheet between the two pieces of cake to create a clean and even slice. Finally, use a cake lifter or two spatulas to carefully remove the top cake layer.

5. Take a Piece

Cutting a cake seems like a simple task, but anyone who’s watched someone hack at a gorgeous celebration dessert knows that it can go horribly wrong. If the person cuts too few slices, or even worse, overdoes it on the first slice leaving you with a slither, it’s not just annoying but downright heartbreaking.

Fortunately, there’s an elegant solution. As Aziz and Mackenzie explain, there’s a mathematical algorithm (which mathematicians John Selfridge and John Conway independently came up with around 1960) for dividing some continuous object—be it a piece of cake or a tract of land—among people who value different aspects of it differently.

Australian baker Katherine Sabbath (the queen of neon drip cakes who helped usher in the unicorn trend) posted this Instagram video of her friend slicing one of her treats using the method, and it caused a storm. Essentially, Sabbath makes horizontal slices across the cake and then flips each of those pieces onto a cutting board, where they’re cut into strips about one-inch thick. This way, a cake that would normally serve six to eight people can serve 30.
