Sizzle is the best part of the burger. But it’s limited to side A and side B. In-between lurks the granular middle — it’s a lot of ground to cover.

Solved by the genius of math. Remember geometry’s plane — the way it’s all surface, no depth? Applied to the burger it produces infinite sizzle.

Here’s how to work the equation: Divide ground beef by two, roll each half into a sphere and, in a hot pan, smash with a spatula. The flattened patty plane browns to a sizzle on side A, sizzle on side B — no middle. Stack patty 1 on patty 2, sandwiching a slice of American cheese.

The result is a four-sided burger with a molten core. How’s that for higher math?



Prep: 10 minutes

Cook: 1 minute

Makes: 1 serving

Note: This burger doesn’t hold — make one at a time.

1 hamburger bun (preferably a Martin’s Potato Roll)

Butter, softened

Fixin’s — mayo, mustard, ketchup, onion, tomato, etc.

4 ounces ground beef chuck or other ground beef (not lean)

Kosher salt and freshly ground black pepper

1 1-ounce slice American cheese

1. Toast: Spread inner faces of the bun with butter. Heat a skillet or griddle over medium. Toast bun, butter-side down, until golden, 1-2 minutes.

2. Prep: Set the bun on a plate, open-faced. Pile fixin’s of choice on the bottom bun.

3. Roll: Divide beef and roll into two 2-ounce balls. Heat a dry skillet over medium-high.

4. Smash: When skillet is very hot, add the 2 beef balls. Immediately smash each with the back of a stiff metal spatula (use some muscle), creating two very thin patties, each a little wider than the bun. Season each with salt and pepper. Cook until browned on the bottom and a mottled gray/pink on top, about 45 seconds.

5. Flip: Scrape up and flip both patties. Top one with cheese. When the patty bottoms have browned (about 15 seconds) stack the patties so that the cheese is sandwiched in-between. Slide this cheese-filled burger onto the prepared bun. Close bun, squish gently. Burger perfection is yours.
