Cup and Char Pepperoni: How to Get Those Crispy Little Cups at Home

You have seen the photos. A pizza covered in tiny curled bowls of pepperoni, each one with a blackened rim and a little pool of red oil in the middle. Then you make pepperoni pizza at home and every slice lies there flat as a coaster.

Cup and char pepperoni is a specific product, sliced a specific way, baked a specific way. Get those three right and the cups show up. Miss any one of them and you are back to coasters.

I went through the meat-industry trade press, Hormel's own product specs, a pizza reviewer's 11-brand cupping test and the well-known thickness experiments to figure out which parts actually matter. Here is what I found, and how to use it on a Friday night.

What Cup and Char Pepperoni Actually Is

Cup and char is a name for pepperoni that curls into a bowl as it bakes and chars at the rim. You will also see it sold as cupping pepperoni, old world pepperoni or, if you hang out on pizza Instagram, roni cups.

Hormel's foodservice spec for Rosa Grande Cup and Char pepperoni gives a good picture of what the product looks like on paper. It is a pork and beef pepperoni in collagen casing, 32 mm (about 1¼ inches) across, sliced to an exact 16 slices per ounce. That is smaller across and thicker than the silver-dollar slices on most chain pizzas.

Flat, pre-sliced deli pepperoni is the khaki pants of pizza toppings. Inoffensive, everywhere, and nobody has ever posted a photo of it. Cupping pepperoni is the opposite, which is a big part of why it took off.

Why Some Pepperoni Cups and Some Lies Flat

Three things work together here, and the clearest explanation comes from the meat industry itself. In a 2020 piece for MEAT+POULTRY, Donna Berry explains the curl like this: the edges of the slice curl up toward the heat source and cook before the center does, while cheese and dough insulate the bottom and keep the middle flat.

Heat comes from above, the slice shrinks from the top, and the edges lift. The same piece adds that the casing should shrink quickly, so the edges can rise before the slice gets locked in place. Even the way the meat flows into the casing during stuffing affects the curl.

The thickness numbers most people quote come from food writer J. Kenji López-Alt's experiments. As Tasting Table summarizes his findings, the top of each slice gets more heat than the bottom, natural or collagen casing curls better, and the ideal thickness sits between 0.1 and 0.225 inch.

So why did flat pepperoni take over?

History, mostly. A 2019 Wall Street Journal story reposted by Hormel explains that the original pepperoni was made in natural casings left on during slicing, and those casings contracted in the oven so the slices puckered.

After World War II, makers chasing efficiency switched mostly to paper-like fibrous casings that were peeled off before slicing. No casing, no curl. Lay-flat became the national norm for decades, while cupping hung on in holdout markets like Buffalo and Detroit. You can read more about those regional pies in my guide to popular pizza styles.

Casing: The First Thing to Check

If you only remember one thing from this page, make it this. The casing is the engine of the cup. Here is how the three common types compare, based on MEAT+POULTRY's casings primer and the cupping sources above.

The practical test is easy. Look at the edge of a slice or the outside of the stick. If you can see a thin skin around the rim, you are in business. If the stick came out of a peel-off wrapper and the meat goes right to the edge, expect coasters.

The same WSJ story notes that some cupping products carry slightly more sugar to encourage charred edges, and some makers stuff their casings in proprietary ways to help the curl. So two natural-casing sticks can still behave differently. For a deeper look at what goes inside the casing, see my explainer on what pepperoni is made of.

Slice Thickness: The ⅛-Inch Sweet Spot

Even the right stick will not cup if you slice it wrong. MEAT+POULTRY puts the problem plainly: too thin and the whole slice curls, too thick and the slice is too heavy to lift. The exact sweet spot depends on how dense the pepperoni is.

Food Republic's guide to slicing for cups lands on the same 0.1 to 0.225 inch window, and explains the logic: a thicker slice widens the temperature gap between top and bottom, but go too thick and it gets too stiff to curl.

Use a sharp chef's knife and slice it yourself. A whole stick lets you hit that window. A bag of pre-sliced pepperoni has already made the decision for you, and it is almost always too thin.

What an 11-Brand Cupping Test Found

I have not lined up 11 pepperoni sticks in my own kitchen, but somebody did. Jim Mirabelli of NEPA Pizza Review bought pepperoni from supermarkets, big-box stores and Amazon, sliced them and baked each on an 11-inch pie with the same sauce and Grande whole-milk mozzarella. His pepperoni power rankings scored each one for cupping and taste.

Two things jump out. Most sticks cup reasonably well when you slice them yourself, including brands that never put cup and char on the label. And taste and cupping are separate scores. Foustman's barely cupped but scored 8.1 for taste, and Mirabelli notes its edges still curled and crisped.

Where to Buy It

Availability is the annoying part. Mirabelli writes that true cup and char is hard to find in many areas, and that pizzerias often buy it in 25-pound cases. Back in 2020, PMQ reported Buffalo pizzerias stressing over a cup and char shortage, with one owner calling it definitely a hallmark of Buffalo-style pizza.

Here is where I would look, in order:

• The deli counter or specialty meat case. Look for whole sticks in natural or collagen casing. Old world on the label is a good sign, but check the edge for skin anyway.
• The packaged pepperoni aisle. Hormel launched Pepperoni Cup N' Crisp in 2020 as a retail cupping product, in original and bold, sized at one 5-ounce package per pizza. The launch announcement says to lay it over the cheese and bake as usual.
• Your local pizzeria. If a shop near you serves cupping pepperoni, ask whether it will sell you some. Worst case, they say no and you buy a slice for research purposes.

Expect to pay a little more. The Hormel-reposted WSJ story put cupping pepperoni at about 15 percent more than lay-flat, partly because it takes more time to produce.

How to Bake for Maximum Cups

Pepperoni goes on last, on top of the cheese. Hormel's spec says the same thing for its cup and char. Tuck slices under the cheese and you insulate the top, which is exactly the side that needs to shrink.

Then give it heat. Thursday Night Pizza ran the same pepperonis on two pizzas. On a pan at 500°F, old world pepperoni cupped nicely and the American-style stick only curled a little at the edges. On a stone preheated at 550°F for an hour and finished under the broiler, the old world slices cupped gorgeously and even the pre-sliced kind baked into shallow bowls.

That lines up with the mechanism. Top heat lifts the edges, so a broiler finish is your friend. If your oven tops out lower, a preheated stone or baking steel plus the broiler for the last minute or two gets you most of the way. My breakdown of the best oven settings for pizza at home covers which setting to use for each step.

The Cup-and-Char Method, Step by Step

The Grease Question

Those little pools of oil are the whole point for fans, and the whole problem for critics. USDA nutrient data for sliced beef and pork pepperoni lists 46.3 grams of fat per 100 grams. By my arithmetic, a 5-ounce pile of slices carries about 66 grams of fat, and a lot of it melts out in the oven.

Cups catch that fat. Flat slices let it run. MEAT+POULTRY calls the cup a grease chalice, and that is a fair description. On a flat-pepperoni pie the same fat drifts across the cheese.

The catch is spills. In the WSJ story, Paulie Gee's founder Paulie Giannone called high-volume cupping pepperoni unmanageable, because cups tumble off and dump their oil. So go generous, but do not build a pepperoni Jenga tower. If you are watching salt, that same USDA entry lists 1,582 mg of sodium per 100 grams, and my guide to low sodium pizza has ways to balance it out.
