Round Peppers Guide: From Marble-Sized to Apple-Wide

Peppers come in a surprising number of shapes. Most are cones, long and thin, or curved, but plenty of chilies buck the trend. Round peppers are more common than you’d think, and you’ll find them all along the pepper scale. Some are ornamental peppers that hang on the plant like Christmas bulbs, while others are culinary chilies that look more like an apple or a tomato than a hot pepper. Here they are, from sweet pimentos with barely any heat to the Dragon’s Breath, with what each one looks like, how hot it is and how to use it.

What counts as a round pepper?

Before we start, here’s what we mean by round. Marble-shaped counts, and so does a bulb that’s rounder than it is cone-shaped. Anything shaped like a tomato, an apple or a pumpkin is in, too. A cone with rounded edges isn’t, since we have to draw the line somewhere. A couple of oval peppers, the pequin and the Peruvian white habanero, made the cut because they’re closer to a bean than a cone.

Mild round peppers

These bring the shape with little or no burn, so they’re easy for you to cook with and easy on anyone at the table.

Pimento peppers

The pimento pepper is the round, red pepper you’ll find stuffed into green olives, and it’s also known as the cherry pepper for its shape. Some say it looks more like a heart. It’s sweeter than a bell pepper, with heat that barely registers, so it’s an easy swap when you’d like something different. You’ll find pimentos pickled, canned and diced, and they’re the pimento in pimento cheese.

Ñora peppers

The ñora is a small, round Spanish pepper, a little flattened and usually 1 to 2 inches across. It’s picked fully ripe and dried in the sun, and it turns a deep, almost burgundy red with wrinkled skin. The flavor’s sweet, earthy and lightly smoky, with very little heat. It’s grown mainly in Murcia and Valencia, and you’ll see it in many traditional Spanish dishes.

Peppadew peppers

The Peppadew looks like a cherry tomato, and that round shape makes it great for stuffing. Peppadew is a trademarked name for sweet piquanté peppers grown in South Africa’s Limpopo province. They’re sold seeded and pickled in a sweet and sour brine, so the tang tends to win out over the pepper’s own sweetness. Stuff them with cheese, or slice them onto sandwiches and pizza.

Cascabel peppers

Cascabel means “little bell” or “rattle” in Spanish, and when you shake a dried cascabel pepper, its seeds rattle inside. It’s also called chili bola, or ball chili, since it keeps its round shape whether it’s fresh or dried. It’s about 1 to 1½ inches across, and you’ll usually find it dried, in deep browns with swirls of red. The flavor’s earthy and nutty, which suits rustic cooking.

Medium round peppers

These run from just under a jalapeño’s heat up to a cayenne’s, so they’ve got some kick.

NuMex Centennial

The NuMex Centennial is an ornamental pepper from New Mexico State University, named for the university’s centennial. Its pods are about an inch long and bulb-shaped, tapering to a point, and one plant carries them in purple, yellow, orange and red all at once. There isn’t much nuance to the flavor, which is bright with a little bitterness, but it’s edible, and it adds color to salads and soups. For the same look with more heat, try its cousin, the NuMex Twilight.

Cherry Bomb peppers

With its cherry shape, the Cherry Bomb pepper is an easy pick for this list. It’s a hybrid, about 2 inches long, plump and round with thick walls. Don’t let the name fool you. It’s about as hot as a milder jalapeño, and it’s sweet. Those thick walls make it terrific for stuffing and pickling, so try it in place of jalapeños in your favorite popper recipe.

Black Pearl peppers

Like little black marbles, the Black Pearl pepper is an ornamental standout. The plant’s leaves are deep purple to black, and its half-inch to 1-inch pods start onyx black and ripen to crimson red. There’s more heat than you’d expect, on par with a serrano, and the red ones are the hottest. The flavor’s light, slightly sweet and citrusy. They’re too small to stuff, but you can chop them into a salsa for a dramatic look.

Manzano peppers

Manzano means “apple” in Spanish, and the manzano pepper looks like a golf ball-sized apple. It ripens to yellow-orange or, in another variety, red. Cut one open and you’ll see black seeds, a mark of its species, Capsicum pubescens. It’s about four times as hot as a jalapeño, and its fruity, citrusy flavor and thick walls make it a superb salsa chili. It’s native to the cool Andes and hard to grow outside that kind of climate, so it can be tough to find outside Mexico and South America.

Aji charapita

Forget marbles: the aji charapita is the size of a pea, about a quarter inch across. It comes from the jungles of northern Peru, where it’s mostly grown wild, and it ripens to yellow. That tiny pod is as hot as a cayenne pepper, with a fruity, tropical flavor like a habanero. In Peru, it’s often crushed with a fork or spoon over rice, fish and chicken as a finishing spice.

Pequin peppers

The pequin pepper is less than an inch long and oval, shaped more like a grain of rice than a marble, so it’s a borderline pick. It’s often confused with the chiltepin, and both get called bird peppers. Ripe red pequins are smoky and a little nutty, with some fruit and citrus, and their heat can run past a cayenne’s. It’s one of the peppers in Cholula hot sauce.

Extra-hot round peppers

Here’s where the heat gets serious. Most of these start around a cayenne’s heat, and the hottest go well past a habanero’s.

Dundicut peppers

You’ll usually find the dundicut pepper dried, and in that form it looks like a red berry: round, wrinkled and about half an inch across. Fresh, it’s teardrop-shaped and about an inch wide. It’s a staple chili in Pakistan, where it heats up curries, chutneys and sauces. The flavor’s lightly fruity with a sun-dried bitterness, and its heat starts above the hottest cayenne.

Rocoto peppers

Like the manzano, the rocoto pepper is a Capsicum pubescens, with the same black seeds and a plant with hairy leaves. It can look like a small tomato, an apple or a pear, and it’s thick-walled and juicy inside. Its heat range is one of the widest around, from a mild cayenne up toward a mild habanero, behind a sweet, fruity and grassy flavor. It’s a must in Peruvian and Bolivian cooking, in pastes, salsas, hot sauces and stews. In Arequipa, Peru, rocotos are stuffed for rocoto relleno, and they’re boiled first to take out some of the heat.

Prairie fire peppers

Like the NuMex Centennial, the prairie fire pepper is an ornamental with bulb-shaped pods about an inch long, and they look like Christmas lights. One plant can carry green, purple, cream, yellow, orange and red pods at the same time. The big difference is heat. It’s about as hot as a Thai pepper, and it’s got more flavor than most ornamentals, with a fruity, tangy undertone. Chop it into a salsa and you’ll have the most colorful one you’ve ever made.

Chiltepin peppers

The chiltepin is tiny and round, under half an inch across, and it grows wild in the Southwestern U.S. and northern Mexico. It’s smoky and earthy, and its heat starts where the hottest cayenne stops, so it can be a good deal hotter than a pequin. It’s been harvested from the wild for generations, and it’s still used in salsas, sauces, soups and stews in Mexican and Southwestern cooking.

Peruvian white habanero

Shaped like a little jelly bean, the Peruvian white habanero grows up to 2 inches long but only about three-quarters of an inch wide, so it’s more oval than round. It ripens from green to pale yellow or creamy white. The pale color doesn’t mean less heat. It’s as hot as an orange habanero, with the same fruity flavor and a hint of smoke, and it makes a pretty ornamental plant, too.

Wiri wiri peppers

The wiri wiri pepper looks like a little cherry, about half an inch across, and it ripens from green to yellow, orange and red. Its heat rivals a habanero or a Scotch bonnet, and its flavor’s fruity with a tomato-like tang. It’s a staple in Guyana, where it goes into a spicy mango table sauce and into pepper rum that’s used to finish stews and soups.

Roatan pumpkin habanero

The Roatan pumpkin habanero comes from Roatán, an island off Honduras. It’s a plumped-up habanero, up to about 3 inches long, and most are rounded and creased like a little pumpkin, ripening from green to peach to orange. It can get hotter than a common habanero, up to 500,000 SHU, which puts it close to the Red Savina. The flavor’s fruity and nearly citrusy, so it’s a good fit for fruit-based salsas and hot sauces.

Super-hot round peppers

Only one round pepper makes it up here. At this level there’s enough capsaicin to hurt, so wear gloves and eye protection when you handle it, and know how to cool chili burn.

Dragon’s Breath pepper

The Dragon’s Breath pepper was grown in Wales and made headlines in 2017. It came out of a trial of a new plant food involving researchers at Nottingham Trent University, and it’s named for the Welsh dragon. It was reported at 2.48 million SHU, which would have beaten the Carolina Reaper, but Guinness World Records never confirmed it. The record went to Pepper X in 2023, at 2.69 million SHU. The researchers suggested that because the pepper numbs the skin, its oil could be useful as an anesthetic for people who can’t have the usual ones. Early photos showed small pods, about half an inch across.

Which round pepper should you use?

It depends on what you’re cooking and how much heat you want.

• For stuffing: Pimentos, Peppadews and Cherry Bombs, or rocotos if you want serious heat.
• For salsa: Manzano or rocoto for fruity heat, or wiri wiri or Roatan pumpkin habanero if you want it extra hot.
• Dried: Cascabel, ñora or dundicut, which you’ll usually find dried anyway.
• For the garden: NuMex Centennial, Black Pearl or prairie fire, all ornamentals you can eat.
