What is Jalapeno?

Medium-sized, mild to moderately hot chile peppers called jalapenos (pronounced “hal-a-PAY-nyo”) flavor everything from salsa to chili to salad dressing. The state of Veracruz in Mexico has the earliest cultivation records, and the term “jalapeo” is derived from Xalapa, the state’s capital. Although they are still frequently linked to Mexican food, they are now grown worldwide and can be found in fusion dishes from the American South to Asia and Africa.


The majority of jalapenos are deep green and only reach a length of 2 to 3 inches. Some mature and change color to red, purple, or other striking hues. Some peppers are hotter than others. These tiny firecrackers are blazing with health advantages no matter how you cut them. In addition to canned, sliced, and pickled items in the grocery aisles, you may get them fresh and whole in the produce department.

What is Jalapeno?

Capsaicin, a chemical substance abundant in the pithy white ribs of a pepper, gives jalapenos, a member of the nightshade family that also includes tomatoes, eggplant, and potatoes, their heat. Like most hot peppers, Jalapenos fluctuate in heat depending on various growing conditions, including sunlight exposure and soil pH. The Scoville scale measures the spiciness of pepper in Scoville units, and jalapenos range from 2,500 to 8,000. They are most frequently used in Mexican food, with a heat level between poblanos and habaneros, and are typically among the least priced fresh peppers at the grocery store.


Jalapeno peppers have a front-of-mouth hot impact and a vegetal flavor akin to green bell pepper. Individual peppers can vary greatly in terms of heat. Jalapenos are typically utilized in their unripe form after being plucked green. On and off the plant, jalapenos turn red as they ripen. Although the heat does not increase as they ripen, the flavor does get a little fruitier and less grassy.

How Hot are Jalapenos?

On the Scoville scale, jalapenos range from 2,500 to 8,000, which is greater heat than poblanos (1,000-1,500 SHU) and bell peppers but less heat than Fresno peppers (2,500 to 10,000 SHU) (0 SHU).

Compared to hotter peppers like serrano peppers (10,000–23,000 SHU), cayenne peppers (30,000–50,000 SHU), and habanero peppers (100,000–350,000 SHU), and ghost peppers, jalapenos aren’t very spicily hot (855,000–1,041,427 SHU).

Jalapenos and many other peppers’ heat levels vary depending on when in the growing season they are harvested, which contributes to their wide range on the heat scale (heat and rain also have an effect). Probably accustomed to seeing dark green jalapenos at the supermarket: These are harvested before fully mature and have a milder flavor.

On the other hand, red jalapenos have had more time to ripen fully and are slightly hotter. These are the red, ripe peppers needed to manufacture smoke-dried chipotle chiles.

How to Cut Jalapenos?

Here are the ways to cut jalapenos:

  1. Break off the stem of the jalapeño and discard it.
  2. Wash the pepper under cold water.
  3. With a small, sharp knife (such as a paring knife), halve the pepper lengthwise.
  4. If desired, shake out the seeds and use the knife’s point to scrape out the placenta and pithy “ribs” on the sides of the pepper.
  5. Slice or chop the jalapeño according to your recipe.

When working with jalapenos, avoid touching sensitive areas like your eyes, nose, mouth, or skin because they can sting like all spicy peppers. Capsaicin, a substance that activates heat and pain receptors, is what gives off that searing feeling. It may be found on the pithy pepper interior, where the seeds attach, in the seeds, inner fruit wall, and even the stems and leaves of the jalapeo plant.

To lessen the heat, you can remove the placenta and seeds, which many jalapeo recipes already require for textural purposes. When chopping jalapenos, consider wearing rubber gloves for added safety. Whether you’re wearing gloves or not, wash your hands often. Dish soap and hot water should be used to clean knives, cutting boards, and other surfaces.

How to Use Jalapenos?

Mildly hot jalapenos can be cooked in countless ways, whether you’re creating jalapeo poppers for the Super Bowl or adding some spice to your guacamole:
  • Pickle: It’s really simple to create your pickled jalapenos, though you’ve seen canned versions at a Mexican grocery store. Slice thin rings from a whole, fresh jalapeo while holding it by the stem. Place in a container, add a brine of white vinegar, water, and salt, and put the container in the refrigerator. Use to garnish tacos, nachos, and other dishes that could benefit from a touch of acidic heat.
  •  Stuff: An excellent party snack is stuffed jalapenos. Try goat cheese or a combination of sharp cheddar, jack, and cream cheese for stuffing jalapeo halves. After topping with breadcrumbs, arrange the stuffed peppers on a baking sheet. Place there and bake until crisp under the broiler.
  • Grill: When jalapenos are grilled, some of their sweetness comes out. Grill entire peppers until softened and thoroughly charred, brushing the grill with olive oil or cooking spray as needed. (Alternatively, place the peppers under a broiler or a gas flame.) Peel off the burned outer skin of the peppers after allowing them to cool to room temperature. Peeled, carefully chop the grilled jalapeo for a delicious guacamole. In the meantime, mash an avocado with salt, garlic powder, and lime juice. Add some chopped fresh cilantro and the chopped jalapeo to the mixture.

How Healthy is Jalapeno?


Vitamins A and C, as well as potassium, are abundant in jalapenos. They also contain folate, vitamin K, B vitamins, and carotene, an antioxidant that may help prevent cell damage.

Their health advantages are largely due to a substance called capsaicin. The peppers are spicy because of this.

Longer Life

According to one study, those who consumed spicy peppers regularly were 13% less likely to pass away throughout the 19-year study than those who consumed little to no peppers. The ability of capsaicin to increase blood flow and combat fat, according to researchers, may be a factor.

Pain Relief

The natural painkiller capsaicin works best when applied topically to the skin. This does not imply that you should rub some jalapenos on your body. That burns, as anyone who has done it knows. Use lotions, ointments, or patches containing capsaicin if you desire the compound’s pain-relieving properties. You may take capsaicin if you have pain from arthritis, aching muscles, or nerve issues.

Weight Loss and Blood Sugar Control

You may have heard that eating spicy food can aid in weight loss. Consuming chili peppers before a meal high in carbohydrates may also assist in lowering blood sugar levels. While eating peppers consistently can boost metabolism, aid in fat loss, and reduce hunger, they are not a miracle weight-loss food.

Fights Infection

Jalapenos include a variety of bioactive substances and vitamins that have the potential to be very effective at inhibiting the growth of foodborne bacteria and yeast. Additionally, several pieces of data have demonstrated that jalapenos’ potent antibacterial properties aid in preventing chlamydia infection, dental decay, and strep throat. The effects of this foodborne infection can be lessened by jalapeño extracts, which prevent the cholera bacteria from generating toxins.

Augments Heart Health

Jalapenos enhance blood circulation and widen blood vessels because they contain significant amounts of vitamins C, A, and bioflavonoids. Additionally, it aids in blood pressure control and reduces the risk of atherosclerosis, heart attacks, and strokes. Bad cholesterol levels are said to be reduced by capsaicin annually, and platelet aggregation is also said to be reduced.

Possible Side Effects and Precautions

Although eating jalapenos is linked to several positive health impacts, there are also some potential negative effects.

The most frequent adverse effect is a brief burning feeling in the mouth following meals. This response might be minor to severe, depending on how hot the chili is.

Taking a few steps will lessen reactions to jalapenos for those with a low tolerance for spicy foods.

  • Avoid scarring: Look for smooth jalapeño peppers without small brown lines, as scars indicate a spicier pepper.
  • Use gloves: Wearing gloves when handling peppers can prevent transferring the spicy compounds to other sensitive areas of your body, like your eyes.
  • Remove membranes: Remove the white membranes inside the jalapeño before cooking with them since the membranes have the highest concentration of capsaicin.
  • Drink milk: If the burning sensation becomes too strong, drinking full-fat cow’s milk can help temporarily reduce the pain.

Those with reflux may avoid jalapenos if they experience heartburn symptoms because at least one study has shown that capsaicin can worsen it.
If hot chilis are not a frequent component of their diet, people with irritable bowel syndrome may also feel unpleasant symptoms after eating them. Abdominal discomfort, burning, cramping, and diarrhea are typical adverse effects.

Where to Buy Jalapenos?

One of the most popular types of chili peppers in American grocery shops is the jalapeo. Fresh jalapenos should be brilliant green, firm, and smooth when picked, usually between two and four inches long with the stem firmly attached. You may typically locate chile peppers on display with bell peppers in the produce area.

A hotter pepper may have white striations close to the end of the stalk. They may change color as they age, going from green to red and seeming slightly shriveled. Avoid peppers that are mushy or have a stem that is loose or absent.

At Mexican grocers or in the Mexican foods area of most grocery shops, you can get smoked and dried whole jalapenos, known as chipotles, and dry jalapenos that have been ground or crushed. Additionally, you may buy them fresh at farmers’ markets, where you could find uncommon types, as well as from bulk merchants and internet grocers. You might also think about producing your jalapenos at home if you have access to a warm place with continuous, direct sunlight.

Storage Tip

Fresh jalapenos can be kept in your refrigerator’s crisper drawer for up to a week by placing them in a paper bag or wrapping them in paper towels. Jalapenos can be chopped first and frozen in individually portioned packages, whole in plastic freezer bags or airtight containers; for maximum quality, use within three months.


Fruits like jalapenos are adaptable and healthy, and there are many ways to enjoy them. They include capsaicin, a chemical that probably explains many health advantages, such as the reduced risk of ulcers, enhanced heart health, and pain relief. Although they are generally harmless, some people may experience fast-mouth burning and unpleasant digestive side effects. Jalapenos can be a beneficial addition to your diet if you like spicy cuisine and don’t have any negative side effects. Jalapenos can be a healthy addition to your diet plan that provides extra flavor and nutrition if you enjoy spicy foods and do not experience any adverse effects.
