Discover the Wonderful World of Chili Peppers


For the ultimate spice-lover, there is nothing quite like biting into a perfectly ripe chili pepper to experience its heat and flavor. But before you take that bite, you should know there are differences between pepper varieties regarding heat and spiciness.

In this piece, we’ll investigate the realm of chili peppers and uncover some of the spiciest varieties around.

We’ll start by discussing what makes a pepper hot in the first place – spoiler alert; it’s all about capsaicin!

I’ll introduce you to a few varieties that pack a serious punch and those that are milder. There are many varieites of chili peppers. We will only address a few of the more popular varieties here and leave you to explore the rest.

Of course, no discussion of spicy food would be complete without mentioning the Scoville Heat Units scale. We’ll explore which chilis are highest on the scale?

Whether you love spice or are just wondering which variety of chili pepper will work best in the dish you plan to make, this blog post has something for everyone. Get ready to expand your knowledge – and maybe even your taste buds!

Habanero Peppers

Habanero peppers are considered one of the spiciest varieties, registering between 100k and 350k on the Scoville Heat Unit scale. Habaneros have a distinct fruity flavor with hints of citrus, making them popular in sauces and marinades.

For those seeking a fiery kick (and I mean firey), habaneros can be added to meals for an extra burst of heat.

For those wishing to cultivate their own peppers, like I do, ample sunlight and regular watering are essential for successful growth.

Chili peppers require plenty of sunlight, so make sure they get 6-8 hours per day during the summer months when they’re producing fruit. You should also water regularly as these plants don’t tolerate drought very well; aim for about 1 inch per week, depending on your soil type and climate conditions.

If you want big fruits, provide plenty of fertilizer throughout the season, which will help ensure maximum yields come harvest time.


Harvesting is fairly straightforward – simply wait until the pepper has reached its desired size before cutting it from the plant using scissors or shears; gloves are recommended, especially when harvesting habanero peppers due to their extreme heat.

To preserve the peppers (if they aren’t consummed soon after harvest), I will usually freeze them, which helps retain their flavor longer than other methods, such as drying or pickling.

I love cooking with habanero peppers because they bring intense flavor and an unexpected heat level, perfect for spicing up my dishes.

Whether adding some zestiness into homemade salsa (which I make every week) or giving chili con carne a fiery twist, whatever your preference, there is no denying that these little gems pack quite a punch.

I highly recommend trying a new recipe using habanero chilis but do so sparingly at first and taste as you go to make sure your dish isn’t too hot for your family or guests.

Habanero peppers provide a spicy punch to food but should be handled carefully due to their intense heat. I highly recommend gloves when working with habanero peppers or any pepper with a high SHU rating.

Moving on from habaneros, scotch bonnet peppers offer an even higher level of spiciness that can bring serious heat to your meal.

Key Takeaway: Habanero peppers are a popular chili pepper choice due to their fruity flavor and intense heat. They require plenty of sunlight and regular watering for optimum yields when harvesting at home, so spice up your next meal with some locally-sourced habaneros.

Scotch Bonnet Peppers

Scotch bonnet peppers are a type of chili pepper that is native to the Caribbean. This chili pepper packs a punch with its searing heat. The Scotch bonnet is renowned for its unique form and immense spiciness, ranging from 100,000 to 350,000 SHU – much hotter than jalapenos’ 2,500 SHU or habaneros’ 300,000. Similarly, jalapenos typically have around 2,500 SHU, while habaneros average about 300,000 SHU.

These peppers get their name from resembling a traditional Scottish tam o’ shanter hat with a flat top and downward-sloping sides. Due to their distinctive flavor, Scotch bonnets are often featured in Jamaican and other Caribbean dishes, such as jerk chicken or fish.

Scotch bonnets also add incredible flavor when added to sauces or marinades. The taste of these little beauties is unique, making them popular with chefs worldwide. They can be used in curries, stews, salsas, and hot sauces.

When handling these peppers, wearing gloves is essential since even touching your eyes after handling them can cause severe burning sensations. Start with a minimal amount of peppers until you become comfortable with their heat level. You can always add more later rather than risk ruining the dish by adding too much heat.

I’m not aware of any Mexican restaurants locally that serve dishes that include scotch bonnet peppers, but I would be the first in line to order.

Whether served fresh or dried and ground into powders, scotch bonnets make for an exciting addition to any meal that will tantalize your taste buds as no other pepper can.

The jalapeno pepper is another spicy addition to any dish with its bright green to yellowish-orange color.

Key Takeaway: Scotch bonnets are a popular chili pepper native to the Caribbean, known for their distinctive shape and intense heat. They’re widely used in dishes like jerk chicken or fish, as well as sauces and marinades.

Jalapeno Peppers

Jalapeno peppers are one of the most popular and versatile types of chili pepper. They have a zesty taste, with Scoville Heat Units ranging from 2,500 to 8,000. On the Scoville scale, they measure between 2,500 and 8,000 SHU (Scoville Heat Units). That makes them significantly milder than Habanero or Scotch Bonnet peppers but still spicier than Serrano or Poblano peppers.

Mexican cuisine has long utilized these bright green chilies to bring a zesty kick to salsa, guacamole, and tacos.

They can also be eaten raw as part of salads or sandwiches or pickled in vinegar for added tanginess.

For those who prefer less heat, jalapenos can be blanched before adding them to recipes – this process reduces their spiciness while preserving their delicious taste.


I have never blanched jalapenos, as I like more of a kick to my salsas and dishes. I will remove the seeds and ribs inside the pepper for those who can’t take the heat.

Jalapenos can be found in almost any dish in Mexican restaurants and are also used in Indian cuisine.

Again, to ensure safe handling, gloves are recommended when handling jalapenos due to the potential for skin irritation from their oils.

The oils will stick to your hands long after you have prepared your dish. An accidental rub to the eye could result in a painful experience. I usually wash my hands with white vinegar after handling hot peppers. This helps to remove any residual oil.

I always have jalapenos on hand. They are a staple in my refrigerator or canned in my pantry. I use them in egg dishes, salsas, pinto beans, enchiladas, hot sauce, and in cabbage slaw for topping on tacos and tostadas. Try adding some diced jalapeno peppers to your next dish.

I love to grill fresh jalapenos and add them as a side to my chicken or beef enchiladas (or even a steak dinner–they are great with anything). I also pickle jalapenos with onion and spices for a great sandwich accompaniment.

Then we come to serrano peppers that offer a zestier taste than jalapenos, with an extra kick of heat.

Serrano Peppers

Serrano peppers are a popular variety of chili pepper that has a mild to medium heat level. Measuring between 10,000 and 23,000 SHU on the Scoville scale, they offer a great balance of flavor and spice for those looking to add some kick to their dishes.

The serrano is a popular choice for adding flavor and spice to dishes and is plentiful at most US supermarkets, especially in the southwest.

When eaten raw, serranos have an earthy flavor with hints of citrus and black pepper. By themselves, they will not overpower a dish. When cooked, they develop sweet notes with a bit more heat than when consumed raw.

I add serranos to all my dishes and often combine them with jalapenos, ghost peppers, and habanero peppers to add dimension and complexity to my southwestern dishes.

The ghost pepper is the spiciest on the Scoville scale at 800,000-1,001,300 SHUs. If you are looking for a challenge, trying a recipe with ghost peppers would be at the top of the list.


Enjoy serrano peppers in all sorts of local dishes, such as tacos al pastor or enchiladas verdes made with freshly harvested chilies from nearby farms.

For an authentic experience, why not sample the local fare featuring serrano peppers in Prescott? Trot off to the Farmer’s Market, and you’ll find them there.

Serrano peppers have a medium-high heat level and complement other varieties of peppers as well, such as red or green bell pepper, which have a SHU of zero on the Scoville sale.

Now let’s look at another favorite of mine, Poblano Peppers, which offer a milder yet still flavorful taste.

Key Takeaway: Serrano peppers are a popular chili pepper with a mild to medium heat level that adds flavor and spice to dishes. Raw Serrano peppers boast an earthy taste with zesty and peppery undertones, making them the perfect addition to any dish without overwhelming other flavors. Prescott has many restaurants serving classic recipes like tacos al pastor or enchiladas verdes made with freshly harvested chilies from nearby farms.

Poblano Peppers

Poblano peppers are a mild to medium-hot pepper variety that measures between 1,000 and 2,500 SHU on the Scoville scale. They have a deep green color with thick walls, making them perfect for roasting or stuffing.

Poblanos are common in Mexican dishes, such as chili rellenos and mole sauce. When dried, they become known as ancho chiles, often used to add smoky flavor to sauces and soups.

The poblano pepper has a unique taste which is comprised of sugary, earthen notes with a mild kick. Its gentle heat level also allows it to blend well into dishes without making them too spicy for those who don’t enjoy intense heat levels from their food.


When selecting poblano peppers at the grocery store, look for smooth skin free of blemishes or wrinkles since this indicates freshness. Avoid any peppers that feel soft or limp since these may not taste as good when cooked up later on down the line.

Poblano peppers are excellent to add to fresh salsa. I also roast them with jalapenos, serranos, habaneros, tomatoes, and garlic and blend them into a sauce for pork and beef roasts in the pressure cooker. The flavor of this combination of peppers for a sauce will knock your socks off.

Poblanos are excellent in tacos and enchiladas, providing some kick without being too spicy for kids.

Key Takeaway: Poblano peppers are a popular and versatile chili pepper used in Mexican cuisine, providing sweet and earthy tones with mild heat. They are commonly found in dishes such as chili rellenos or mole sauce, making them an excellent choice for authentic southwestern flavors without the overwhelming spiciness.


Chili peppers offer an array of flavors and heat to any culinary creation, ranging from the mild poblano to the blazingly hot habanero.

There are many other chili pepper varieties other than what is described in this blog post. From mild to fiery, there is a chili pepper for every palate.

Be sure to know the heat level of each variety of chili pepper before adding them to your recipes so you don’t end up with a surprise.
