What are Jalapeño Peppers?
A Jalapeño pepper is a type of chili pepper named after Jalapa, the capital city of the state of Veracruz, Mexico. Typically green when immature, these peppers turn a vivid red when fully ripened (although they are usually harvested when they are still green). In terms of heat, they have a Scoville rating of 2,500 to 8,000, which makes them moderately spicy.
Jalapeños are a small to medium-sized pepper, typically measuring in around 2-4 inches in length. They are known for their tapered shape and smooth skin, and it is the seeds and veins inside that are the spiciest parts so removing these before cooking can reduce the heat level.
Known for their unique sweet and spicy taste, many Mexican dishes use Jalapeños, including tacos, nachos, and burritos. The highly versatile pepper is used in much more, though. From adding a kick to your pizza or burger to hot sauce and even in cocktails! When stuffed with cheese, they make a popular bar snack or appetizer.
What are Poblano Peppers?
A poblano pepper is a type of chili pepper named after the Mexican state of Puebla. Slightly larger than a jalapeño, they also have a distinctive conical shape with a much broader base. In terms of heat, they are also milder than jalapeños, with a Scoville rating of around 1,000 to 2,000.
Poblanos are usually dark green and grow up to six inches in length three inches wide before being harvested. As they mature, they begin to turn a reddish-brown, while their taste becomes sweeter and slightly hotter.
Their size and shape make them an interesting ingredient to work with. The large size means they are perfect for stuffing, but also means they can be easily sliced or diced for use in a range of dishes, developing a rich smoky flavor when roasted.
Perfectly complementing cheese and meat, poblanos are commonly used in soups, stews, casseroles, pasta dishes, and more. Unsurprisingly, they are a popular ingredient in Tex-Mex cuisine, featuring in everything from fajitas and enchiladas to quesadillas.
When selecting a poblano pepper, make sure you opt for ones that are firm and have a glossy, and unblemished surface. For a milder flavor, choose smaller poblanos, while for a spicier dish, look for the larger options.
What are the similarities between Jalapeño Peppers and Poblano Peppers?
Although there are clear differences between the jalapeños and poblanos, there are also some similarities. They are part of the Capsicum annuum species, which also includes other popular peppers such as bell pepper, cayenne, pimiento, and serrano. Both peppers can also be grown easily at home, responding well to a variety of soil types and conditions.
In terms of appearance, both are usually harvested when green, although they can also be left to ripen. They also have a similar conical shape that tapers to a point. However, poblano peppers generally grow larger, up to six inches in length, while jalapeños typically measure around four inches.
Another shared characteristic is their widespread use in cooking. Both are found extensively in Mexican cuisine, but have gained significant popularity in other parts of the world as home cooks and professional chefs look to add flavor and spice to everything from soups and stews to salads and sandwiches.
What are the differences between Jalapeño Peppers and Poblano Peppers?
While there are similarities, jalapeños and poblanos do differ significantly, particularly in terms of taste, heat, and culinary use.
The heat level is the most significant, with jalapeños measuring much hotter than poblano peppers, with a Scoville rating between 2,500 and 8,000 compared to 1,000 and 2,000. This means that Jalapeño peppers are spicier so might not be the most suitable pepper for those who prefer milder dishes.
Another significant difference is their flavor profile. Jalapeño peppers tend to have a slightly sweet and grassy flavor, while Poblano peppers are richer and earthier. This is why jalapeños tend to be used to add heat, while Poblano peppers are used to add depth and complexity.
Jalapeños are also commonly used in dishes such as nachos, tacos, and burritos, where their heat level can be cut through the richness of the cheese, beans, and meat. On the other hand, poblano peppers are used in dishes such as chiles rellenos or chiles en nogada.
These dishes allow other ingredients to be the star, particularly chiles en nogada which sees the poblano stuffed and then topped with a walnut-based cream and finished with a sprinkling of pomegranate seeds. In contrast, Jalapeño peppers are often pickled and used as a topping for burgers or sandwiches to add a spicy kick to the dish. The two peppers may look similar, but their distinct flavors and heat levels make them versatile ingredients in different meals.
