Prik Ban Chang

Prik ban chang are known for their mildness and they generally have a Scoville score between 30,000 and 60,000 Scoville Heat Units (SHU). They are grown in the Ban Chang district of Samut Songkhram, which is why they are called Ban Chang peppers.

Although they are now grown in Ban Chang, they are initially from South America, the original location of all chili peppers.

Prik Ban Chang has an oblong shape and smooth skin, and usually grows to be slightly larger than a prik mun, often growing to be 5 to 7 inches (13 to 18 cms) long. Prik Ban Chang has a mildly spicy, peppery taste that contains hints of freshness and the pepper generally weighs around 1.23 ounces (35 grams). While they have red or green skin, depending on their ripeness, the green prik ban chang is often milder than the red one.

Sundried prik ban chang is a popular snack and garnish for stews, rice, and soups. Since they do not have many seeds, they are also used in curries and chili pastes.
