On the other hand, chili powder is a blend of spices typically used in Tex-Mex and Mexican cuisines. It usually contains ground chili peppers along with other spices such as cumin, garlic powder, oregano, and salt. Chili powder is known for its earthy, slightly spicy flavor and is often used to season chili con carne, tacos, and other Mexican-inspired dishes.
Chinese crushed red pepper, also known as Chinese chili flakes, brings a bold, spicy flavor to dishes. These flakes are made from dried chili peppers and are widely used in Chinese cuisine to add heat and aroma to stir-fries, noodle dishes, and sauces. Chinese crushed red pepper varies in heat level, with some varieties offering a mild warmth suitable for enhancing flavors without overwhelming dishes, while others provide a fiery kick that intensifies the heat.
The degree of heat found within peppers, also called pungency or piquancy, is determined by how it measures on the Scoville scale, recorded in Scoville Heat Units (SHU).
The heat of peppers is measured using the Scoville Heat Scale, which ranks the heat of a given pepper in units known as Scoville Heat Units (SHU). Bell peppers of all colors register zero SHU, meaning they're not hot at all. Jalapeños are medium, measuring 2,500 to 8,000 SHU, while extremely hot chiles like habaneros or Scotch bonnets come in at 100,000 to 350,000 SHU.
