The Heat Scale: Scoville Units Explained

To understand how spicy a pepper is, we refer to the Scoville scale, which measures the concentration of capsaicin — the compound responsible for heat. Below is a handy comparison chart:

Pepper Scoville Heat Units (SHU) Flavor Profile

Jalapeño 2,500–8,000 Grassy, crisp
Guajillo 2,500–5,000 Berry-like, slightly sweet
Ancho 1,000–2,000 Smoky, sweet raisin
Habanero 100,000–350,000 Fruity, floral
Serrano 10,000–23,000 Peppery, tangy
Cascade 30,000–50,000 Clean heat, vegetal
Chipotle 5,000–10,000 Smoked, bold
Chiltepin 50,000–60,000 Wild, intense
Pasilla 1,000–2,500 Dark fruit, chocolate tones

How to Store and Prepare Mexican Peppers

Proper storage and preparation can preserve the flavors and extend the shelf life of your peppers. Here are some practical tips:

  • Storage Tips:
    • Fresh peppers can be refrigerated in a paper bag for up to two weeks.
    • Dried peppers should be kept in an airtight container in a cool, dark place.
    • Freezing whole jalapeños or poblanos is a great way to preserve flavor for months.
  • Preparation Techniques:
    • Roasting peppers over an open flame brings out their natural sugars and enhances depth of flavor.
    • Soaking dried peppers in warm water softens them for sauces and pastes.
    • Removing seeds and membranes reduces heat intensity significantly.
