Everything You Need to Know About Growing and Using Hot Peppers

Hot peppers—commonly called chillies in the UK—aren’t just about spice. Each variety brings its own flavour, aroma, texture, and culinary power. These Capsicum plants have been cultivated for thousands of years and are now eaten by over a quarter of the global population daily. And best of all, they can thrive right here in the UK!

How to Grow Chilli Peppers in the UK

  • Start seeds indoors between January and March for best yields
  • Transplant to a heated greenhouse or sunny sheltered spot after frost
  • Water regularly and feed during flowering and fruiting
  • Perennials if overwintered indoors, or grow as annuals outdoors
  • Ideal for containers, conservatories, greenhouses, or polytunnels

With proper care, even super-hot chillies like the Habanero or Thai Bird’s Eye can flourish on UK soil.

Understanding the Scoville Heat Scale (SHU)

The Scoville Scale, created in 1912, measures chilli heat by how much dilution is needed before the pepper's heat is undetectable.

Pepper Name Level Scoville Heat Units (SHUs)
Anaheim, Peperonicini, Cherry Level 1 100-1,000 SHUs
Coronado, Sangria Level 2 1,000-1,500 SHUs
Ancho, Poblano Level 3 1,500-2,500 SHUs
Hatch Green Level 4 2,000-5,000 SHUs
Rocotillo Level 5 2,500-5,000 SHUs
Serrano, Jalapeño, Mirasol Level 6 5,000-15,000 SHUs
Chipotle Level 7 15,000-30,000 SHUs
Manzano Level 8 30,000-50,000 SHUs
Cayenne, Tobasco Level 9 50,000-100,000 SHUs
Thai Level 10 100,000-350,000 SHUs
Habanero, Chocolate Habanero, Scotch Bonnet, Orange Habanero, Jamaican Hot Level 11 350,000-855,000 SHUs

Safety First: Handling Hot Peppers

Capsaicin triggers your body’s heat receptors but doesn’t actually burn tissue. Still, when preparing hotter chillies:

  • Wear gloves to avoid skin irritation
  • Don’t touch your eyes after chopping
  • Wash hands and surfaces thoroughly after handling
  • Culinary Uses Beyond the Heat

Each chilli has its own flavour spectrum—from smoky to fruity, citrusy to earthy. Use chillies:

  • Pickled – Preserved jalapeños or banana peppers
  • Dried – For powders and flakes (great for rubs!)
  • In sauces or salsas – Fresh or fermented
  • Infused in oils or vinegars – Excellent for dressings or drizzles
  • Frozen or canned – Preserve a glut of harvest
