What Are Red Pepper Flakes, Anyway?

Red pepper flakes are the dried, crushed bits of various types of red chili peppers. Think of them as nature’s fiery confetti — tiny pieces that pack a punch when sprinkled into sauces, soups, stir-fries, and even cocktails.

Commonly made from cayenne, jalapeño, or other hot peppers, these flakes offer a rustic, uneven texture and bold flavor that many home cooks and chefs swear by. Unlike chili powders, which are usually ground into a fine dust, red pepper flakes retain more visual and textural character — perfect for those who like to see the heat they're getting into.

Flavor Profile: Mild to Wild

The spiciness of red pepper flakes can vary depending on the type of pepper used and how much of the seeds and inner membranes are included. Here's a quick comparison:

Type of Pepper	Scoville Heat Units (SHU)	Flavor Notes
Cayenne	30,000 – 50,000 SHU	Earthy, bright, with sharp bite
Jalapeño	2,500 – 8,000 SHU	Grassy, slightly smoky, mild kick
Hatch	2,500 – 30,000 SHU	Variety-dependent; nutty and sweet when roasted
Bird’s Eye Chili	50,000 – 100,000 SHU	Super spicy, citrusy punch

Pro Tip: Want more control over the heat? Make your own red pepper flakes at home using milder chilies — or go full beast mode with ghost pepper versions if you dare!

How Are They Made? From Garden to Jar

1. Grow: Peppers are grown until fully mature and red.
2. Dry: Chilies are sun-dried or oven-dried until brittle.
3. Crush: Dried chilies are broken into flakes by hand or machine.
4. Pack: Stored in jars, shakers, or bulk containers for use.

Some commercial versions include salt or anti-caking agents, so read labels carefully if you’re watching sodium or prefer pure spice.

Pro Cooking Tips: Use Them Like a Chef

Red pepper flakes are incredibly versatile — here’s how to wield their power without blowing your taste buds out of the water:

• Toasted for More Flavor: Dry toast flakes in a pan before adding them to dishes for a deeper, smokier taste.
• Sprinkle Before Serving: For a fresh burst of heat and color, sprinkle at the end rather than cooking them in early.
• Olive Oil Infusion: Add flakes to olive oil to make a fiery condiment perfect for drizzling over pizza or bread.
• Balance Sweetness: Counterbalance sweetness in tomato sauces or desserts (yes, really!) with a pinch of flakes.
• Mix It Up: Combine with garlic, herbs, or citrus zest for custom seasoning blends.

Health Benefits: Spice That Loves You Back

Red pepper flakes contain capsaicin, the compound responsible for their heat — and also their health benefits:

• Metabolism Boost: Capsaicin may temporarily speed up metabolism.
• Pain Relief: Topical capsaicin creams can reduce joint and muscle pain.
• Antioxidant Powerhouse: Rich in vitamins A and C, plus antioxidants that support immunity.
• Digestive Aid: In moderation, it can stimulate digestion and ease bloating.

Caution: Too much spice can irritate sensitive stomachs, so enjoy responsibly.
