Cayenne Pepper is a very popular spice in a variety of cuisines & usually found in powder form.
It is also a key ingredient in a variety of hot sauces, particularly those employing vinegar as a preservative. Dust potatoes or root veg before roasting for a spicy twist, or add a pinch to chillies, stews & stir fries.
With a Scoville scale between 30,000 – 50,000 it is hotter than jalapeños but less than chillies like the Bird’s Eye, Habanero & Scotch Bonnet. Because of its (somewhat) lesser heat, some of the fruitiness does come through, although it does still pack a punch!
