Capsicum annuum – The Botanical Classification

The Cayenne plant is a Capsicum annuum species and belongs to the nightshade family. Annuum technically means annual in botany – but you probably know this: with proper care and good overwintering, Cayenne plants easily live longer than twelve months. After years with projects like Pika Pika and Chili Mafia, and shops like chili-saucen.com and chili-plants.com, we've learned that overwintering is almost always worthwhile.

Capsicum annuum includes hundreds of chili varieties – from mild bell peppers to hot jalapeños and the fiery cayenne. What they all have in common: they like sun, warmth, and well-drained soil. The Cayenne is particularly productive and easy to care for.

Origin and History

The origin and name of this chili variety come from the city of Cayenne in French Guiana, South America. In 1498, Christopher Columbus discovered the coast of Guiana. Cayenne city was later founded by French settlers. It is more than probable that this spice was exported from the port city of Cayenne to Europe and thus bears this name.

Because of its shape and origin, Cayenne is also known as Cow-horn, Guinea Chili, or "Spanish Pepper." Its slightly smoky and bitter taste makes it excellent for chili sauces. And because the walls are so thin-fleshed, they dry exceptionally well – a real advantage in the kitchen.

Heat Level and Scoville Scale

Wondering how hot Cayenne really is? With 30,000 to 50,000 Scoville Heat Units, it falls into the medium to high range. On a heat scale, it's often marked with a heat level of 8. For everyday use, this means a good kick, but still easily dosable. That's exactly what many chili lovers appreciate about this variety.

For comparison: Jalapeños are in the 2,500-8,000 SHU range, while Habaneros already reach 100,000-350,000 SHU. Cayenne sits right in the golden middle – hot enough for real chili flavor, but not so extreme that it makes everyday cooking impossible.

Processing and Use

Cayenne Chili Powder

Chili de Cayenne is excellent for drying and grinding into powder. Halve the pods and dry them in the oven or a dehydrator. With the oven slightly ajar, it takes about 6 to 8 hours at around 70 °C. Afterwards, simply grind them in a universal grinder or with a mortar and pestle.

You can determine the heat level yourself before drying – remove the chili seeds and scrape out the placenta wall with a knife. Most of the capsaicin is located there. To prevent the finished spice powder from clumping, simply add a few grains of rice when storing. Simple trick, big effect.

Pickling in Vinegar

Remove the stems from the fresh cayenne pods, make several lateral cuts into the pods. Bring salt water with vinegar to a boil, add chilies or bell peppers, and simmer for about an hour. Pour the hot liquid into canning jars for preservation.

Cayenne pepper and homemade hot sauces pair perfectly with Mexican and Asian dishes. In partially fiery hot Chinese cuisine, pickling in vinegar is also very popular. By the way: Fresh cayenne pods are packed with good ingredients – vitamins A, B6, E, C, as well as riboflavin, potassium, iron, copper, and manganese. That makes spiciness taste twice as good.

Growing the Chili Plant

Seeds for this famous chili variety can be found in most online chili shops, and in spring also in hardware stores or discounters. Ten cayenne seeds cost about two euros – and under normal conditions, eight out of ten germinate. Good yield.

Before planting chili seeds, it's worth soaking them in lukewarm water. Chamomile tea or diluted lemon juice also work well. A germination temperature of 22 to 28 °C is ideal. The germination period is 6 to 20 days – our cayenne chili seeds germinated on the 12th day in the mini greenhouse.

Start growing early in the year. If there's enough space in the apartment, it's advisable to start in January or February. After a short acclimatization period, the small cayenne plants can be moved outdoors in mid-May.

Coconut coir pellets are very suitable as a substrate in the propagator. For flower boxes, it's best to use potting soil – it should be well-drained, as chili plants quickly die from waterlogging. Indoors and outdoors, a sunny location is a must. The Cayenne chili needs at least eight hours of sunlight daily.

Recipe: Make Your Own Cayenne Chili Oil

Dried cayenne pods are perfect for making your own chili oil. The oil is versatile – for pizza, pasta, roasted vegetables, or marinades. A classic that every Pikantista should have in their kitchen.

Ingredients

• 8–10 dried cayenne pods
• 500 ml high-quality olive oil (or sunflower oil)
• 3–4 cloves of garlic (optional)
• 1 tsp mustard seeds (optional)
• 1 clean glass bottle with a seal

Preparation

Step 1 – Prepare the pods: Roughly break or halve the dried cayenne pods. If you prefer it milder, remove the seeds beforehand. For maximum heat, leave the seeds in.

Step 2 – Layer: Place the broken pods into the clean glass bottle, creating a layer of about 5 cm. If using garlic and mustard seeds, add them now.

Step 3 – Pour in oil: Slowly pour the oil into the bottle until all the pods are completely covered. Seal the bottle tightly.

Step 4 – Infuse: Store in a dark, cool place. Shake the bottle vigorously every two days. After about three weeks, the chili oil is ready – the heat and aroma will have fully transferred to the oil.

Use and Storage

The finished cayenne chili oil, stored in a dark and cool place, will keep for several months. The heat is retained and even intensifies over time. Just drizzle a few drops over your dish – you don't need much more. If you like it even more aromatic, you can also add dried rosemary sprigs or thyme to the oil.
