Whether it’s on the shelf of a restaurant or your kitchen, you can see red pepper flakes everywhere.

There’s no doubt that we all have used or experienced red pepper flakes on our food, at least once.

But have you ever wondered what they are?

Questions like, where do they come from, what peppers are used, and are their seeds used, must be circulating your mind. No? Just us then.  

Despite the popularity of this ingredient across the world, there aren’t many people aware of what red pepper flakes are. However, it’s time we find out and answer all those questions. 

What are red pepper flakes?

Let’s begin by answering the main question. What are red pepper flakes?

A simple answer would be that they are a spice made up of dried and crushed chilli peppers. But this won’t be enough to answer this question; we need to go deeper into their origins.

If we trace origins of this spice, we’ll end up with the capsicum annum family, a plant species consisting of chillies and peppers, and you’re quite familiar with this species. Jalapeño, Fresno, bell peppers, and Anaheim peppers are all related to this family.

Red pepper flakes are made up of a variety of peppers from this species. However, they are usually made from cayenne peppers.

It’s worth noting that companies use different blends and ratios of different types of peppers to create unique tastes of red pepper flakes.

It’s also important to note that red pepper flakes are different from chilli flakes. Chilli flakes are made of a single type of pepper, while the contrary, as discussed earlier, is made up of several pepper types, which creates a multi-dimensional flavour. 

You must’ve noticed the difference yourself; a red pepper flakes jar has a variety of different seeds with different colour shades, but a jar of chilli flakes has a uniform texture and colour.

How are red pepper flakes made?

Having discussed what red chilli flakes are, you must be wondering how they are manufactured.

After harvesting these different peppers to be combined in a jar, they are first dried up. The drying stage can take a day to around three weeks, depending on the size and type of the peppers. Larger ones take a longer time.

The drying duration is also dependent on the method that is being used to dry them. In factories, chillies are dried rapidly using machines like dehydrators and industrial ovens, while at a smaller scale, they take longer to dry. 

After they’ve been effectively dried up, it’s time for them to be crushed and pulverized. Again, this process is quite efficient in factories, as they have pulverizing machines to do this instantly. Some people even crush these chillies by hand in some areas. Everything from the skin of the pepper to the seeds is crushed.

At the end of this stage, red pepper flakes have been created successfully, and are ready to be poured into containers, so that they can be shipped to restaurants are stores, where you can enjoy them with your food. 

Substitute for red pepper flakes

There’s no doubt that red pepper flakes are frequently used at our homes in great dishes, they’re not just used to achieve heat, unlike chilli flakes. They have their unique taste coupled with a kick of heat.

But what happens when you run out of them or forgot to pick them up from the store? Don’t worry; there is a substitute.

If there’s a jar of chilli powder or cayenne powder in your home, you won’t have any problems cooking your food without red pepper flakes. As you now know that cayenne peppers are the majority of peppers used, the cayenne powder will be a good substitute. However, you’ll still be missing the texture of seeds.

Ever since I started cooking I’ve been fascinated by how different people’s techniques are and how they best utilise the ingredients around them. Even the person living next door will have their own unique way of frying an egg or cooking a salmon fillet.

This fascination led me on a journey across the globe to discover the countless practices and traditions the world of cooking has to offer. I thought you’d enjoy and find value in sharing that journey with me so I created Cooked Best!
