If you like a little heat, nothing beats a well-made Serrano hot sauce that you can prepare at the comfort of your home. Preparing hot sauce at home gives you total control over the quality of ingredients, and you can increase the heat or decrease it based on your preferences.

You can also make sure that you’re not adding any chemicals or additives that can affect the taste of the sauce. Keep on reading to learn how to prepare the best Serrano hot sauce recipe.

What are Serrano Peppers?

Serrano peppers are native to Mexico and are typically hotter than jalapeño peppers. They also have a stronger and more intense flavour, even when they’re eaten raw or pickled. Because the peppers feel a little fleshy, as compared to other types of pepper, so they can be used to prepare multiple recipes like salsa. You can easily grow Serrano peppers in your backyard.

The peppers look thinner and curvier than the jalapeño peppers and have a fresh, bright kick with a medium-hot spiciness. Serrano peppers are always used for garnish or to prepare hot salsas and sauces. They’re also used in Thai dishes because they’re versatile.

The green Serrano hot sauce recipe is prepared using the green peppers, while the red Serrano hot sauce recipe is prepared using the red ones. The peppers can be yellow, green, orange, or red as they change colour when they ripen. The green peppers are usually milder than the red ripe ones.

When you first bite a Serrano pepper, you won’t immediately feel the hotness. It takes a few moments before the spiciness kicks in. Once it does, you will realise that the peppers are about 5 times hotter than jalapeño peppers, so they’re not for the faint of heart. They also have an earthy or grassy flavour to them.

How Hot are Serrano Peppers?

The Scoville scale is used to measure how hot the peppers are. According to this scale, Serrano peppers have a rating between 20,000 and 30,000 SHU, or Scoville Heat Units.

A smaller pepper will be hotter than a big one. Green peppers are not as hot as the red ones and can be used if you’re looking for a spicy addition to your dish without having something that is too overpowering or too strong.

Serrano peppers can be easily found in the supermarket. You can touch the peppers and make sure that they’re firm and free of any spots or spores.

In the summer, you will be able to get the best Serrano peppers, and you should pick them based on your preference. If you don’t like your food to be extra spicy, go for the green peppers.

Fermented Serrano Hot sauce Recipe

Get an airlock to allow the gases to escape from the jar of the fermented peppers without letting any oxygen in, as it will ruin the fermentation process. Use a fermentation weight to make sure that the peppers are properly fermented.

Once you’ve got fermented Serrano peppers, you can follow the exact same steps to prepare the Serrano hot sauce. This fermented version will have an extra flavour because of the fermented peppers.
