Sriracha is one of the most recognizable hot sauces in the world. It’s garlicky, slightly sweet, and known for its bright red colour. The traditional version uses red jalapeños, which provide balanced heat and the classic flavour most people expect from Sriracha.
In Canada, however, finding mature red jalapeños can be difficult. Most jalapeños are harvested and sold while they are still green. Making finding Red ones extremely difficult.
The Fresno is a Substitute for the Hard to Find Red Jalapeño
Because of that, Fresno peppers make one of the best substitutes for homemade Sriracha. They have a similar heat level and a vibrant red colour that looks right in the finished sauce. Fresno peppers also bring a slightly fruitier flavour that works well in chili garlic sauces.
There is one small difference to keep in mind. Fresno peppers often have thinner but tougher skins than jalapeños.When the peppers are not fully mature, those skins can be stubborn and harder for a blender to break down completely.
A little extra prep can help. Slice the peppers open and check the inside walls. If the flesh feels firm, run a paring knife along the inside of the pepper to remove some of the tougher ribs. This step makes blending much easier and helps produce a smoother sauce.
Texture can be Adjusted in a few ways
Once blended and simmered, you can choose the texture you prefer. Some cooks enjoy a rustic sauce with visible chili pieces. Others want the smooth texture found in bottled Sriracha.
To achieve that smoother style, strain the sauce through a fine mesh sieve. This removes seeds and skins, leaving behind a silky chilli garlic sauce.
Unstrained Sriracha
Strained Sriracha
Straining will thin the sauce slightly. If you want a thicker consistency, blend in a small pinch of xanthan gum. It thickens the sauce while keeping it smooth and pourable.

Let us know how it was!Frequently Asked Questions
Can I use green jalapeños instead of red peppers?
Yes, but the flavour and colour will change. Green jalapeños produce a hotter, more vegetal sauce and the colour will be green instead of the classic bright red Sriracha colour.
Why are red jalapeños hard to find in Canada?
Most jalapeños are harvested and sold while they are still green. Farmers often pick them earlier because they store and ship better. Red jalapeños are simply fully ripened jalapeños, which means they appear less frequently in Canadian grocery stores.
Why are Fresno peppers a good substitute for red jalapeños?
Fresno peppers have a similar heat level and a bright red colour that works well in chili sauces. They also bring a slightly fruitier flavour that pairs nicely with garlic and vinegar in homemade Sriracha.
Why should I strain homemade Sriracha?
Straining removes pepper skins and seeds. This creates a smoother sauce that looks and pours more like the bottled Sriracha you find in stores.
How can I make homemade Sriracha thicker?
After straining the sauce, you can blend in a very small amount of xanthan gum. This thickens the sauce while keeping it smooth and pourable.
How spicy is homemade Sriracha?
The heat depends on the peppers you use. Red jalapeños and Fresno peppers usually fall in the 2,500–10,000 Scoville Heat Unit range, which produces a medium heat sauce similar to traditional Sriracha.
How long does homemade Sriracha last?
Stored in a sealed bottle in the refrigerator, homemade Sriracha typically lasts 3 to 4 weeks.
Do I need to ferment Sriracha?
No. Fermentation adds complexity and tang, but a fresh blended and simmered version still produces a delicious chili garlic sauce.
