A flavorful and easy-to-make taco sauce that adds a spicy kick to your favorite dishes.
Combine the tomato paste and water in a saucepan over medium heat.
Stir constantly to prevent the mixture from sticking to the bottom.
Mix in the cayenne pepper, chili powder, salt, cornstarch, and vinegar.
Whisk the mixture to ensure the cornstarch dissolves completely.
Puree the onion and jalapeno in a food processor until smooth.
For a milder sauce, remove the seeds from the jalapeno before blending.
Add the pureed mixture to the saucepan and bring to a boil, stirring frequently.
Keep stirring to avoid burning and ensure even cooking.
Once boiling, cook for an additional 3 minutes, then remove from heat.
This step helps thicken the sauce and meld the flavors together.
Allow the sauce to cool before transferring it to an airtight container.
Cooling prevents condensation from forming in the container, which could dilute the sauce.
