1- Rinse jalapenos thoroughly and remove stems; wash hands after handling peppers to avoid irritation.

2- In a pan, sauté roughly chopped 1/2 onion and peeled garlic cloves in oil over medium heat until the onion starts to brown for added sweetness.

3- Add Mexican oregano, freshly cracked black pepper, and cumin if using; cook briefly until fragrant to build deeper flavors.

4- Add jalapenos, white vinegar, water, and salt to the pan and bring to a simmer to meld the ingredients together.

5- Transfer the mixture to a blender, add cilantro sprigs and lime juice for freshness, then blend to your preferred consistency, whether chunky or smooth.

6- Pour the blended sauce into bottles or jars for easy storage, and let it cool before sealing.

7- Store the hot sauce in the refrigerator, where it will keep for at least one month to enjoy later.
