Wash the ripe tomatoes under cold water, chop them, and place them in a fine strainer for 5 minutes to drain excess liquid.

Transfer the drained tomatoes to a blender, add diced onion, chopped cilantro, lime juice, jalapeño, garlic powder, cumin, salt, and black pepper.

Blend the mixture for 15-30 seconds to reach your desired consistency.

Pour the blended salsa into a clean jar, taste, and adjust seasoning if needed. Store it in the refrigerator.
