Wash 1 ½ pounds of ripe tomatoes under cool running water, then dice them into small, even cubes and place in a strainer. Sprinkle with kosher salt and let drain for 20-30 minutes to avoid wateriness.

While tomatoes drain, finely dice ½ a white onion and 1-2 serrano or jalapeño chiles. Finely chop ½ cup of fresh cilantro.

In a large mixing bowl, combine drained tomatoes with chopped onion, chiles, and cilantro. Squeeze in lime juice and season with additional salt to taste. Gently mix all ingredients.

Cover the bowl and let sit for at least 30 minutes to meld flavors. Refrigerate if preparing ahead of time.

Before serving, taste and adjust seasoning with salt or lime juice if needed. Serve fresh with tortilla chips or as a taco topping.
