Add the red onion, scallions, garlic, and jalapeno to the bowl of a food processor. Pulse until everything is evenly chopped.

Add the canned tomatoes, spices, and cilantro on top. Pour in the fresh lime juice.

Pulse a few times, checking the texture. Stop when you reach your preferred consistency. For chunkier salsa, do this step by hand.

Transfer the salsa to a bowl. Taste and adjust lime and sea salt until just right.

For a thinner salsa, stir in reserved tomato juices. Add more smoked paprika for a deeper flavor.
