Pat the shrimp dry with paper towels to remove excess moisture, then chop into small, bite-sized pieces.
Place the chopped shrimp in a mixing bowl and pour freshly squeezed lime juice over them, ensuring they are fully submerged.
Finely dice the red onion and jalapeño, then add them to the bowl with the shrimp. Mix gently to combine.
Chop the cilantro and optional cherry tomatoes, then fold them into the ceviche mixture for freshness and color.
Season with salt and pepper to taste, and add a pinch of smoked paprika if using, then stir to distribute evenly.
Cover the bowl with plastic wrap and refrigerate for at least 15 minutes to allow flavors to meld and the shrimp to firm up.
Once marinated, give it a gentle stir and taste for seasoning—adjust salt or lime juice if needed.
Scoop the ceviche onto plates or bowls, garnishing with additional cilantro if desired. Serve chilled for a refreshing bite.
