Shrimp Ceviche with Ketchup

Bring water and 1 dash salt to a boil in a saucepan. Stir in shrimp. Cook for 1 minute and turn off the burner. Stir until shrimp are light red and slightly curved. Transfer cooked shrimp to a bowl using a slotted spoon. Reserve the cooking water.

Combine 1/2 cup salt, red onion, and the juice of 2 limes in a bowl. Stir and let stand for 30 minutes. Rinse onions and transfer them to a large serving bowl. Add oil.

Add shrimp, remaining lime juice, orange juice, ketchup, parsley, cilantro, and dill to the bowl with the onions. Add up to 1/2 cup of the reserved shrimp cooking water, if necessary, to thin the sauce. Refrigerate at least 1 hour or until ready to serve.
