Ingredients
- 8 oz fresh white fish fillets (such as cod or sea bass)
- 1/2 cup fresh lime juice
- 1/4 cup fresh lemon juice
- 1/2 medium, finely diced red onion
- 2 tbsp, chopped fresh cilantro
- 1 small, deseeded and finely chopped jalapeño pepper
- 1/2 medium, diced cucumber
- 1 tsp sea salt
- 1/4 tsp black pepper
- 1 medium, diced avocado
Instructions
- Step 1: Cut 8 oz fresh white fish fillets into 1/2-inch cubes and place them in a non-reactive bowl. Pour 1/2 cup fresh lime juice and 1/4 cup fresh lemon juice over the fish, ensuring all pieces are submerged. Cover and refrigerate for 30 minutes until the fish turns opaque and is 'cooked' by the citrus.
- Step 2: While the fish cures, finely dice 1/2 medium red onion, chop 2 tbsp fresh cilantro, deseed and finely chop 1 small jalapeño pepper, and dice 1/2 medium cucumber.
- Step 3: After 30 minutes, drain half of the citrus juice from the fish mixture, then add the diced onion, cilantro, jalapeño, cucumber, 1 tsp sea salt, and 1/4 tsp black pepper. Gently fold to combine and refrigerate for another 10 minutes to meld flavors.
- Step 4: Just before serving, gently fold in 1 diced medium avocado to add creaminess and a cool contrast. Serve chilled for a bright, fresh appetizer.
