Step 1: Prepare the Shrimp

Start with fresh, high-quality shrimp. Remove shells and veins, then chop into bite-sized pieces (approximately ½-inch). For food safety, ensure your shrimp is properly cleaned and kept cold until ready to use.

Step 2: Citrus Marination

In a glass or non-reactive bowl, combine the lime juice, lemon juice, and orange juice. Add the prepared shrimp, ensuring all pieces are fully submerged in the citrus mixture. Cover with plastic wrap and refrigerate for 15-20 minutes, or until the shrimp turns opaque and firm, indicating it has been “cooked” by the acid.

Step 3: Prepare the Vegetables

While the shrimp marinates, dice the red onion, cucumber, tomatoes, and jalapeños. For a milder flavor, soak the diced red onion in cold water for 5 minutes, then drain thoroughly. This removes some of the sharpness while maintaining the flavor.

Step 4: Combine All Ingredients

Once the shrimp has marinated, add the diced vegetables, chopped cilantro, olive oil, salt, and pepper to the bowl. Gently fold everything together, ensuring even distribution of flavors and ingredients. The vibrant colors should create an appealing visual mix.

Step 5: Final Touches

Just before serving, gently fold in the diced avocado. Taste and adjust seasoning if needed—perhaps a squeeze more lime juice or a pinch of salt. Let the mixture rest for 5 additional minutes to allow the flavors to meld together.
