Raw shrimp bathed in a dramatic black chile and soy-lime sauce is a bold Sinaloan creation. This high protein, keto-friendly dish is a fresh, healthy option for adventurous clean eats.
Toast the dried negro chiles in a hot skillet over medium heat for 1-2 minutes until fragrant but not burned; cool, then soak them in hot water for 10 minutes.
Drain the chiles, then blend with lime juice, soy sauce, Maggi, worcestershire sauce, garlic, and salt until perfectly smooth and jet-black.
In a mixing bowl, toss the raw shrimp with half of the black chile sauce, making sure every piece is coated, and refrigerate for 20 minutes to 'cook' in lime juice.
Add the thinly sliced onion and cucumber to the shrimp; toss gently, then chill for another 10 minutes so the vegetables crisp up.
Arrange the aguachile on a platter with avocado slices and a few ice cubes around the edges to keep it cold and fresh. Drizzle with remaining sauce before serving.
