Rinse shrimp and chop into large chunks. Toss shrimp with a little salt, chipotle chili pepper, and fresh lime juice.: As you rinse the shrimp , notice the faint briny aroma that means they are fresh; pat them completely dry so they absorb seasoning rather than steaming in their own moisture. Chopping into large chunks preserves a meaty bite and ensures you can taste the seasoned shrimp among the other textures. If the shrimp are too wet they will dilute the seasoning and make the topping soggy, so always dry them well.
Combine drained beans, corn, red onion, cilantro, lime juice and salt to taste.: When you toss the shrimp with kosher salt , chipotle chili powder, and fresh lime juice , the scent should shift to smoky and citrusy; the salt draws out flavor while the acid from the lime brightens. Use a light hand with chipotle at first, as heat levels can vary. A common mistake is over seasoning early, which can overpower the salad, so start small and taste one piece if possible.
In a large glass trifle dish or clear bowl, layer salad ingredients starting with the lettuce, black bean mixture, cucumber, tomatoes, avocado, cheese and shrimp on top.: As you fold together the rinsed black beans , grilled corn , chopped red onion , chopped cilantro , and the juice from half a lime , the mixture should smell fresh and herbaceous with a gentle tang. The beans should be moist but not watery, and the corn should add little pops of sweetness. Overmixing can bruise delicate ingredients, especially the cilantro, so gently toss to keep textures intact. If you add too much salt here it will be hard to balance later, so season gradually.
Serve with your favorite dressing such as Avocado Buttermilk Dressing on the side.: As you layer, the visual contrast is part of the appeal, so press each layer gently into the dish for neat slices when serving. The shredded romaine lettuce should be crisp and cool, the black bean mixture should sit evenly, and the diced cucumber and tomatoes should look bright and hydrated. Place creamy avocado near the top to avoid it turning brown underneath other wet ingredients. A frequent misstep is tossing everything together too early, which causes the lettuce to wilt; layering preserves crunch until you are ready to serve.
Serve with your favorite dressing such as Avocado Buttermilk Dressing on the side: Offering dressing on the side keeps the layers crisp and allows guests to control richness; a spoonful of a creamy dressing should create a silky mouthfeel against the crisp lettuce and smoky shrimp . Listen for the slight clink when scooping from a chilled dressing jar, and smell the dressing; it should complement, not compete. Avoid pouring dressing directly over the assembled salad too far in advance, as it will soften the greens and blur the distinct textures that make this dish special.
