Method
1
Cut the white-bread slices into quarters (8 triangular pieces per slice) to form 32 crostini rounds. Toss with 2 tbsp olive-oil and spread on a baking sheet without overlapping.
2
Peel the sweet-potato and cut into 5mm dice. You need about 1 cup diced sweet-potato.

4
Place the baking sheet in an oven preheated to 190C (375F). Toast the bread pieces for 8 minutes, then remove and dust each piece with almond-flour, pressing gently so the flour adheres. Return to the oven for 5-6 minutes until the almond flour is toasted and the bread is deeply golden. Set aside to cool.
5
While the crostini toasts, toss the diced sweet-potato with 1 tbsp olive-oil and 0.25 tsp salt. Spread on a second baking sheet and roast alongside the crostini for 12-14 minutes, until tender and caramelized at the edges. Remove and let cool slightly.
6
Toss the shrimp with 0.75 tsp salt, cayenne, and 1 tbsp lime juice. Let rest 2 minutes to bloom the seasoning.
7
Heat 2 tbsp olive-oil in a large skillet over high heat until it shimmers and just begins to smoke lightly. Add the shrimp in a single layer — do not crowd the pan. Sear for 90 seconds per side until pink, firm, and lightly charred at the edges. Transfer to a plate. Pour the remaining lime juice from the bowl over the hot shrimp immediately.
8
In the same skillet over medium-high heat, cook the corn kernels with 0.25 tsp salt for 3-4 minutes until charred and bright. Add the minced garlic and cook 30 seconds until fragrant. Transfer to a bowl.
9
Gently fold the roasted sweet-potato into the corn bowl. Add the diced yellow-onion, 2 tbsp lime juice, and 1 tbsp olive-oil. Toss to combine. Taste and adjust salt.
10
Arrange the almond-flour crostini on a serving platter. Spoon a portion of the sweet potato-corn mixture onto each crostino. Top with 2-3 seared shrimp per piece.
11
Drizzle the finished crostini with 1 tbsp olive-oil, squeeze over the remaining lime juice, and scatter fresh cilantro leaves across the top. Serve immediately.

Safety & Storage
Cooking Temperature
Shrimp must reach an internal temperature of 145°F (63°C) when seared. The high-heat skillet cooking (shimmering oil that lightly smokes) achieves this, but ensure shrimp is pink, firm, and opaque throughout with no translucent centers.
Cross Contamination
Raw shrimp and shellfish juices can cross-contaminate other ingredients. Use separate cutting boards and utensils for raw shrimp preparation. Avoid touching the almond-flour crostini or vegetables with hands or tools that have contacted raw shrimp.
High Risk Population
Shellfish is a high-risk allergen and food item. Pregnant women, young children, elderly individuals, and immunocompromised persons are at greater risk for seafood-related foodborne illness. Ensure shrimp is fully cooked before serving to these populations.
Storage
Keep shrimp refrigerated at 40°F (4°C) or below until ready to cook. Once assembled, the crostini with shrimp topping should be served immediately and not left at room temperature for more than 2 hours (1 hour if ambient temperature is above 90°F/32°C).
Allergen Warning
This dish contains multiple major allergens: tree nuts (almond flour), shellfish (shrimp), and gluten (white bread). Clearly label and communicate all allergens to guests before serving. Avoid any garnish or preparation changes that could introduce additional allergens.
Handling
When tossing shrimp with seasoning (salt, cayenne, lime juice), use clean utensils. The 2-minute rest allows the seasoning to bloom but does not cook the shrimp—only the subsequent high-heat sear provides the kill step.
Cilantro and lime juice are acidic and may cause contact dermatitis in sensitive individuals. Handle with care during garnishing and wash hands thoroughly after preparation.
Pro Tips
Technique
The shrimp are done when they curl into a gentle C-shape — if they curl into an O, they have gone too far. That 90-second sear per side is not a suggestion; it is the exact moment between perfect and overcooked.
Substitution
If almond flour is unavailable, toasted panko breadcrumbs pressed firmly onto the oiled bread work beautifully — you still get that golden crunch and nutty finish without changing the spirit of the dish.
From the chef
Growing up at my mother's cevichería near the fish market in Barranco, I learned that the sea gives you something extraordinary if you know exactly when to stop touching it. This crostini holds that same precise moment — shrimp seared just past raw, bright lime cutting through sweet potato's earthiness, and that cayenne warmth I always crave. It is food with good timing, and timing is everything.
