Creating Spicy Shrimp Sushi Stacks can be straightforward if you follow these simple steps:

1. Rinse the Sushi Rice: Wash the sushi rice under cold water until the water runs clear to remove excess starch.
2. Cook the Rice: In a medium pot, combine the rinsed rice and water. Bring to a boil over high heat. Once boiling, reduce heat to low, cover, and simmer for 18-20 minutes or until rice is tender. Remove from heat and let sit, covered, for 10 minutes.
3. Prepare the Shrimp: While the rice cooks, heat a skillet over medium heat. Add shrimp and sauté until pink and cooked through, about 3-5 minutes. Season with soy sauce and sesame oil. Stir to combine and remove from heat.
4. Make the Spicy Sauce: In a small bowl, mix mayonnaise and sriracha until smooth. Taste and adjust spice level if necessary.
5. Prepare Vegetables: Slice avocado and dice cucumber while the shrimp are cooking.
6. Assemble the Stacks: In a serving ring or a small bowl, layer the cooked sushi rice at the bottom, followed by a layer of shrimp, then the spicy mayo, a layer of diced cucumbers, and sliced avocado.
7. Finish with Nori and Scallions: Top the stacks with nori strips and garnish with sesame seeds and green onions.
8. Carefully Remove the Ring: Gently remove the ring or bowl after stacking to reveal the beautifully layered sushi stack.
9. Repeat: Repeat this process for the remaining ingredients to create more stacks.
10. Final Touch: Drizzle with soy sauce for added flavor before serving.
