Creating Baked Sushi Cups is simple if you follow these steps:

1. Prepare the Sushi Rice: Rinse the sushi rice thoroughly until the water runs clear. In a pot, combine the rinsed rice and water, and bring to a boil. Once boiling, reduce the heat, cover, and simmer for about 15 minutes, or until rice is tender.

2. Season the Rice: In a small bowl, mix the rice vinegar, sugar, and salt until dissolved. Once the rice is cooked, transfer it to a large bowl and gently fold in the vinegar mixture. Let it cool.

3. Prepare the Cup Mold: Preheat your oven to 375°F (190°C). Lightly grease a muffin tin with cooking spray or oil.

4. Form the Cups: In a muffin tin, take a small amount of cooled sushi rice and press it into the bottom and sides of each muffin cup to form a “cup” shape.

5. Add the Filling: In each rice cup, add a small portion of imitation crab, avocado slices, and diced cucumber. You can add a dollop of mayonnaise mixed with soy sauce and sesame oil for extra flavor.

6. Bake: Place the muffin tin in the preheated oven and bake for 15-20 minutes, or until the rice edges are slightly golden.

7. Cool and Garnish: Remove the muffin tin from the oven and let it cool for about 5 minutes. Carefully remove the sushi cups from the molds. Garnish with nori strips, sesame seeds, and chopped green onions.

8. Serve: Arrange the Baked Sushi Cups on a platter and serve immediately for the best taste.

These steps will guide you in creating these amazing cups that offer all the flavor of sushi in a fun and delightful format.
