Start by placing the chilled rice into a mixing bowl. Add soy sauce, sesame oil, and cornstarch, then gently mix until everything is evenly coated. The cornstarch helps the rice hold together and develop a crisp exterior.
Divide the rice mixture into equal portions and press them firmly into small round or square patties. Compacting them well prevents them from falling apart during cooking. Place them on a tray while you prepare the skillet.
Heat oil in a non-stick skillet over medium heat. Carefully place the rice cakes into the pan and cook until the bottoms become golden and crunchy. Flip them gently and cook the other side until equally crisp.
Add the cooked edamame, tahini, lemon juice, garlic, water, and salt to a food processor. Blend until completely smooth and creamy. Add a little extra water if needed to achieve a spreadable consistency.
Brush the avocado slices lightly with lime juice. Combine the white and black sesame seeds on a plate and gently press each avocado slice into the seeds. This creates a beautiful coating and extra crunch.
Spread a generous layer of edamame whip over each crispy rice cake. Place a sesame-coated avocado slice on top and gently press it into the spread. Finish with your preferred garnishes.
Add green onions, microgreens, chili flakes, or cilantro for extra color and flavor. Serve immediately while the rice cakes are still warm and crispy. The contrast between hot and cool ingredients is what makes this recipe shine.
