Rinse the sushi rice under cold water until the water runs clear. Cook according to the package instructions. Once cooked, mix with rice vinegar and a pinch of salt. Let cool.

Prepare Sashimi

Slice maguro and salmon into thin sashimi pieces and arrange on a plate. Serve with soy sauce and wasabi on the side.

Prepare Spicy Salmon Roll

On a bamboo mat, place a sheet of nori. Spread a thin layer of sushi rice over the nori, leaving a 1-inch border at the top. Place sliced cucumber, avocado, and spicy salmon mix (diced salmon mixed with spicy mayo) along the bottom edge. Roll tightly and slice into pieces.

Prepare Tempura

Mix tempura batter according to package instructions. Heat oil in a deep pan. Dip prawns and mixed vegetables in the batter and fry until golden brown. Drain on paper towels and season with salt.
