Put a Japanese bamboo rolling mat on a clean, flat surface. Place a nori sheet onto it. Remember to turn the glossy side down.
Cover the mat with plastic to stop the rice from becoming caught in the gaps between the bamboo slats.
One helpful tip to avoid the rice sticking to your fingers is to dip all the fingertips in water before making the rolls.
Spread the sushi rice evenly over the nori sheet. Ensure you leave one inch on the strip edge without rice.
Arrange the filling ingredients (fried oysters, julienned seedless cucumbers, sliced ripe avocado) along the sushi rice, about two inches above the roll's bottom.
Put your thumbs beneath the rolling mat and use other fingers to place the ingredients to secure them. Roll the mat up. Ensure it is over all the fillings. Roll tightly.
Sprinkle a little water around the nori sheet's border that isn't covered with rice. Seal the roll closed by squeezing and rolling.
Use a slicing knife to divide the roll into eight pieces. Remember to wipe the blade between cuttings.
Eat fried oyster sushi rolls with pickled ginger and wasabi. Enjoy your meal!
