Cook for 5 minutes and add 16oz short grain rice.
Cook another 5 mins stirring until rice is slightly toasted.l
Stir every 5 minutes for a total cooking time of 18 minutes. (If water evaporates too quickly you can add more if needed)

Mix nori into rice and divide mixture into 1 1/2-ounce portions. Roll each into a ball.
In a deep-fryer or tall-sided pot, heat canola oil to 350 degrees.
In a small bowl, whisk together eggs and milk and season with salt and pepper.
Roll each ball in flour, dip into egg and milk mixture, and roll in breadcrumbs.
Fry balls in oil until golden brown, working in batches. Remove with spider or slotted spoon and drain on paper towels. Season with salt and pepper to taste.
Cut balls in half and fill with tuna tartar mixture. Close ball and add 8 pieces of fried pasta to resemble the legs of a spider. Add two scallion rings for the eyes and one scallion ring for the mouth. Secure with a littler bit of mayonnaise. Use fermented tea leaves for eye brows.
