How to Make a volcano sushi roll

An anonymous sushi chef explains how to make a Volcano Roll. First, he pats down a thin layer of rice over the sliced seaweed. Then, he spreads toasted sesame seeds all over the rice. A layer of salmon is then applied. He then spreads salmon eggs and scallions all over the salmon. Some tempura flakes go over the layer of salmon fish as well. He rolls the entire thing up very tightly to make sure it does not fall apart when eaten. He then deep-fries the entire roll and slices it into even pieces. This technique seems a bit difficult for an amateur to attempt, but this would sure make a delicious roll!
