Spicy Scallops Sushi Roll

Spicy Scallops Sushi Roll!
INGREDIENTS :

No need to be too precise about exact quantities here as personal tastes can (and ought to) be different!
-Sushi rice: as much as you will need
-Nori/dry seaweed: use large sheets (maximum size)
-Scallops: Only fresh, please.
-Tobikko (Flying Fish roe): as fresh as possible.
-Tempura kasu: these are the pieces of batter found in the oil after frying tenpura. The Japanese do not throw them away Scoop them out as early as possible and lay them on a piece of paper kitchen to take off excess oil. Let them cool completely. If you do use them immediately, store them by deep-freezing them inside an airtight vinyl pouch!
-Coarsely cruched peanuts. These with the tempura kasu will add a welcome crunchiness.
-Mayonnaise.
Now, if you don’t like it, make a thick dressing. The trick is to make a simple vinaigrette with a lot of soft Dijon mustrd which will give it consistency.
Mayonnaise
-Chili pepper powder.
-Cucumber: finely chopped. Cut the cucumber in 5 cm, 2-inch long pieces. Cut each piece into thin slices. Cut the slices again into very fine strips.
RECIPE:
-In a bowl drop the scallops cut into small pieces. Add the tobikko/Flyiing Fish roe, tempura kasu, crushed peanuts, mayonnaise and chili pepper. Mix well. Taste and rectify the seasoning if needed.
-Spread a large sushi roll mat out and cover it with a sheet of nori/dry seaweed.
-Spread a layer of sushi rice over the whole nori/dry seaweed as equally as possible. Careful with the quantity. Too much and you won’t be able to roll it!
-Leave a small strip space at one extremity. Line with the cucumber in a half centimeter/less than half an inch wide strip.
-Leave a space between the cucumber and scallops mixture to obtain the same pattern as shown in above picture. Spread the scallops evenly. Leave a space at the other extremity to allow for a tight closing of the roll.
-Carefully roll the sushi from the cucumber end. Once completely rolled, pressed gently and evenly so as to allow the nori/seaweed to seal the roll.
-Unroll the mat. Cut the roll and serve at once.
-There is no real need for extra soy sauce or whatever dressing, but this a personal taste.
VEGAN OPTION:
-Skip the Tobikko/Flying Fish roe. Replace with very finely chopped sweet red pimento.
-Instead of using scallops, use mushrooms. White colored and soft varieties such as button mushrooms, shimeji or even eringi are best.
Cut the mushrooms and sprinkle with lemon juice to prevent them from darkening.
Fry them in olive oil until they are soft.
Let them cool completely and drain them thoroughly..
-As for the mayonnaise, use a vegan substitute or make a dressing as suggested above
