Slice cucumbers long with a potato knife after washing them with thick salt. At this time, don't lay down the knife too much, stand it, and press it hard to do it well.

Tear crab meat into small pieces by hand.

Mix the crab meat with half a teaspoon of salt, 1 teaspoon of sugar, 4 tablespoons of mayonnaise, half a tablespoon of sesame seeds and pepper powder.

I put a tablespoon of perilla oil, half a teaspoon of salt, and a tablespoon of sesame seeds in a bowl full of rice.
You can use sweet vinegar. Sweet vinegar is the ratio of vinegar: sugar: salt=2:1:0.3.
Mix it and make small rice balls that will go into the cucumber

When the water boils, add a little bit of thick salt, blanch the chives briefly, and rinse it in cold water. If you don't have chives, slice the end of the cucumber thinly and stick it with only cucumber moisture.

I used sliced cucumbers in half. So there are about 14 cucumber rolls per cucumber. Add rice balls and roll them so that they are not loose.

I tied it tightly with blanched chives twice.

Put as much creamy salad as you can on top of this.
