Start with the wet ingredients (instead of the rice base: vegetable pâté, avocado, salad, or marinated grated carrots) and place a line of this ingredient along the sheet.
3. Then, place the other ingredients you wish to include, always in a line along your sheet.
4. Get ready to roll! Use your fingers to moisten the edge of the sheet farthest from you with pure water. This will help seal the roll once you have finished rolling it.
The first roll is the most delicate moment of the process. Lift the sushi mat with the nori sheet and the first rows of ingredients, and roll the whole thing over the last rows of ingredients. while keeping the whole set tight to complete the first round.
5. At that moment, Release the mat, pull it forward while rolling the end of the nori sheet.. When you lift the carpet, make sure that the sheet is tightly secured underneath, so that you can finish rolling it up.
6. Let the roll rest for at least 5 to 10 minutes. before cutting it with a very sharp knife. This will soften the nori sheet a bit and make it easier and cleaner to cut.
