Spicy tuna & mango roll
An inside-out roll (uramaki): the rice is on the outside, so the nori goes on the mat rough side up, gets covered edge to edge with rice, then is flipped over before the filling goes on. Just One Cookbook's spicy tuna roll with a strip of mango added for sweetness. Start with sushi rice at room temperature.

Should look like this

Roll over the filling and tuck the edge in tight. 8Lift and tuck
20 s- Hold the filling in place with your fingers.
- Lift the near edge of the mat with your thumbs and roll the nori quickly and tightly over the filling.
- Tuck the edge in, then pull the far end of the mat towards you to keep gentle pressure.

Should look like this 
Lift the mat edge out of the way and keep rolling forwards. 9Roll forwards
20 sLift the edge of the mat (and plastic) out of the way and keep rolling forwards into a tight cylinder, with steady, gentle pressure.

Should look like this 
Mat over the roll: squeeze gently along its length. 10Squeeze to set

~2 min- Wipe a very sharp knife with a damp cloth.
- Cut the roll in half, each half in half, then each piece in half again — 8 pieces.
- Wipe the blade every cut or two. Cutting through the plastic wrap keeps the rice off your fingers.
