Sushi burrito

Step 1

Put the rice in a bowl, cover with cold water and massage to remove the starch. Drain and repeat until the water runs clear. Put the rice in a small saucepan, cover with 2.5cm of water and put on a tight-fitting lid. Simmer on a medium heat for 10 mins, then take off the heat (leaving the lid on) and steam for a further 15 mins. Stir in the vinegar, then cool completely.

Step 2

Toss the cucumber and carrot matchsticks in the soy and leave to marinate.

Step 3

Lay out a sushi mat and put a nori sheet, shiny-side down, on top of it. Spread a quarter of the rice over the nori, leaving a 1cm border at the top. Mix the wasabi, ginger and lime juice.

Step 4

Layer with the avocado, cucumber and carrot, and tuna. Top with the wasabi mix and coriander. Dampen the top border with a little water, fold in both sides of the nori sheet, then use the sushi mat to help roll. Wrap in foil, slice in half and serve.
