Tonight, it's homemade sushi! But instead of tuna and salmon, give sardine maki a try. Cook the rice (preferably sushi rice) and let cool. Add some vinegar, and stir well. Place a sheet of sushi Nori seaweed on a bamboo mat, spread the rice over it, leaving a 2-cm border on all sides. Add thinly sliced carrot or cucumber sticks and roughly chopped and de-boned sardines. Roll up your maki, and let sit in the fridge for 1 hour. Cut into sushi-style segments, and serve with spicy dipping sauce.
