Even if the only sushi fillings you have in your fridge are cream cheese (home made Boursin) and smoked salmon, you can turn your boring old Philadelphia roll into a dramatic visual by colouring your sushi rice and then using it to make an inside out roll.
The ingredient responsible for that change … red cabbage. Grate a fist sized wedge finely on your microplane zester, drain off the liquid, add a bit of lemon juice to the liquid to make the colour ‘pop’ and stir it into your cooked sushi rice. Easy peasy. (NOTE: My method involved adding 2 tbsp of seasoned rice vinegar to a generous handful of finely shredded red cabbage, pureeing it and then straining the resulting liquid into a cup or two of hot, freshly cooked sushi rice.)
