Seared tuna steak | Jamie Oliver fish & seafood recipe

“When buying tuna you should look for meat that is evenly coloured, dark red and has a fine, tight grain free of large sinews. Generally you get better tuna in good fishmongers than in supermarkets, but sometimes the supermarkets get a good batch in, so keep your eyes peeled. There is a bit of a thing about it being fashionable to serve tuna pink; if you buy good-quality fresh tuna the last thing you want to do is cook it all the way through and make it taste like tinned tuna, so yes, good-quality fresh tuna should be served rare or very pink. ”
