It took me a long time to warm to tuna. I only started eating it when I discovered sushi and I found it irresistable, certainly a totally different taste sensation to the brown sludge that they sold in cans. But it was still many years before I tried grilled tuna steaks, after all when they were cooked they were the same colour so I reasoned that they must surely taste like "hot brown sludge". Well of course I was completely wrong and I soon became hooked. Life was good ! - when fresh tuna was being landed, Salome, our local fishmongeress (sounds more sophisticated than fishwife) would phone and tip us off and it was straight onto the grill, full of colour and flavour, in fact it made better sushi than our favourite "all you eat sushi for only R 75, Wednesdays and Fridays 7 to 9 . Conditions apply" Japanese restaurant. But now I've been side swiped by a double whammy.
Firstly, in the constant battle to dupe the customer, fishmongers (not Salome of course) have learnt from their buddies the butchers that it's the bright red colour in meat that attracts us and so if that's what the customer wants then thats what the customer should get. Butchers achieve it by adding nitrites to the meat which retard that dull red colour in beef which would truly indicate quality and age and they have managed to con us that bright red = quality and freshness. Dealers in tuna, constantly battling to get their fish to the market in a pristine bright red condition, have discovered that a spray of carbon dioxide works whether the fish is frozen and subsequently defrosted or fresh, and only starts to fade to a pink colour after a few days. Now they're only doing this in the States at the moment but don't forget that's how McDonalds started.
My second knock back was reading about the mercury content in fresh tuna. I'm advised to avoid fresh bluefin tuna, the type they use for sushi and to restrict my consumption of tuna steaks to 1 meal per month. They've placed tuna in the same category as shark which I have always avoided, swordfish ditto and orange roughy which I wouldn't know if it came up and slapped me round the gills. In fact we've almost gone full circle because now it appears that the brown sludge has the lowest mercury levels of all fish and I should be wolfing it down. Life is not fair.
