I like the albacore tuna as well... I find other tuna smells and tastes like what I would think cat food would!
Even if you can pull the ring, sometimes it gets half way and you run out of leverage. OH discovered if you then push the lid down (reversing your pulling) then pull again, the leverage advantage returns and the lid actually will come off!
I do this over the sink and then use the loose lid to press down onto the tuna and 'squeeze' the water out and down the drain. Or if you are fussy, put the tuna in a fine metal mesh strainer (not a sieve which has big holes).
Lately my Sainsbury's has not had the Taste The Diff albacore in water, only olive oil (supply problem I was told). So I definitely am using the strainer now to get rid of the oil. lso, I refrigerate the tin, the oil then forms lumps and are easy to pick out, then just rinse the tuna in the strainer.
