This thread gave me a headache and I still don't know what to say other than 'It depends'
A little story perhaps?
Once my missus bought a big ready made paella from Waitrose for a treat one evening on the way home from work, she popped in to get some milk and saw it was reduced. As you know I don't like seafood, it was a chicken and chorizo paella. Anyway we popped it in the oven, plated up and we all started eating it.
The kids and the missus were all loving it, but from the first forkfull I was thinking 'mmm, this doesn't taste nice'. I was a little concerned that the chicken was 'off' seeing at it was reduced and on it's 'sell by' date. I said to the missus 'are you sure this hasn't got fish it?' ... she says 'no' and shows me the label on the front film wrap (no mention of anything fishy) ... 'what are you on about it doesn't taste of fish!' .. by this time, while I had been forking it around my plate in disgust her and the kids had all finished and really enjoyed it. To me it tasted pretty rank, so I dug the wrap out of the bin and looked at the rear of the label and right down the bottom of the ingredients was (I forget the exact words) something like 'fish oils or fish extract' ... or something along those lines.
Nobody else could even taste it, it was probably a tiny amount in there just to add some saltiness and enhance the flavours, but to me it was very present and ruined the whole thing.
Point being, I'm not a 'super taster' ... unless it's fish.
