My most hated meal I had when I was a kid is not really a dish, it was an actual solitary meal. My mum wanted me & my bro to eat more vegetables. So on serving our tea one night she disguised some parsnips as potato chips. Carefully cut into chip shapes.
These didn't go down well with me & my bro & the mental trauma it produced re-wired my brain into hating parsnips for a good 30 years.
These days roasted parsnips, slightly caramelised on the edges are great, I can't get enough of them!
Also I hated just about every school dinner. Aged about 8 or 9 I would really fear dinnertime at school. The smell of the canteen turned my stomach & if I ever smell a similar smell even today I am transported back to those dark days. Anything with swede, turnips, sprouts or for dessert, pink custard were the killers for me.
We had to clear our own plates but the dinner ladies had to inspect if we had eaten enough but I had got the art of dodging these folks down to a tee so I could scoop the lot into the bin.
On the rare occasions I got caught I would be forced to sit in front of the meal until I had eaten it. All my mates were out in the playground, peering in the window to see what was going on & I would sit there on my own in the canteen with the meal in front of me like on a hunger strike and miss the playtime. Under the gaze of the strolling dinner lady, arms behind her back. That was torture!
