my mother told me during the war she wrapped margarine in butter paper for my father - he never noticed until aunt who was living with them tasted it and went jesus that's margarine. dad went mad. LOL
My daughters bf is a terrible fussy eater. Drives her mad as she'lol eat anything. She'll do a lovely meals and he will take one taste and refuse to eat it. He doesn't like mash, onions, most veg, sausages,the list is endless. if he had his way he would live on pizza, chips and McDonalds.
We're rapidly approaching the point where the question will be "which takeaway will you/your partner not eat? a lot of families depend on them already for main meals and sadly it's the kids who are the experts.....
A few people have mentioned WWII and the scarcity of food - I always remember the film "The Cruel Sea" which had a couple of meal scenes with small meals on small plates and tiny forkfuls - we should eat like Jack Hawkins and his mate instead of Greg Wallace and his mate....
Because I am fussy I have made sure that my children aren't - they'll eat nearly everything. If I make them anything 'new' I make sure there's enough other stuff with it to fill them up if they don't like it (they give 'new' stuff a mark out of ten, if it's less than an average of 9 I don't make it again). I never make them eat something they genuinely don't like (they're my children, not my prisoners). They all get to make meal suggestions when I do the shopping so they aren't getting meals forced on them.
