The new Mother Hubbard's in Baildon apparently uses vegetable oil @BarbaraofSeville horror of horrors, so I shall be giving that a miss.
I will be in murgatroyds next week, but I can't do a portion now because I'm old. In my twenties I would have done fish, chips, scraps, mushy peas and bread and butter. By my early thirties the peas and scraps had gone, by the start of my forties the bread had long disappeared and now at nearly 50 I'm down to half the fish, half chips and a spoon of curry sauce. Although if I'm in the whaler, I do love their haddock served with salad. Bizarrely it works.
I feel for you OP I have a couple of female relatives who regularly try to food shame me because they are thin and I'm fat, despite consistently eating more than me. One can't have a cup of tea without a sweet treat on the side. They do not see the irony.
Speaking of regional differences people are always surprised when they get a fishcake up here and it is fish between two scallops and covered on batter. I've also never had mint sauce on my mushy peas anywhere else, although that seems to be really dying out.
As to the people saying you must be fat to have that portion, what a load of bollocks talking body fascists. The three people I know that always order a special when having fish and chips are all thin as rakes, whilst I'm as fat as a house and have a tiny appetite (partly medical reasons). Only last week at work someone was saying that I should be really skinny because I don't eat much at all, but not all bodies are the same. I averaged just under 1300 calories a day last week, did two long walks, ran three times and gained two pounds. Plus I have a very active job, lots of lifting and on my feet about 90 per cent of the time. Before anyone asks, yes my thyroxin levels are low but the NHS say not to the point of being treatable. It's just one of those things. I like to think of myself as famine resistant.
I think basically don't comment on other people's food intake unless you want to come across as a total arse, it's horribly judgemental and unkind.
Ah I've just realised , only Yorkshire folk are going to know what a special is aren't they 😂
