"bits" when I was a kid growing up in 1970s Nottinghamshire, IIRC. But as my local chipshop proprietors were distinctly right wing, bits were only available to regular customers buying something else, not a cheap option for the poor.
THe reason I need to know is that some people were having lunch with a friend of mine in Tel Aviv and they were talking about FIsh and Chips, and these scraps or scrobblings or bits or whatever were mentioned by someone who'd grown up in SHeffield but he couldnt remember what they were called, so this friend said "Oh Jackie's bound to know" (alas, not true) and he emailed ME...so I fell upon the mercy of the clever Forum people...and hey presto!
Jackie, I mant to say ' salt and vinegar crisps'! the cholesterol bit? Fish and chips, pie and mash were the only ' fast food' places available, so our intake of fats i suppose were limited as prepacked food was not even heard of!
on the very rare occasions we had a joint of meat we would scrape the jelly off the dripping onto our toast, then the dripping would be boiled with water, then the water thrown away and mum would make a pie with the 'clean' fat, apple or meat pie the pastry was always dripping!
