Hey! I like our chalky, fruity Smarties. 
My, what small coins you have? Smarties are much smaller than even a dime.
Hidden Valley Ranch, a dude ranch in California, was the originator of “Ranch” dressing. They still make it under their own brand name. The wikipedia article doesn’t say, but I imagine that the last 10 years or so has been a crucial time for the brand, since it seems that “Ranch” dressing is on the cusp of losing its unique branding and becoming the next “aspirin”.
I (an American) used to date a Canadian guy. I live about 15 miles from the US/Canada border, so it wasn’t difficult seeing each other. He invited me over for dinner and was preparing potatoes. He asked me what kind of potatoes I’d like for dinner and we agreed that mashed would be good.
When we sat down to eat the potatoes were literally mashed potatoes. Just boiled potatoes mashed down on the plate. Here in the US, our version also contains milk or cream, butter and salt whipped together with a mixer.
When I questioned this, he said, what us Americans call mashed potatoes, Canadians call creamed potatoes which technically makes more sense.
Kraft foods’ lawyers would like to have a word with you.
KFC called them biscuits. You’d get one or two (this would be '89 - '90, so I can’t remember exactly) and a pat of butter as a side along with fries, a tub of beans and/or coleslaw with a bucket of chicken.
So why is it not called lemon juice, then?
You’ve explained it in such a way that your explanation actually detracts from your own logic for calling it what you do call it.
To me, lemon juice comes from lemons, orange juice comes from oranges and pineapple juice comes from pineapples. Lemonade is a fizzy lemon flavoured drink, orangeade is a fizzy orange flavoured drink and pineappleade is a fizzy pineapple flavoured drink.
I have learnt from this board that what we call cider, Americans call hard cider. I can’t recall what you call your other, non-alcoholic cider, but we’d call that appleade. Which fits in with the lemonade business, too.
Because we already have something over here called lemon juice and it’s not anything you drink, believe me. Lemonade is the drink and it’s from lemons mixed with water and sugar. Lemon JUICE is sort of like a condiment here. It’s usually made with alcholic drinks, but not drinkable straight (it’s very, very bitter and would probably induce your gag reflex if you drank it straight–although I don’t know, I’ve never tried. I have tried putting drops of it in my mouth, though, and it’s pretty nasty unless mixed in a drink).
Speaking of which…I seem to remember Sprite and 7up being weird over there too. Those are lemon-lime sodas, right? Here they are…but over there aren’t THEY considered/called “lemonade”?
Here they’re called soda or pop.
Orange juice and pineapple juice are all juice with no added sugar or water.
The generic term is gelatin. Jell-O is a brand name.
Pop, soft drink, fizzy drink or fizzy pop would be the main terms for carbonated drinks here. I do use soda sometimes, but that’s 'cos I was married to an American. Anyway, Sprite and 7up are close to our lemonade, but are not called it because of the addition of lime. Were they just lemon then, yeah, they’d be brands of lemonade.
If they ever had a trademark on “Ranch”, they lost it for lack of defense long ago. I can go to any supermarket in the country, and buy store-brand ranch dressing, plus ranch dressing of several non-Hidden Valley name brands. The Hidden Valley trademark is probably still strong, but nobody calls it “Hidden Valley Ranch” except in commercials.
If it’s ever not clear from the context, you can specify “sweet cider” to mean the non-alcoholic stuff. But usually, non-alcoholic cider is just “cider”.
And lemon juice is about the least bitter foodstuff you’ll ever encounter. Sour is the exact opposite of bitter. The point remains, though, that it’s not really drinkable straight, hence the added water and sugar.
My British FIL made those last night–just mased up some potatoes, with no milk or anything. Bland as hell, with no salt even. Waste of a good potato.
What you describe as jelly rather than jam does exist, less commonly, in Britain, and it’s called…jelly. Example..
You have no Cool Ranch Doritos? How Can a country with that much pot have no Cool Ranch Doritos? What a monstrously unfair Cosmic tragedy
Aren’t “digestives” graham crackers? I don’t know, do people consider them a type of cookie (or biscuit) or a type of cracker? They don’t come to mind when I think of cookies.
“Hidden Valley Ranch” is a dead trademark for salad dressings as of August 11, 2008, per the U.S. Patent and Trademark Office. Likewise, the single word “Ranch” for a dressing mix for salads is dead, as is “Ranch Dressing” for salad dressing.
I know what lemon juice is. Lemons and their juice get exported all over the place these days, you know. 
Lemon juice is the juice of a lemon. No explanation neccessary on that one. No sirree.
The point I was making is that your explanation just didn’t add up.
Saying that lemonade is to lemons what orange juice is to oranges and what pineapple juice is to pineapples made no sense to me.
Does it really make sense to you?
There’s Lucozade isotonic, which is supposedly for sporting types. The ordinary Lucozade seems to be the traditional remedy for those ill from the cold or flu (at least in our familiy).
Every time I use the term “jelly” to a British person, they assume I mean gelatin.
