Having also lived in the US for varying (relatively short) periods of time, I can confirm the following from a European perspective.
1. American processed foods are indeed far sweeter than their Euro equivalents – including the bread that michaelm mentions.
2. The best "standard" peanut butter brand is Sun-Pat (always go for the crunchy variety and never the smooth). Stuff like Skippy, Goobers or Jif is an abuse in the sight of God and man... what do you expect from a nation that's happy to market marshmallow Fluff of various colours (note, colours, not flavours) in a jar?
3. There's not a good cup of coffee to be had anywhere in the US – well, not anywhere I've been, which includes amongst many other places allegedly authentic Italian restaurants in NYC and Starbucks flagship store in Seattle (from which I got barred, but that's another story). The problem seems to be that, when you ask for the darkest, richest roast, you get grounds that have been flash cremated far too fast and at far too high a temperature. What you need are beans that have been roasted slowly for a long long time, so that the flavour is allowed to develop. Hence why US coffee is invariably so insipid, thin and burnt-tasting – some things you should not and indeed cannot rush, regardless of the speed of life.
4. American chocolate is not chocolate, hence why you can't call it chocolate in Europe. It's more like candlewax, which is why, if you eat any, you'll feel like your entire mouth has been coated with a thin veneer of lard. Have you guys across the pond tried any European chocolate, especially Swiss, Belgian or French? I think your brains might explode at the unknown delight.
5. Americans don't understand cheese – again I suspect because proper cheese requires long and slow maturing times, entirely out of kilter with the "convenience-inspired" fast pace of US life. Native US cheese seems to come in two varieties, namely sickly white and vibrant yellow-orange. Both are flavourless, both would bounce if you dropped them and I suspect you could use a slice of either to effect a good temporary repair on a cycle tyre puncture.
6. Why don't you have kettles in the US??? How can you be expected to make a pot of tea without this kitchen essential? And don't go giving me that "Aaah but some houses have a boiling water tap in their kitchens" nonsense. How long has that water been heated? FFS
7. On the (single) flip side, your meat – and especially your beef – is normally of a very high and flavoursome standard.
PS Io, yes I absolutely use "in case" as well as "if" – there are nuances of difference between the two.
A. I won't visit tomorrow if you're ill.
That's a straight conditional – if you're sick, you won't see me, but if you're well, I'll be there. It's very definitely implied that I'll check first to see which of these either/or scenarios apply.
B. I won't visit tomorrow, in case you're ill.
I'm not coming round, regardless of your health. I've already decided this and am giving you the reasons for my forthcoming no-show. There's a doubt over your state of health, but my action is pre-defined regardless.
