Scandinavian food is amazing. Dill and fish. Last year me and my Dutch friend went to a fish restaurant in Copenhagen as her brother had bought her vouchers for it saying it was amazing. Turned out both of us were secretly dreading it as we are fish fans. But it was amazing. And yes I've had incredible meals in Stockholm before. Also see Iceland which isn't Scandinavian but was Danish controlled for many years. The fish and lamb there is out of this world. Both things that tend to be done terribly in the UK.
But with the exception of poffertjes and pancakes I'm with you with Dutch food (and my Dutch friend doesn't disagree!). Having said that the Dutch influence on Indonesia and vice versa is brilliant. You can get an amazing Indonesian which you can't in the UK in Indonesia.
I'm of the opinion that everywhere has amazing gems - you have to know what and where to go for it. The UK definitely isn't an exception. One of our strengths is our willingness and adoption of change and this manifests in fusion - the British are the best at fusion food. It's like culture - we steal so much and then claim it as ours! See the British curry - absolutely not Indian or Pakistani but definitely a part of British culture.
I have an American friend and my above mentioned Dutch friend who always want a British curry as they can't get anything similar in their own countries. And we are distinctly different to curries in India and Pakistan too because it's been developed for a British palate. The same goes for a Chinese. A British Chinese is mainly Hong Kong inspired but try and get anything similar in Hong Kong or China and you'll be hard pushed.
And as others have said - the humble potato certainly isn't a British thing. But we've made it our own. Fish and chips isn't British in origin. Nor are crisps. But there are definitely British crisps.
Same as British chocolate. Americans import it - because American chocolate is a special kind of hell.
And yes cheese.
Go live in Australia for a year and come back to me and talk to me about cheese. They don't cheese in the same way in part because cheese in a hot climate isn't a great mix. British cheese is incredible. We take it for granted.
And that's ultimately the crack. We take for granted what we can get and like a bad workman blame our own lack of skills for our 'poor cuisine'. It's bollocks we do world leading food in this country - that follows British traditions (that are ever changing).
Henry VIII would have a banquet with so many things we wouldn't recognise or would be disgusted by it wouldn't be able to source due to extinction. And this reflects the tradition of our country - to adapt to influences and changes in way that few other nations have because of our status as a naval island that's been outward looking and imported and that people have flicked to because it offered opportunities unavailable elsewhere.
Again. We take all this for granted. But it is our tradition. That has filtered to all levels of British society - fish and chips and a roast with potatoes are as working class as they are middle class....
