Yes, it was very good. 
Full disclosure: when I added the cheese to the roux, I let it get too hot, so the texture of the sauce turned grainy. It still tasted great, but I’m kind of fussy about texture. I’ll do better next time.
That’s just me. I associate it with summer, and hiking through the Lake District. You might like it any time of the year.
No problem. It was a staple in our home, but it was consumed mostly in summer. I cannot imagine it in winter, so we’re all good.
And to ThelmaLou–great! Like I said, it looked tasty, so I’m glad to hear that it was.
Yeah, that’s the myth I was talking about.
That’s why I shut off the heat as soon as I add the cheese. I’ll tell you what else will ruin it: low-fat cheese. You need the fat or it won’t melt right. I found that out the hard way.
Low fat cheese.
AKA fake food. Just say No.
Cheese and pickle sandwich isn’t a ploughman’s lunch - similar combo of ingredients but not the same meal.
What’s not to get! It’s just cheese + pickle in bread. It’s just a very popular British cultural classic, like your peanut butter and jello. The sweetness and tang of the pickle works great with the sharpness of the cheese. If you’ve got nothing else in the house, you’ll have some cheese and some Branston, so you can always whip up a simple sandwich for lunch.
Right.
If that was on purpose it was truly inspired. If not, it was still great. 
Potentially unpopular opinion here, but Branston isn’t that great. It’s not terrible by any means and it hasn’t fallen as far as HP sauce has.
Branston is reasonably representative of the style of a typical British chutney, but in maybe a rather ordinary sort of way.
There are nearly always better and more interesting offerings on supermarket shelves and especially places like farm shops. They’re not likely to be widely available outside the UK or often outside of their own region within the UK, because they’re not the big brand that Branston is.
I’m not saying Branston doesn’t deserve it’s popularity. It’s alright, but there are many better pickles.
