I suspect L&P would have been far too exotic for my parents (remember, my parents won't eat pasta because it's foreign). The line was drawn with salt and white pepper (I don't think I knew black pepper existed until I went to university, though as I came from a mining town in the East Midlands, I could say the same about black people). The cutting edge of exotic condiments was HP, which in those terms was furiously spicy. I'm not sure how that got an exemption, it's full of dangerously esoteric ingredients like garlic and tamarind.
I am blessed with a nostalgia for 80s era British food – a time when most things came in orange breadcrumbs and could be cooked in the oven. Fish fingers, crispy pancakes, you name it. I sailed with the good Captain Birdseye aboard the HMS Findus. Potato waffles, they're wafflely versatile. Even mash came out of the package after all, for mash get Smash, and frankly what kind of right-thinking Martian would peel a potato.
It wasn't all bland though, we had packets of Knorr parsley sauce.
