There are a ton of classic flavour marriages; little rules that you can follow, that even if you do not have the exquisitely trained palate of a French wine master, or the culinary knowledge of Michel Roux, will improve your food enormously.
When people "experiment" with food, they might make something OK, but might well make an absolute monstrosity of a dish. The chances of successfully making something half decent increase dramatically if you try and stay within certain boundaries, and trying to keep note of certain flavor marriages can help enormously. A simple example is a bit of boring old chicken? Classic partner? Mushrooms perhaps. A combo that exists in many cultures. Even Pot Noodle aren't stupid enough to ignore the chicken and mushroom combination.
Tomato and basil, smoked trout and horseradish, eggs and spinach, beef and carrot, scallops and black pudding, chicken and tarragon, and as the Germans all know, cabbage and pork. The dishes that tend to stand the test of time are generally based around some sort of classic affinity of flavours.
One of the reasons lots of people get into French cuisine is because it is often very much based around tried and tested combinations; not just ingredients cooked together, but the classic accompaniments to certain foodstuffs too.
Lamb with garlic and rosemary works super well of course, but alot of English people don't know that, being used to their mother serving up a bowl of rather acerbic mint sauce with the sunday lamb, and so they'll often experience a culinary orgasm the first time they are on holiday in France, and eat a
gigot of lamb, studded with a monstrous amount of garlic, and long woody stems of wild rosemary.
Far too many people, and chefs, waste stupid amounts of time trying to create new food marriages. Get's up my nose a bit really. Are they really arrogant enough to think that after hundreds of years of people cooking, that they are going to find some undiscovered gem? A combination of flavours that makes you go, "wow!". Not gonna happen much is it. I mean, chilli flavoured chocolate is a relatively new thing in Europe, and has that wow factor when you first try it, but FFS, those 2 flavours were being used together years ago in other parts of the world.
My point of view? If you think you've discovered a new flavour combination,
"something that shouldn't work but does!!", then it's likely to be either something that been invented before, or something that tastes utterly shit, but your tastebuds are too useless to notice.
