There are quite a few significant supply bottlenecks in the U.K. food supply chain, from supermarkets to wholesalers to importers, and they do allow for price fixing - demonstrably so in the case of supermarkets and domestic produce.
Also with a "big evil" you can tell yourself that removing that evil would solve everything.
I use housing as a good example since it's been a major driver of inflation and most houses are sold peer to peer on the open market. If you're selling your house and you see comparable houses selling for $900K, but you only need $750K to earn enough profit to buy your next house, what are you going to do? Sell for the lowest price you can afford? Or sell for the highest price you can get? You'd sell for the highest price. And that same calculation gets played out at every level of every transaction in every corner of the global marketplace. Yet nobody would think of themselves as being a villain for doing it. Or be accused of gouging.
The house sale is a perfect example, and is something to meditate on. (One solution is 'competition' such as making sure new houses are being built, other companies can produce food, etc.)
When a store runs out of flour, people don't get as mad at the store as if they raised the prices but keeps flour on the shelf. Despite the fact that having an expensive option for flour always leaves you better off than having no option.
After Hurricane Katrina there were some prominent examples of people being arrested under anti-scalping laws for trying to haul in food and generators from other areas to sell.
Companies are smart. When news gets spread far and wide about a shortage of eggs or other products due to disease or wars or "supply chain issues", they leap to take advantage of this consumer consciousness by increasing their prices, knowing the consumer will blame the larger macro factor and not the company. This has been well-documented, even in cases where the supply chain issues didn't actually impact the company that raised prices.
The best way to understand what's happening is via corporate earnings calls. They're upfront with their strategy when talking to investors.

I don't deny that corporations will try to make a buck taking advantage of favorable price-over-volume plays when they can, but I think it's crazy that people think during a global energy and fertilizer shortage Walmart just decided to throw out all of their low-price volume corporate strategy just to screw customers over egg prices.
I'd expect decent firms to not try to gouge customers who are already hurting at the time when they most are, but maybe "normal" means "sociopathic" in the context of amoral unrestricted capitalism
Couscous and margarine and eggs being more expensive across the board at the supplier level. This does not speak to any sort of cartel behavior.
