When I was a student, the local Sainsbury's supermarket in London had recipe cards by the entrance. It was easy enough to find everything in the shop. There were perhaps 30-40 cards to choose from.
This no longer exists, people probably look on their phones, but the restriction in choice was useful.
But this is the conundrum. If I can pick up a few ingredients, even if there’s some waste, and throw together a meal quickly the meal kits may not add much.
