A dish can taste like childhood even after you learn it came from a packet.

Finding out how something was made does not undo what it meant. The taste belongs to a kitchen, a person, a time of day, and none of that was ever supplied by the ingredients. People sometimes feel cheated by this discovery, as though the memory had been counterfeit, but it was about being fed by someone who loved them. The packet is a fact about the shop, not about the childhood.

Having learned the origin of something you love, let both things be true. Make it again the way it was made. And when you feed people, worry less about provenance than about doing it at all.
