I don't like store bought (orange)marmalades, at least in my country, they are congealed orange-coloured-but-barely-orange-tasting jams with random bits of peel floating at the top
However, my mum made it once, and I still remember it fondly, it was warm and syrupy and sticky and tasty, and it was perfect.
But we never made it again, it's such a god damn hassle.
Same with Ketchup, we made it a couple of times and it was amazing, but man, do these things take a lot of time and fiddling. Much easier to just buy off the shelf.
As my mother grows old and our generation has less time for dishes that take more than ~2 hours, I feel some of the charm has been leaving. We don't buy marmalade now, even though it's readily available.
