Oh more raisin and currant jokes please.
Cake-baking is not like racism. But its cultural significance might be. A bit.
When people go 'oh god, it's just a farking road, who cares?!' about Whiteladies Road and Blackboy Hill in Bristol, they are, obv, just roads.
But their meaning is part of a cultural history, which leaves an aftertaste. So cakebaking is an act of cultural symbolism (which is why you Habbibu can have it mean summat different to someone else) no?
Tis just food, and being kind, and part of your household 'deal' that you're quite happy with.
But cakemaking has a wider set of meanings too. I seem to remember old Roland Barthes saying the same about a right load of old toss such as jeans, and red wine, and steak. It is never just 'food'. It is expressive of relationships. Food, sex and death are the usual anthropological battle grounds in 'how things are done' in social groups.
