because baked has replaced jacket in every day use where I live
So, do you put your 'baked' on before leaving the house, or do you still wear a 'jacket'?
I ask this because your post implies that the word 'jacket is no longer used AT ALL and has been completely replaced by the word 'baked'.
In my (chef) son's world, a baked potato has been 100% baked in its skin, in the oven, whereas a jacket potato has been cooked (at least partially) in the microwave. This is generally why cafes, pubs and restaurants state 'Jacket Potatoes' on their menus and not 'Baked Potatoes'.
I generally do 'jackets' because I start them off in the microwave for a few minutes to soften the centres and finish them in the oven or airfryer (with is basically a mini oven) for the crispy skin, but occasionally (if I've got time to spare) I'll put them straight into the oven raw, and bake them throughout.
