Rock cakes are basically individual portion size fruitcakes which got its fame from the Hagrid character of Harry Potter
Soften the butter and cream with the sugar and lemon juice until well aerated
Add eggs (ideal temperature - 23°C) in stages and cream well after each addition
Add the sieved dry ingredients - flour, baking powder and salt. Rub the mixture until it resembles bread crumbs.
Make a well and add milk and conditioned fruit, mix until just clear. Do not over mix
Hand drop onto tray to get 9 equal size buns and sprinkle with granulated sugar
Pipe in jam into a small hole on top of the bun. (Skip this step if you do not have bake stable jam. I didn't have any so I just applied jam on top of the cake while eating it).
Bake - Double pan at 210°C for 10-12 mins on Med oven settings.
Enjoy these rock cakes with some jam and butter when warm
