I'm English and have been making this for years, usually with blackberries, raspberries & blueberries and plain white sliced bread using one basin, like Guest 7. NO GELATIN ! The secret to the success of this dessert in my opinion is the weight on the covering plate which must sit on the pudding (I use cans of beans). I can't see how the weight on the coffee cups via a sheet pan would be sufficient. It's also a lot more trouble & fiddly than one pudding.
