Or you could cheat and buy the boxed ones from the crisp aisle, comes in packets of 3....you just pop one of the packets in the microwave and 3 minutes later you've got gorgeous pop-corn. They do 'em in both salty and sweet.
Then..........when ready, you fill a big bowl and open up the Body & Soul category and settle down for compulsive watching of the bickering which almost always happens at the weekend.
I've always used the packet ones and I like sweet and savoury. For savoury I have added a tablespoon of margarine melted in a seperate dish in microwave and then poured into the bag and shaken up a little. the most low-fat way is not to add anything to them but I can't quite manage that and have added a couple of squirts of honey or maple syrup when I wanted a sugar fix
