I do try to feed us few preservatives. I'm not fenatical (how do you spell this word?) about it, but I try wherever possible.
The other requirement I had was to be cheap. So, I whisked together (mixing after each new addition to the bowl) one egg, 1/4 cup of caster sugar, 3/4 cup of milk and a cup of self-raising flour. Spoon mixture into the pan, wait for it to bubble, flip it and a minute later you have pancakes. Couldn't be easier, couldn't be cheaper.
With this recipe so easy, don't get sucked into the pancake mix in the bottles. They have preservatives and additives to ensure dried egg-like substances last in the bottle. Of all the things to bake out of a packet, pancakes are just too simple to waste your money and possible health.
