I basically learned by osmosis ie. cooking porridge and peeling potatoes for dinner as a kid and then occasionally taking over cooking duty as a teen. I don't remember the recipe books from Home Ec. Perhaps they were photocopied handouts.
But I do remember one old vintage book that may have been "Australian Home Cookery". It possibly once belonged to Granny.
Oh an egg flip! Is that a milkshake with an egg thrown in? Mum used to make a think called an eggflip with milk, milo, a raw egg and sometimes a scoop of ice cream (or just ice). I thought the name was made up and it was just an excuse to get some eggy protein into me (I was a not a big eater)
