"Ingredients
4 teacups flour
4 tablespoons caster sugar
2 teacups milk
2 whole eggs
2 teaspoons bi-carbonate soda
3 teaspoons cream of tartar
2 tablespoons melted butter
"Beat eggs, sugar and about half the milk together, add flour, and mix well together adding remainder of milk as required, also bi-carbonate and cream of tartar, fold in the melted butter.
Enough for 16 people
"Though the quantities are for 16 people, when there are fewer, I generally put in less flour and milk, but use the other ingredients as stated.
"I have also tried using golden syrup or treacle instead of only sugar and that can be very good, too.
"I think the mixture needs a great deal of beating while making, and shouldn't stand stand about too long before cooking."
And that's it!
I will add a photo when I have tried...
