My grandmother's one and only cake icing was a plain white icing that developed a thin crispy shell as it dried.
She only ever made yellow cake, with this icing and drizzled melted chocolate over the icing.
Cakes were reserved for special occasions.
Try as I might over the years I have not been able to replicate that thin crispy shell with the soft icing underneath.
She passed away before I could get her recipes written down. It wasn't 7 minute - it wasn't royal icing - it wasn't any version of a meringue I've tried. Not butter cream -
She was a pretty straight forward cook in the kitchen - learned to cook in the 1920's on a farm - nothing fancy - no pricey ingredients.
Does any one have a similar icing recipe?
