Here is a link to a recipe that I have used since the 1970's. The cookbook is well used but many of the recipes are now online exactly as they are in the book. I actually stood by while my 14 year old granddaughter made it about a month ago.(She did it all herself!) Blueberry Cobbler. Simple to make, minimal ingredients and fast. I have made it with frozen berries when guests arrive too and I need a quick dessert. Great with a cup of tea.
