This is a recipe of my Great Grandmother Annie that I came across in one our Family Cookbooks.
This is how it was written.
You will need a "snuff glass" for measuring !
Beat 3 yard egg, yolks in top of double boiler.
Add 2-1/2 cups milk & 1 cup sugar.
Fill a snuff glass half full of flour. Add water to make a paste.
Add water until snuff glass is 3/4 full.
Add a little milk mixture to flour mixture; then pour into milk mixture.
Add 1 tsp. vanilla. Put over boiling water,high heat. Add 2 tbsp. butter and cook until fairly thick.
Layer in bowl with vanilla wafers & sliced bananas. Top with meringue made with 3 egg whites and sugar. Brown meringue in oven.
