1/3 c. flour
2 c. milk
1 egg
3/4 c. sugar
1/8 tsp. salt
2 tsp. butter
1 tsp. vanilla
Moisten the flour with a little cold milk. Heat the remainder of the
milk and add the moistened flour. Cook in a double boiler for 10 or 15
minutes. Beat the egg, add the sugar and salt, and pour this into the
hot mixture, stirring rapidly. Cook until the egg is thickened, and then
add the butter and vanilla. Remove from the fire, cool, and fill into
the cream puffs.
