Make 1 dozen
Add dry flour all at once to boiling water and butter; stir quickly over the fire until mixture forms a ball which leaves the pan; remove from fire and stir till partly cool; add beaten yolks of eggs, part at a time, beating well, then slightly beaten whites; beat; set in cold place, covered, for 1 hr. or more; drop by spoonfuls about 2 in. apart on oiled and floured tin, flatten with brush or fingers dipped in milk (may leave without shaping); have oven rather quick at first, then slower until there is no "singing". Puffs are light weight when done. They will keep for several days. Reheat before filling. To fill, cut open at the side with shears.
The butter and flour may be creamed together first, and the boiling water poured over, then the whole cooked as before.
Cream - 1 pt. milk 2 eggs
1/2 cup sugar salt
1 tablespn. flour 1 teaspn.vanilla
Mix sugar and flour, pour boiling milk over, boil up well; pour over beaten eggs, return to fire until just creamy, not boiling, cool; add salt and flavoring.
If cream is preferred thicker, use 1/2 cup of flour and cook in double boiler 15 m. before adding the eggs.
Whipped cream may be used for the filling, but does not harmonize as well with the shells.
