Ham and Cheese Puffs

Preheat oven to 400 degrees Fahrenheit.

Combine water, butter, and salt in a saucepan and bring to a boil.

Add the flour all at once, stirring vigorously, until the batter leaves the sides of the pan and a ball of paste forms.

Remove from heat and allow to cool for about a minute.

Add eggs, one at a time, beating vigorously after each one until the dough is smooth.

Stir in cheese, ham, and dry mustard.

Place heaping teaspoonfuls on a lightly greased baking sheet.

Bake for 15 to 20 minutes until firm and golden.

IF FREEZING: Allow to cool completely and store in an airtight container between layers of wax paper.
