Ingredients:
- 1 cup plain flour
- 1 tsp dry mustard powder
- pinch of cayenne pepper
- 1/2 cup butter, chopped
- 1 cup water
- 4 eggs
- 75 g Gruyère cheese (I used cheddar instead), chopped dice
- 1tbsp finely chopped chives (used dried rosemary)

Directions:
- Preheat oven to 200C. Lightly grease two large baking sheets. Sift together the flour, salt dry mustard and cayenne pepper.
- In a medium-size saucepan, bring the water and butter to the boil over a medium-hight heat. Remove from the heat and add the flour mixture all at one, beating with a wooed spoon until the dough forms a ball. Return to the heat and beat constantly for 1-2 minutes to dry out. Remove from the heat and cool for 3-5 minutes.
- Beat three of the eggs in to the dough, one at a time, beating well after each addition. Beat the fourth eeg in a small bowl and add a teaspoon at a time, beating until the dought is smooth and shiny and falls slowly when dropped from a spoon.
- Using two teaspoons, drop small mounds of dough 5cm apart on to the prepared baking sheets. Beat the reserved ett with 15ml/1 tbsp water and brush the tops with the glaze.
- Bake for 8 minutes, then reduce the oven temperature to 180C and bake for 7-8 minutes more, until puffed and golden. Transfer to a wire rack to cool. Serve warm.
