-
Preheat the oven to 210°C/425°F/Gas mark 7. Grease 2
baking trays.
-
Combine the butter and water in a large heavy-based
saucepan. Stir over medium heat until the butter melts.
Increase the heat, bring to the boil and then remove
from the heat.
-
Add the flour to the saucepan
all at once and quickly beat into the water with a
wooden spoon. Return to the heat and continue beating
until the mixture leaves the side of the pan and forms a
ball. Transfer to a large bowl and cool slightly.
-
Beat
the mixture to release any remaining heat. Gradually add
the egg, about 3 teaspoons at a time. Beat well after
each addition until all the egg has been added and the
mixture is glossy.
-
Spoon the mixture into a piping bag
fitted with a 1.5cm/5/8in plain nozzle. Sprinkle the
baking trays lightly with water. Pipe 15cm/6in
lengths onto the trays, leaving room for them to
expand. Bake for 10 to 15 minutes. Reduce the
heat to 180°C/350°F/Gas mark 4. Bake for another
15 minutes, or until golden
and firm. Cool on a wire rack.
-
Split each éclair,
removing any uncooked dough, and fill with whipped
cream.
Put the chocolate in a heatproof bowl. Bring a saucepan
of water to the boil and remove the pan from the heat.
-
Sit the bowl over the pan, making sure the bowl is not
touching the water. Allow to stand, stirring
occasionally, until the chocolate has melted. Spread
over the tops of the éclairs. Cool and serve.
