Coffee: 10ml coffee granules,
dissolved in 5ml boiling water
Method:
Preheat the oven
to l50"C/350"F /Gas 4. Base line and grease a
20cm/8in round cake tin.
Whisk the
eggs and caster sugar together in a heatproof
bowl until thoroughly blended. Place the bowl
over a saucepan of simmering water and continue
to whisk the mixture until thick and pale.
Remove the bowl
from the saucepan and continue to whisk until the
mixture is cool and leaves a thick trail on the
surface when beaters are lifted.
Pour the butter
carefully into the mixture, leaving any sediment
behind.
Sift the flour
over the surface. Using a plastic spatula, carefully
fold the flour, butter and any flavorings into the
mixture until smooth and evenly blended. Scrape the
mixture into the prepared tin, tilt to level and
bake for 30- 40 minutes, until firm to the touch and
golden. Cool on a wire rack.
