Preheat the
oven to 350°F/180°C/gas 4. Butter two cookie
sheets.
Sift the
flour, ginger, baking powder, baking soda, and
salt into a large bowl. Stir in the brown sugar.
Melt the
butter with the corn syrup in a small saucepan
over low heat. Remove from the heat and let
cool. Stir the butter mixture into the dry
ingredients.
Add the egg
and mix to make a stiff dough. Form the dough
into twenty balls the size of walnuts and place
2 inches (5 cm) apart on the prepared cookie
sheets.
Bake for
12-15 minutes, or until just golden and firm to
the touch. Cool the cookies on the sheets for 5
minutes. Transfer to racks and let cool
completely.
