Add the bicarbonate of soda to the
milk and gently stir into the cake mixture.
Grease a 20 cm (8") cake tin.
Pour the mixture in a place in a
preheated oven (180C/350F/Gas 4).
Bake for 1.5 hours.
If the top is getting too brown,
turn the oven down for the last 30 minutes.
Remove from the oven.
After 10 minutes, turn the cake
out onto a rack.
This is a very moist, rich ginger cake
that will last a fortnight. For an attractive topping, place a doily on
the cooled cake and gently rub icing sugar through a sieve, sprinkling
it over the surface of the cake. When you remove the doily, you will
reveal a lacy pattern.
