Leave the eggs out to warm to room temperature.
Heat the oven to 160 degrees centigrade.
Put the margarine and sugar in a heat resistant bowl and warm in the microwave (or water bath) to melt the margarin.
Add the grated ginger, honey and egg and mix.
When beaten with the mixer, fold in the flour with a rubber spatula.
Wrap the dough and leave to rest in the fridge for 30 minutes.
Take a small amount of dough in your hand and roll it into a ball.
Lay out the balls on an oven sheet, dust lightly with a little extra flour, and lightly flatten the balls with a fork or spoon.
Bake for 20 minutes in a 160 degree centigrade oven. (If the biscuits appear to be cooking unevenly, turn the tray around in the oven half-way through.) If you bake the biscuits longer they will be hard and crunchy. Less time will leave the centre slightly soft and moist and the outside crisp and crunchy. Bake to suit your taste.
