In a large bowl stir together the honey, molasses, cinnamon, nutmeg and cloves until well blended. Mix in the peel, almonds, brown sugar, orange and lemon zests. Stir the bicarb soda into the hot water then beat into the mixture along with the egg.
Gradually mix in the flour. The dough should be very stiff - you may need to knead it on the counter to get it thoroughly blended. Cover and chill overnight so the flavours can ripen.
Preheat oven to 180 degrees C. On a lightly floured surface roll the dough out to 1cm thickness. Cut into bars about 5cm long and 2cm wide. Place biscuits 3cm apart onto ungreased baking trays.
Bake for 12 to 15 minutes in the preheated oven until the bottoms are only starting to brown. Remove biscuits to cool on wire racks. Ice them with a thin glaze while they are still warm, if you like. When cool store in a tightly closed container.
