Spiced sponge cake made in a traditional British style using raisins, currants, and spices to flavor a deliciously moist sponge made with carrots, potatoes, and suet.
1. Peel and grate the carrots and potatoes and set aside. Cover them with a damp paper towel to keep them moist and to prevent the potatoes from browning while preparing the other ingredients.
2. Add the milk, egg and sugar to a bowl and mix well to combine. Then add the shredded carrots, potatoes, raisins, and shredded suet to the bowl. Mix it all up well until combined.
3. Place a large sieve over the wet ingredients and add the flour, baking soda, and spices to the sieve. Use a spoon to push it through the sieve into the wet ingredients below. This helps to really combine the spices and baking soda and remove any lumps.
