In a jug mix milk, water, yoghurt and egg until smooth.
In a bowl mix flours and baking powder. Remove 1 tablespoon worth of flour mix and place into a smaller bowl, mix with 2 tablespoons worth of the yoghurt/milk mix to make a thin batter. Set aside.
Add the currants, cranberries, cinnamon, nutmeg, cloves, vanilla and sugar to the flour mix. Add the yoghurt/milk mix and stir to make a batter
Heat a frying pan over medium heat and add 1 teaspoon of the oil. Using the thin, small amount of plain batter you set aside, form three small crosses per serve in the pan. The pour a spoonful of the fruity batter over the top of each of the 3 small crosses and cook until bubbles have formed on the surface. Flip over and cook for another minute or so on the other side.
Repeat with the remaining oil, thin plain batter and the fruity batter until you have 9 hot cross pikelets.
