Method:

1. Make the batter by placing the flour into a bowl and whisk in the buttermilk if using (the butter milk gives a better flavor and lightness) then whisk in enough cold soda water to make a batter the consistency of pouring cream.
2. Preheat the veg oil in a large fry pan or wok.
3. Make the sandwiches by removing the crust off the white sliced bread. Butter one side of the bread then add your filling either jam or Nutella.
4. At this stage you can either cut the sandos into triangles or leave whole and cut after cooking either way it works. The triangles may help if the wok or pan is smaller.
5. Test the heat of the oil by dropping one of the crusts in and if it bubbles and sizzles it ready.
6. Dredge the sandos into the batter to coat well and carefully place into the hot oil and cook until golden on either side. Remove from the hot oil and drain well then place into a tray with the cinnamon sugar and toss well.
7. Serve while hot with ice cream.
