Lightly oil a non-stick frying pan and fry heaped teaspoonfuls of the batter for 3 mins on each side. Keep warm while you use up the remaining batter – you should get 18 cakes altogether. (These can be made a day ahead up to this stage then chilled.)
To serve, heat the oven to 200C/fan 180C/gas 6. Arrange the cakes on a baking sheet and dot with a little tomato chutney and then a cube of mozzarella. Bake in the oven for 8-10 mins until hot and melted then pile onto a platter.
