Soak the tea bag in 300ml boiling water, remove the tea bag, then pour the tea over the fruit and leave to soak for 30 minutes.
Whisk the oil, sugar and eggs in a large bowl until pale and creamy, add the soaked fruit. Fold in the flour and pour into the prepared tin. Bake for 1-1¼ hours or until golden and cooked. Cool slightly before removing from the tin.
