For Hot Cross buns, use the cinnamon roll dough recipe. Add some amount (just eyeball it) of candied fruit and currants when you are ready to shape the dough and make about twelve rolls. For Hot Cross buns, the egg wash is very important to give the right look. Whisk together a whole egg with a bit of salt; this is brushed on just before baking. You can use the other half of the egg or a previously saved egg white can be used.
