Sift the flour and salt into a large mixing bowl, then make a well in the middle.
Warm the milk and water to around 115°F (46°C), then stir the yeast into the liquids until it's dissolved. Pour it into the well in the dry ingredients and mix a little of the flour into the liquid to create a thick batter. Sprinkle a little flour on top, cover, and let it rest until the batter is spongy, about 15 minutes.
While the dough is resting, cream the butter and sugar together until it's smooth and creamy.
Once the dough is spongy, add the eggs, brandy, orange rind, and a splash of water to it. Mix until the dough is elastic and a little sticky, then mix in the creamed butter and sugar until the dough is smooth.
Shape the dough into a ball, place in a large bowl, and cover with oiled plastic wrap. Set it in a warm, draft-free place to rise until it's doubled in size, about 1-2 hours.
While the dough rises, grease a large baking sheet for later use.
