Combine the water, milk, yeast and sugar in the bowl of a stand mixer fitted with the dough hook attachment.
Allow to stand for 5 minutes until frothy then add the flour and salt. Knead on low speed until the dough starts to come together then pour in the oil.
Allow to knead for 5 minutes until the dough is soft and smooth. Cover with plastic wrap and allow to rise for 90 minutes in a warm spot.
Tip the dough out onto a floured surface. Press into a rectangle of approximately 1-2cm thick. Cut the dough into 12 rectangles.
Fold each rectangle in half then place in a baking dish lined with parchment paper. Cover with a tea towel and allow to proof for 30 minutes while you preheat the oven. Brush the rolls with egg wash before baking.
Pre-heat the oven to 180°C/350°F.
Place the rolls in the oven and bake for 20-25 minutes or until the rolls are golden and cooked through.
Combine the crushed garlic and melted butter then season with salt.
Take the rolls out of the oven and brush with the garlic butter as they come out of the oven and allow to cool for 10 minutes before serving.
