Some egg-wash substitute for glazing bread while bread-making :-
Soy Powder and Water: Make a vegan version of egg wash by using a mixture of soy powder and water.
Milk: For a golden crust, brush the dough with milk before baking. For a slightly sweeter glaze, dissolve a little sugar in warm milk.
Salted Water: For a light shine and a crisp baked crust, brush the dough with lightly salted water immediately before baking.
Honey: For a soft, sweet, sticky crust, brush a baked, still-warm bread with honey. Alternatively, try molasses or corn syrup.
Olive Oil: For both added flavor and shine, brush the dough with olive oilk immediately before and after baking.
Cornstarch: For a chewy crust, brush the dough with a mixture of cornstarch and water that has been cooked until translucent and then cooled.
