Sodium bicarbonate is a crystalline solid compound that dissolves in water. It can be used instead of chemical products in recipes that require flavour enhancers or leavening agents. It acts as a gasification agent in pastry, bread, or biscuit recipes. It also helps pulses to cook and balances out acidity in sauces and stocks. What’s more, it is said to have properties that immediately relieve discomfort brought on by heartburn.
