Applications for Baking Soda
A Quicker Way to Make Stock
•Aqueous NaHCO3 is alkaline •Decomposes to Na2CO3 + H2O + CO2
Traditional stocks require hours of cooking
•Rapid breakdown of pectin at pH > 5-6 weakens cell walls
Collagen slowly breaks down to gelatin
• Applications in the kitchen (polenta, oven roasted home fries, carrot cake)
