Polar bears are the largest land carnivores in the world, rivaled only by the Kodiak brown bears of southwestern Alaska. Polar bears are marine mammals, and spend much of their time on Arctic sea ice. Many adaptations make polar bears uniquely suited to life in icy habitats.
Baking soda has only one ingredient: sodium bicarbonate. Sodium bicarbonate is a base that reacts when it comes into contact with acids, like buttermilk, yogurt or vinegar. This reaction produces carbon dioxide (CO2) in the form of bubbles, like a liquid foam (think of the grade school experiments involving fake volcanoes, vinegar and baking soda). When making baked goods, the process is called âchemical leavening,â because the trapped CO2 gas makes the dough or batter rise. But when baking soda comes into contact with an acid, it pretty much reacts immediately. And thatâs a problem.
Use in Batter and Dough. Baking soda produces carbon dioxide bubbles, which help dough to rise. However, it only does this when mixed with water and acid. Cream of tartar is acidic and therefore serves as the acid to help baking soda rise. When mixed together and moistened, the two begin to form bubbles immediately. This means you want to get your batter into the oven quickly.
