Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3−). Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs.
Sodium carbonate is the inorganic compound with the formula Na2CO3 and its various hydrates. All forms are white, odourless, water-soluble salts that yield alkaline solutions in water. Historically, it was extracted from the ashes of plants grown in sodium-rich soils, and because the ashes of these sodium-rich plants were noticeably different from ashes of wood, sodium carbonate became known as "soda ash". It is produced in large quantities from sodium chloride and limestone by the Solvay process, as well as by carbonating sodium hydroxide which is made using the Chlor-alkali process.
Baking powder is a dry chemical leavening agent, a mixture of a carbonate or bicarbonate and a weak acid. The base and acid are prevented from reacting prematurely by the inclusion of a buffer such as cornstarch. Baking powder is used to increase the volume and lighten the texture of baked goods. It works by releasing carbon dioxide gas into a batter or dough through an acid–base reaction, causing bubbles in the wet mixture to expand and thus leavening the mixture. The first single-acting baking powder was developed by food manufacturer Alfred Bird in England in 1843. The first double-acting baking powder, which releases some carbon dioxide when dampened and later releases more of the gas when heated by baking, was developed by Eben Norton Horsford in the U.S. in the 1860s.
In cooking, a leavening agent or raising agent, also called a leaven or leavener, is any one of a number of substances used in doughs and batters that cause a foaming action that lightens and softens the mixture. An alternative or supplement to leavening agents is mechanical action by which air is incorporated. Leavening agents can be biological or synthetic chemical compounds. The gas produced is often carbon dioxide, or occasionally hydrogen.
Potassium bicarbonate (IUPAC name: potassium hydrogencarbonate, also known as potassium acid carbonate) is the inorganic compound with the chemical formula KHCO3. It is a white solid.
Potassium carbonate is the inorganic compound with the formula K2CO3. It is a white salt, which is soluble in water and forms a strongly alkaline solution. It is deliquescent, often appearing as a damp or wet solid. Potassium carbonate is mainly used in the production of soap and glass. Commonly, it can be found as the result of leakage of alkaline batteries.
Soda bread is a variety of quick bread made in many cuisines in which sodium bicarbonate is used as a leavening agent instead of yeast. The basic ingredients of soda bread are flour, baking soda, salt, and buttermilk. The buttermilk contains lactic acid, which reacts with the baking soda to form bubbles of carbon dioxide. Other ingredients can be added, such as butter, egg, raisins, or nuts. Quick breads can be prepared quickly and reliably, without requiring the time and labor needed for kneaded yeast breads.
Devil's food cake is a moist, rich chocolate layer cake.
Ammonium carbonate is a chemical compound with the chemical formula [NH4]2CO3. It is an ammonium salt of carbonic acid. It is composed of ammonium cations [NH4]+ and carbonate anions CO2−3. Since ammonium carbonate readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt. It is also known as baker's ammonia and is a predecessor to the more modern leavening agents baking soda and baking powder. It is a component of what was formerly known as sal volatile and salt of hartshorn, and produces a pungent smell when baked. It comes in the form of a white powder or block, with a molar mass of 96.09 g/mol and a density of 1.50 g/cm3. It is a strong electrolyte.
White chocolate is a confectionery typically made of sugar, milk, and cocoa butter, but no cocoa solids. It is pale ivory in color, and lacks many of the compounds found in milk, dark, and other chocolates. It is solid at room temperature because the melting point of cocoa butter, the only white cocoa bean component, is 35 °C (95 °F).
Quick bread is any bread leavened with a chemical leavening agent rather than a biological one like yeast or sourdough starter. An advantage of quick breads is their ability to be prepared quickly and reliably, without requiring the time-consuming skilled labor and the climate control needed for traditional yeast breads.
Buttermilk Crispy Tenders were chicken strips sold by the international fast food restaurant chain McDonald's in the United States and Canada. Chicken Selects were introduced in early 1998 for a limited time and offered again in early 2002 and late 2003 and then permanently starting in 2004. In the UK, they were launched on the "Pound Saver Menu", which offers various menu items for £0.99.
Monocalcium phosphate is an inorganic compound with the chemical formula Ca(H2PO4)2 ("AMCP" or "CMP-A" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCP-M"), Ca(H2PO4)2·H2O. Both salts are colourless solids. They are used mainly as superphosphate fertilizers and are also popular leavening agents.
Milk Duds are a brand of candies made with chocolate, created in 1928 by Hoffman and Company of Chicago and now produced and marketed by The Hershey Company, under license from owners of the brand, Highlander Partners, a Dallas-based global private equity firm.
Baking chocolate, or cooking chocolate, is chocolate intended to be used for baking and in sweet foods that may or may not be sweetened. Dark chocolate, milk chocolate, and white chocolate are produced and marketed as baking chocolate. However, lower quality baking chocolate may not be as flavorful compared to higher-quality chocolate, and may have a different mouthfeel.
Dry cocoa solids are the components of cocoa beans remaining after cocoa butter, the fatty component of the bean, is extracted from chocolate liquor, roasted cocoa beans that have been ground into a liquid state. Cocoa butter is 46% to 57% of the weight of cocoa beans and gives chocolate its characteristic melting properties. Cocoa powder is the powdered form of the dry solids with a small remaining amount of cocoa butter. Untreated cocoa powder is bitter and acidic. Dutch process cocoa has been treated with an alkali to neutralize the acid.

The old-fashioned doughnut is a term used for a variety of cake doughnut prepared in the shape of a ring with a cracked surface and tapered edges around it. While many early cookbooks included recipes for "old-fashioned donuts" that were made with yeast, the distinctive cake doughnuts sold in doughnut shops are made with chemical leavener and may have crisper texture compared to other styles of cake doughnuts. The cracked surface is usually glazed or coated with sugar.
Dark chocolate is a form of chocolate containing only cocoa solids, cocoa butter and sugar. Dark chocolate without added sweetener is known as bitter chocolate or unsweetened chocolate. As with the other two main types of chocolate, dark chocolate is used for chocolate bars or as a coating in confectionery.
