Baking 101: Leavening Agents Explained (2024)

FAQs

How do leavening agents work for baking? ›

A leavening agent is a substance that causes dough to expand by releasing gas once mixed with liquid, acid or heat. Rising agents give baked goods optimal volume, texture and crumb and can include baking soda or baking powder, whipped egg whites or cream, active or instant dry yeast, and even steam.

Baking Soda and Baking Powder: Chemical Leavening Agents

Some of the acidic ingredients that will activate baking soda are buttermilk, lemon juice, yogurt, sour cream, molasses, and honey.

Eggs, according to multiple sources, have a great ability to leaven or puff up foods when air is beaten into them,^{2, 3} and that they aid in leavening overall in baking applications.

Leavening Agents

Breads, cakes, cookies, and nearly all baked goods require a leavening agent. These are the key ingredients that make a cake rise. There are two types of leavening agents, chemical (baking soda and baking powder) and biological (yeast).

Raising agents

They create gas, air or steam which expands when heated and causes the food to rise. When heated, the gas that is trapped within the product expands. This is because heating causes the molecules in the air to move more rapidly and apply more force.

What is a leaven? A leaven is simply the agent that causes a bread or other baked item to rise. It can be a chemical agent like baking powder, or it can be a type of yeast, which is encouraged to fart out carbon dioxide to fill your dough with pockets of gas – the holes in the crumb.

The cream of tartar is a natural leavening agent, used in the kitchen and in pastry as a substitute for chemical yeast, especially suitable in case of yeast intolerance, but also for the preparation of vegan and vegetarian desserts.

Vinegar helps with the rise of our baked goods

Firstly, vinegar helps our baked goods rise and create an airy texture by reacting with baking soda. When vinegar reacts with baking soda, it creates carbon dioxide bubbles, which act as leavening agents.

Vanilla extract and how important is it for the baking process. The primary purpose of vanilla extract is to add flavour to baked goods. Lacking it, baked goods tend to have a bland and boring taste. Vanilla extract can also contribute moisture to create a soft and fluffy texture.

Why add one egg at a time when baking? ›

If you add your eggs all at once, you'll overwhelm the lecithin with too much water, creating a clotted mixture. The consequence of this un-emulsified batter can lead to tough cookies, lopsided cakes, and flat, dense muffins. So let's break down the proper way to add in your eggs, one at a time.

Baking powder and baking soda are added to breads and muffins, including quick breads that don't call for yeast. Any food with either of these ingredients is considered leavened. Pancakes, waffles, crepes, homemade cookies, cupcakes, cakes and brownies can also contain baking soda, baking powder or both.

Basically, all you need to know about baking is that the longer you mix a dough or batter, the stronger the gluten, and the more gluten, the better the chew. But you don't want the same chew from a beautiful cake as you would a baguette, so you minimise the development of gluten by not over-working the dough or batter.

Temperature's Role in Baking

Because ovens often fluctuate (or are incorrectly calibrated) a setting of 350° essentially ensures that the browning temperature is reached.

Baking powder is a two-in-one chemical leavening that combines a powdered alkali (sodium bicarbonate) with a powdered acid (originally, tartaric acid). When moistened in a dough or batter, a chemical reaction takes place that produces carbon dioxide gas, inflating cookies, cakes, and pancakes.

It is made from an alkali, bicarbonate of soda, and an acid, cream of tartar, plus a filler like cornflour or rice flour which absorbs moisture. The powder is activated when liquid is added, producing carbon dioxide and forming bubbles that cause the mixture to expand.

As with baking soda, the purpose of baking powder is to create air bubbles that give your baked goods their light, airy texture. There are two types of baking powder: single action and double action. Single action baking powder creates the carbon dioxide bubbles upon contact with moisture, similar to baking soda.

If you bake cookies without leavening agents, such as baking powder or baking soda, the cookies may not rise and will likely be dense and flat. Leavening agents help create air pockets in the dough, causing it to rise and giving the cookies a lighter texture.
