Baking Powder
Used in baking cakes, cookies, muffins and ofcourse biscotti. When you add water tobaking powder, the dry acid and base go into solution and start reacting toproduce carbon dioxide bubbles. When thebaked good is placed in the hot oven, the carbon dioxide production increase,give lift to the baked good.
Some baking powder contain wheat starch, whichwill be specified on the label. Glutenfree baking powder is available in most markets, and can be substituted inequal amounts.
Baking powder is available in two forms:
Single-acting baking powder produces all of itsbubbles when it gets wet,so you must bake recipes which include this productimmediately after mixing.
Double-acting baking powder produces bubbles againwhen it gets hot. Some gas is releasedat room temperature when the powder come in contact with moisture in the dough, but the majority of thegas is released after the temperature of the dough increases in the oven. So mixed dough can stand for a while beforebaking.
If you can’t find baking powder you can makeyou own.
Recipe for baking powder (gluten free).
In a small bowl sift together 2 tsp cream oftartar, 2 tsp cornstarch or arrowroot starch and 1 tsp baking soda. Make only a small amount at a time and store inan air tight container.

Baking Soda
Baking soda is a common leavener used in baking, cookies muffins and biscotti when certain ingredients are also included. Baking soda is pure sodium bicarbonate. When baking soda is combined with moisture and an acidic ingredient (e.g., yogurt, chocolate, buttermilk, honey), the resulting chemical reaction produces bubbles of carbon dioxide that expand under oven temperatures, causing baked goods to rise. The reaction begins immediately upon mixing the ingredients, so you need to bake recipes which call for baking soda immediately, or else they will fall flat!
Baking Powder and baking soda perform similar functions during baking, but they react differently with the other ingredients so you can't always substitute one for the other.
Yeast is not a common leavener when it comes to baking cookies, muffins or Biscotti but here is a bit about it anyway
Yeast
Yeast is made up of a single-celled organism, Saccharomyces cerevisiae, which multiplies rapidly when fed sugar in a moist environment. As a leavener, yeast also thrives on starch, which it converts to glucose, a simple sugar. This process ferments the sugar, which converts to alcohol and carbon dioxide. The carbon dioxide expands the baked good to produce the light, fluffy texture.
The minimal alcohol product burns off during the baking process, and the yeast dies also with the heat.
Tip: Salt inhibits the growth of yeast. Never mix yeast into salted water. However, if you are baking during the hot summer season and find your dough rising too much, the addition of a little extra salt can control that runaway yeast growth.
Most yeast is sold in single-use packets or bulk bags known asdry active yeast. If the dry yeast is stored in airtight packaging, in a cool dry place, it is not necessary to refrigerate it. Yeast should always be at room temperature to begin a recipe.
Also available isfast-rising active dry yeast, which is smaller-grained than conventional active dry yeast and speeds rising times by as much as fifty percent. It may be used interchangeably, measure for measure, with active dry yeast. Because of the speed at which it raises, fast acting yeast can be mixed t directly with the dry ingredients before adding liquid, instead of starting by adding it to warmed liquid.
Dried yeast has become the norm for its staying power in the pantry. But some still use compressed fresh yeast. This yeast as a 70 percent moisture and must be stored in the refrigerator. Compressed fresh yeast is highly perishable, as opposed to dry active yeast, and loses its vitality within 2 weeks, even when properly stored, refrigerated in an airtight container. You can store in the freezer, but should be defrosted at room temperature and then used immediately.
Compressed fresh yeast is difficult to find in the United States.
Tip: Yeast measures will also have to be adjusted at higher altitudes. Again, this will take experimentation on your part for your altitude.

FAQs
The possibilities are endless, but the common factor is the basic ingredients of fat, sugar, eggs, flour, liquid, leavening agent, and a flavoring ingredient. The flavoring might be a fruit or vegetable, a liquid such as buttermilk or fruit juice, an extract, herbs, or spices.
What are the 5 leavening agents used in baking? ›
leavening agent, substance causing expansion of doughs and batters by the release of gases within such mixtures, producing baked products with porous structure. Such agents include air, steam, yeast, baking powder, and baking soda.
What are the 4 leavening agents in quick bread? ›
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.
What are the 3 main leavening in baked goods? ›
Chemical leaveners (such as baking soda and baking powder) Organic leaveners (such as yeast) Mechanical leaveners (such as air or steam)
What are the 6 main ingredients used in almost all yeast breads? ›
2 The basic ingredients in a yeast dough are: flour, liquid, salt, sugar, fat, eggs and yeast. FLOUR: The flour used in making bread provides starch and protein, namely gluten.
What happens if you leave an egg out of bread? ›
Bread with no egg looked as normal as any other white loaf. It had puffed up evenly and had a nice crust colour and a soft texture. The interior was soft but quite tight. This could be made lighter by skipping the pre-shaping or folding steps making the dough looser.
What is the best raising agent for bread? ›
Compressed fresh cake yeast
– This type of yeast comes in a cake form. To use, simply crumble into dry ingredients or soften in warm water first. This type of yeast is known for its dependability and excellent rising ability. It is favored by artisan bakers.
What is the most common Leavener? ›
The most common leavening agents are: yeast, baking powder, baking soda, and cream of tartar. However, many other standard ingredients have some lifting qualities as well, such as: well-sifted flour, eggs, yogurt, beer, or seltzer water.
What is a natural leavener? ›
Natural Leaven
You'll hear “leaven”, “levain”, “starter”—it's all the same thing: wild yeast. Just flour, water, and microflora.
What are the 4 leavening agents used in quick breads? ›
Quick breads are leavened with by mixing sodium bicarbonate (baking soda) and acid (lemon juice, yoghurt). Quickbreads can also be leavened with baking powder (sodium bicarbonate + cream of tartar mixture). Quick breads made with baking soda will create gas bubbles as soon as liquid is introduced.
What is the most basic strengthener? Flour is the most basic strengthener used in baking.
Do all biscuits have to be rolled out? ›
DO ALL BISCUITS HAVE TO BE ROLLED OUT? No, some biscuits have more liquid and need to be dropped onto the pan or can be used as a dumpling in a soup or stew.
Is vinegar a leavening agent? ›
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.
What is the best leavening agent for cake? ›
Active dry yeast is what most recipes call for. It's a dry, granular yeast sold in packets or jars. Before working with it, active dry yeast must be activated, or "proofed," by dissolving it in warm water.
What is cream of tartar made of? ›
It's made from tartaric acid, a byproduct of the winemaking process. As grape juice sits and ferments, potassium bitartrate precipitates and forms crystals on the inside of the casks which can then be collected and processed to make cream of tartar.
What are quick breads made from? ›
Quick breads are prepared with flour, eggs, sugar, fats and liquids including milk, buttermilk, or sour cream, and each plays a part in the overall texture and flavor of the finished product. Flour adds structure to the bread but the batter must be mixed minimally so that the gluten structure doesn't develop too much.
What are the 5 types of quick breads? ›
All the best quick breads, including banana bread, zucchini bread, pumpkin bread, and cornbread recipes.
- Irish Soda Bread.
- Popovers and Yorkshire Pudding.
- Tortillas.
- Scones.
- Biscuit.
- Cornbread.
- Pumpkin Bread.
- Zucchini Bread.
Quick breads, unlike yeast breads, rise with the help of quick-acting leavening agents (baking powder, baking soda or a combination of both) and are generally baked as soon as the dough has been mixed. Quick breads can be savory or sweet, depending on the type of bread.
What is the chemistry behind quick breads? ›
Chemical leavening is used in quick breads, cakes, cookies, and refrigerated biscuit dough. Chemical leaveners produce carbon dioxide gas when water is added and/or in response to heat. Sodium bicarbonate is the base and source of C O 2 gas produced following a chemical reaction with acid.
