Have you ever wondered what the difference between cake flour, bread flour, and pastry flour is? Is it ok to substitute all-purpose flour that call for a specific flour type? These are questions that I get asked often.
Choosing the correct flour is about controlling the amount of gluten in your dough. Gluten is a protein structure that makes dough both firm and elastic. Bread flour comes from “hard” flour, which has a higher protein content (produces more gluten) making it perfect for bread, pizza dough, and any recipe that needs a little more elasticity and cohesion.
Pastry flour is made with “soft” flour, which has a much less protein content and produces less gluten. Dough made with pastry flour is tender, flaky and doesn’t hold together firmly. That’s a good thing because no one wants a rubbery piecrust! Cake flour has even less protein content than pastry flour, but not by much. It has just enough protein to give the cake a little structure, but not enough to make it tough.
All-purpose flour is a blend of “hard” and “soft” flours, which falls in the middle of the gluten spectrum, and works well in most baked goods. Your cakes might not be quite as tender, but in most cases they’ll still come out beautifully. It’s all a matter of degree. Cookies, piecrusts, muffins, quick breads, and scones all do well with all-purpose flour.
Gluten development is also the reason why recipes instruct you not to over mix your dough. Once you add water or any other low-fat liquid to flour, gluten bands start forming and the more you knead or stir the dough, the more these elastic bands start connecting. If you are using all-purpose flour in a cake or piecrust, make sure to stop mixing just when everything comes together.

For mouth-watering breads that don’t require a lot of time, turn to quick breads. By using baking powder, baking soda, steam, or air instead of yeast to leaven dough. An advantage of quick breads is their ability to be prepared quickly and reliably, without requiring time-consuming skilled labor and the climate control needed for traditional yeast breads. Quick breads include banana bread, beer bread, biscuits, cornbread, cookies, muffins, cakes, pancakes, brownies, scones, and soda bread.
Almost all quick breads have the same basic ingredients: Flour, leavening, eggs, fat (butter, margarine, shortening, or oil) and a liquid such as milk. Ingredients beyond these basics are added for variations of flavor and texture. The type of bread produced varies based predominantly on the method of mixing, the major flavoring, and the ratio of liquid in the batter. Some batters are thin enough to pour and others are thick enough to mold into lumps.
There are four main types of quick bread batter:
Pour Batters: Such as pancake batter, have a liquid to dry ration of about 1:1 and so pours in a steady stream – also called a “low-ratio” baked good.
Drop Batters: Such as cornbread and muffin batters, have a liquid to dry ratio of about 1:2.
Soft Doughs: Such as many chocolate chip cookie doughs, have a liquid to dry ratio of about 1:3. Soft doughs stick significantly to work surfaces.
Stiff Doughs: Such as pie crust and sugar cookie doughs, have a liquid to dry ratio of 1:8. Stiff doughs are easy to work in that they only minimally stick to work surfaces, including tools and hands – also called “high-ratio” baked goods.
Preparing a quick bread generally involves two mixing containers. On contains all dry ingredients (including chemical leavening agents or agent) and one contains all wet ingredients (possibly including liquid ingredients that are slightly acidic in order to initiate the leavening process). In some variations, the dry ingredients are in a bowl and the wet ingredients are heated sauces in a saucepan off-heat and cooled.
During the chemical leavening process, agents (one or more food-grade chemicals – usually a weak acid and a weak base) are added into the dough during mixing. These agents undergo a chemical reaction to produce carbon dioxide, which increases the baked good’s volume and produces a porous structure and lighter texture. Yeast breads often take hours to rise, and the resulting baked good’s texture can vary greatly based on external factors such as temperature and humidity. By contrast, breads made with chemical leavening agents are relatively uniform, reliable, and quick. Usually, the resulting baked good is softer and lighter than traditional yeast breads.
Chemical leavening agents include a weak base, such as baking soda (sodium bicarbonate) plus a weak acid, such as cream of tartar, lemon juice, or cultured buttermilk, to create an acid-base reaction that releases carbon dioxide. Quick bread leavened specifically with baking soda is often called “soda bread.” Baking powder contains both an acid and a base in dry powdered form, and simply needs a liquid medium in which to react. Other alternative leavening agents are egg whites mechanically beaten to form stiff peaks, as in the case of many waffle recipes, or steam, in the case of cream puffs.
There are three basic methods for making quick breads, which may combine the “rise” of the chemical leavener with advantageous “lift” from other ingredients.
The Stirring Method: Also known as the quick-bread method, blending method, or muffin method is used for pancakes, muffins, corn bread, dumplings, and fritters. This method calls for measurement of dry and wet ingredients separately, then quickly mixing the two. Often the wet ingredients include beaten eggs, which have trapped air that helps the product to rise. In these recipes, the fats are liquid, such as cooking oil. Using mixing is done using a tool with a wide head such as a spoon or spatula to prevent the dough from becoming over-beaten, which would break down the egg’s lift.
The Creaming Method: Frequently used for cake batters. The butter and sugar are “creamed” or beaten together until smooth and fluffy. Eggs and liquid flavorings are mixed in, and finally dry and liquid ingredients are added in. The creaming method combines rise gained from air bubbles in the creamed butter with the rise from the chemical leaveners. Gentle folding in of the final ingredients avoids destroying these air pockets.
The Shortening Method: Also known as the biscuit method, is used for biscuits and scones. This method cuts solid fat (whether lard, butter, or vegetable shortening) into flour and other dry ingredients using a food processor, pastry blender, or two hand-held forks. The layering from this process gives rise and adds flakiness as the fold of fat melts during baking. This technique is said to produce “shortened” cakes and breads, regardless of whether or not the chosen fat is vegetable shortening.
Quick bread originated in the United States at the end of the 18th century. Before the creation of quick bread, baked goods were leavened with either yeast or by mixing dough with eggs. The discovery of chemical leavening agents and their widespread military, commercial, and home utilization in the United States dates back to 1846 with the introduction of commercial baking soda in New York by Church and Dwight of “Arm & Hammer” fame. This development was extended in 1956 by the introduction of commercial baking powder in Massachusetts, although the best known form of baking powder is “Calumet”, which was first introduced in West Hammond and Hammond, Indiana (later Calumet City, Illinois) in 1889. Both forms of food-grade chemical leaveners are still being produced under their original names.
During the American Civil War (1861-1865) the demand for portable and quickly made food was high, while skilled labor for traditional bread making was scarce. This encouraged the adoption of bread, which was rapidly made and leavened with baking soda, instead of yeast. The shortage of chemical leaveners in the American South during the Civil War contributed to a food crisis.
As the Industrial Revolution accelerated, the marketing of mass-produced prepackaged foods was eased by the use of chemical leaveners, which could produce consistent products regardless of variations in source ingredients, time of year, geographical location, weather conditions, and many other factors that could cause problems with environmentally sensitive, temperamental yeast formulations. These factors were traded off against the loss of traditional yeast flavor, nutrition, and texture.
