Flour As Used in Baking

Flour PhotoFlour is usually the key ingredient in baking and much of pastry.  It is important to use the right flour for the desired outcome.  While flour can be made from various edible grains, for the purposes of this discussion I am going to stick with four types of wheat flour; all purpose, cake , bread  and pastry flour.  While bread baking can employ myriad other flours, these four are the basis of cakes and pastry.

What differentiates them is the protein count in each of them.  The higher the protein count, the stronger the flour.  You will see by the chart below, that bread flour is the strongest which makes it ideal for yeast breads that call for a strong flour to support the  expandsion provided by the yeast.  While bread can be made with all purpose flour, bread flour will almost always result in a higher rising, lighter loaf with a better texture.  On the other end of the spectrum is cake flour, which is very low in protein and has virtually none of the elasticity found in all purpose and bread flour.

Protein Counts for Flour:  Most flour is unsifted as used in current recipes.  It is best to stir it in the container, then measure.  Better yet, weigh it.  See Measuring for Baking http://pastrieslikeapro.com/2013/08/weights-and-measurements-in-baking/

                                Grams of                  Weight per       Weight per
Type of flour      Protein per cup            Cup, sifted      Cup, unsifted
Bread Flour             14 to 15        115 grams or 4 oz      140 grams or 5 oz.
All purpose flour     11 to 13        115 grams or 4 oz      140 grams or 5 oz.
Pastry Flour             9  to 10        115 grams or 4 oz.     140 grams or 5 oz.
Cake Flour                 6 to 8   100 grams or 3 1/2 oz      114 grams or 4 oz.

To Make Cake Flour:  Per one cup of all purpose flour, remove two tablespoons and replace with 2 tablespoons of corn starch.  Mix well.  This will lower the gluten content and make a softer flour.

To Make Pastry Flour:  Combine 2/3 cup all purpose flour and 1/3 cup cake flour to make 1 cup of pastry flour.

To Make Self Rising Flour:  Sometimes a recipe calls for self rising flour.  I don’t stock it in my kitchen and I bake a lot.  The main reason is I can’t control the amount of baking powder and salt in it.  It can easily be made by combining 1 cup all purpose flour, 1 1/2 teaspoon baking powder and 1/4 teaspoon salt for 1 cup.  Whisk together completely and use in the amount called for.

All purpose flour is a mixture of hard and soft wheat and comes bleached and unbleached.  It is used for breads, biscuits, quick breads, cakes and cookies.  Because the kernel and bran are stripped from the wheat when milled, the U.S. government requires iron, and four B vitamins (thiamin, niacin, riboflavin and folic acid) to be added to the flour to equal or exceed those found in whole wheat flour that is milled without stripping the vitamins.

Cake flour is milled from soft wheat and is always bleached.  It is very fine and silky in texture.  It is used for cakes and, in combination with all purpose flour, makes pastry flour.

Pastry flour falls between all purpose and cake flours.  We don’t get much pastry flour in our area so we make our own.  I use pastry flour for pie crusts and laminated doughs such as puff pastry.

Bread flour is made from hard wheat.  It is unbleached.

Bleaching flour can occur naturally if the flour is aged long enough or the flour can be chemically bleached.  Although I use unbleached flours, there is a problem if I am going to leave pastry dough in the refrigerator for a couple of days before using it.  If using unbleached flour, the pastry dough becomes gray.  There is not a problem with the taste or performance, just an off -putting color.  Bleached flour doesn’t become gray.

Pillsbury and Gold Medal are now made by the same company and the flours are virtually identical.  King Arthur flours are stronger which is why some people swear by the King Arthur Bread Flour.  Because it is stronger than other bread flours, it will support more expansion leading to higher loaves of bread.

In the south, they have a flour, White Lilly, which is a soft flour that I am told, makes the best biscuits in the world.   However, you wouldn’t use it for bread.   It is difficult to find outside of the south.

      Thanks Linda – so glad you found it interesting. Baking actually makes a lot of sense, but you have to know a lot about it before it does. We’ll be exploring more in the future.

    White Lily Flour is available at Straubs grocery stores in St. Louis and it does, indeed, make the most amazingly wonderful biscuits. Worth buying a bag just to make a batch of biscuits.
