As I write this post, im here in Chennai India, for a vacation. Come here to spend time with my loved ones, and time for a very important milestone of life. Yes Im completing my 10 years of marriage, and I must share that it has been one helluva journey.Another thing that im juggling is organising a traditional south Indian pooja. This last 10 days has been so crazy with all the organising and Im just trying my best to keep my posts going… !
This post is all about using flour in baking.. Read on, or save it for later read
NEED FOR BASICS IN BAKING
This post here is something very basic and elementary. It is what every baker like you and me should know. Because its all about getting basics right with just enough knowledge.
I have always loved to bake and continue enjoying it. but all I did was to make recipes just blindly following it. I wanted to know more about what went into the delicious cakes, cookies, pies. All had the same basic ingredients, but a difference in the proportion made all the difference.
So i started to delve further in to the basics and started reading up a lot on baking ingredients. And I wanted to share the same thing here in a concise form. So it is helpful while any of you start on baking journey. And don’t have to keep scouring books and websites. Its all about flour in baking
In this post, I will take you through one of the most important and structural baking ingredient – The Flour. Its types and its role in baking.
Flour is a very generic term used in baking. It has various types, forms. Each kind of flour has its own properties. These properties will make us decide which kind of flour to use for which recipe or type of baked goodie.
As a baker we need to know what is flour, kind, properties and functions..
So let me warn you a little bit, its more theory, So that we get the basics right and strong.
WHAT IS FLOUR
Flour is any grain, pulse, cereal or nut that has been milled to a powder consistency to be able to use in any cooking or baking process.
In baking the most common flour is all purpose flour, (more on this further in the post). Flour is the most vital ingredient to baking, and is almost impossible to make bread & pastries without flour. Yes we do have gluten free options, but I am not going there now.
The four most important functions of flour to a baked product is
- Providing texture & appearance ( which comes from the kind of grain, strength of flour & types of flour)
- Contributes to the flavour ( depending on the grain used, types of milling)
- Provides nutrition ( most grain flours have protein carbohydrates, and becomes essential part of nutrition)
- Acts as a binding agent – as it absorbs liquid and helps in binding and bringing form to a baked product.
what kind of flour in baking
In baking, the most common kind of flour used is all purpose flour. The others being cake flour, self rising flour, bread flour, pastry flour. Then there are nut flours – almond flour, hazelnut flour.
Most common flours used by a bakeshop is pastry flour, bread flour and cake flour and all purpose flour. All these flours are categorised based on their milling and type of wheat used.
The All Purpose Flour that we use in baking, is a product of milled soft & hard wheat flours. So basically the flour that we use comes from wheat.
WHEAT FLOUR: the main grain
Wheat is the main grain, which is milled to obtain different types of flour for baking purpose. It is the most important ingredient in baking. It is the only grain that contains enough gluten forming proteins to provide the structure essential to baked goods.
To a novice baker, all purpose flour is good enough, but there are vareties of flour used for different baked goodies like pastry flour, bread flour. And to understand these, it is important to know the types of wheat which in turn contributes to the types of flour for baking.
The main characteristic of wheat flour depends on the type of wheat it is milled from. There are hard and soft wheat types,
TYPES OF WHEAT
- Hard wheat has more protein content, high in gluten content and contributes to strong flours. Primarily good for baking breads with yeast.
- Soft Wheats have fairly low protein content, resulting in less gluten and gives weak flours. These kind of flours are for cakes, cookies, pastries
Before going in to the kinds of wheat flour, a small run through the wheat kernel composition because this determine the kind of flour.
The Wheat kernel
the wheat kernel consists of the bran, endosperm and the germ
- The Bran – is the dark brown outer covering of the kernel, it is seen in form of brown flakes in whole wheat flours.
- Endosperm – this is the starchy part of the wheat, and gets the starch content from the endosperm. it contains the protein content. this is the part that is milled after removing bran and germ, giving white flour. this contains about 65 to 70 % of starch and 7 to 15% of protein.
- The Germ – this part of the kernel is high in fat. Flours containing germ spoils faster. hence these are sold seperately
the milling process breaks down the wheat kernel and almost 70% is milled into flour, separating parts of germ and bran. The current modern milling process is fairly complex. It needs to be understood, that repeated sifting and milling process, results in different grades of flours determining different protein content and strength content. on that note there is another very important characteristic that bakers must consider while selecting their choice of flour and that is determined by the protein content, and moisture absorption.
Here’s what you need to know ..!
- Protein content in the flour depends on the type of wheat. For example : To get high protein flour, milling must start with high protein wheat. Milling processes affect the grades of flour. The inner part of endosperm produces less protein than the outer part. So to get high protein flour, only the outer part can be milled.
- Another important point is water absorption, a higher protein flour will absorb more water and vice versa
- Ash content – is indication of the mineral content in a particular type of flour. Darker the flour colour, the higher is the ash content.
quick reference ..!
|FLOUR TYPE||protein content||ash content|
|straight flour||13 – 15%||0.4-0.45%|
|high gluten flour||14%||0.5|
|all purpose flour||11 – 11.5%||0.39-0.4%|
This basic information is enough for a baker to understand what type of flour to use in which baked good. This again, is determined by the protein content which results in high or low gluten flour. But basically these are all derivations from the wheat flour…
So here it is
TYPES OF FLOUR
- STRAIGHT FLOUR is made from the endosperm, and is the flour just after the bran, germ are removed. these go through various sifting processes to seperate the grade. when these grades are recombined, it is straight flour.
- BREAD FLOUR Is also called as patent flour, it is made from hard wheat and from the endosperm of the kernel. This flour is high in protein and good to bake breads and soft rolls. The protein content is around 12 to 15%.
- CLEAR FLOUR – it is the endosperm thats is left over after the patent or the bread flour is removed. this is darker in colour and usually used in rye breads.
- HIGH GLUTEN FLOUR – this flour has high protein and high gluten content, used in hard crust breads, pizza doughs and bagels. the usual protein content in such a flour is 14%.
- ALL PURPOSE FLOUR Is a blend of hard and soft wheat flours milled from endosperm. The protein content is usually around 8 to 12 %. This is commonly used by home bakers
- CAKE FLOUR is a soft wheat flour, with high starch content, low in protein, made mostly from the inner part of the endosperm. The protein content is around 6 to 9% and used in cakes, cookies.
- PASTRY FLOUR is also low gluten, low protein, made from soft wheat, but it is a little stronger than cake flour. the protein is usually 9%. Used in soft pastry doughs like pie, croissants, danish pastries.
This is all about flour in baking. Apart from this there are many other varieties of flours used by bakers, which are made of nut flours and other grains. More on that in some other post.
Thats all for now, on flour.
In the mean while, Have a good day.. !!
