When it comes to baking, the choice of flour can be just as important as the recipe itself. Two types of wheat flour commonly used in kitchens and bakeries are T45 and T55, each with unique characteristics that make them suited for various recipes. The classification of these flours is based on their ash content, which reflects the level of refinement and mineral richness present in the flour. This article delves into understanding these two widely-used flour types.
Understanding Flour Numbering: from T45 to T55
The Naming System
The ‘T’ in T45 and T55 refers to ‘Type’, a French system of numbering flours based on their ash content after incineration at 600°C. The higher the number associated with the ‘T’, the more bran and germ – and thus minerals – they contain. So T45 flour, being lower in number than T55, indicates a more refined product with less mineral content.
What does this mean for your cooking ?
Ash content may seem like an odd consideration when baking a cake or kneading dough, but it can significantly affect your results. More refined flours such as T45 produce lighter, finer pastries while less refined flours like T55 create doughs better suited for breads and pizzas.
Moving from understanding what these numbers denote, let’s delve into how these different compositions impact their use.
The Composition of Flour: ash Content and Gluten
Deciphering Ash Content
Ash content might sound confusing at first glance, but it simply indicates how many minerals are left after burning a sample – thus providing an insight into nutritional value and refining level. Dominated by calcium, potassium and magnesium, these minerals contribute to the flavour profile of your baked goods.
The Role of Gluten
Gluten content is another significant factor in flour selection. More refined flours like T45 have a lower gluten content and therefore yield lighter doughs suitable for delicate pastries. Comparatively, t55 with a higher gluten content allows for more robust doughs used in bread and pizza preparation.
Now we’ve looked at composition, let’s trace back the journey of these flours from field to mill.
The Grain’s Journey: from Cultivation to Grinding
Cultivation and Harvesting
The story of both T45 and T55 begins in wheat fields where farmers cultivate different varieties of wheat that will later be processed into various types of flour. The type of soil, weather conditions, and even the time of harvest can influence the quality and character of each grain.
From Grain to Flour
Once harvested, grains undergo several processes – cleaning, milling, refining – before being packaged as flour. During milling, grains are crushed to separate bran (outer layer) and germ (nutritious core) from the endosperm (starchy middle). This endosperm is then ground into fine flour.
It’s clear that the grain’s journey significantly influences the final product. Now let’s explore how these differences affect their use in cooking.
T45 vs T55: properties and Uses in Cooking
T45 Characteristics
- Fully stripped off its bran hence called ‘white flour’
- Ideal for delicate pastries like crepes or financiers due to its high degree of refinement
- Possesses a high glycemic index thus consumption should be regulated
T55 Characteristics
- Also a ‘white flour’ but slightly more whole than T45
- Better suited for breads, viennoiseries and pizzas
- Most commonly found in stores due to its affordability
Your choice between these flours will ultimately depend on the recipe at hand. Let’s look into how to select the right one for different recipes.
Selecting Flour for Breads, pastries, and Other Recipes
When to Use T45 Flour ?
The refined nature of T45 flour makes it optimal for delicate pastries. Its low ash content allows it to produce light-textured and subtly flavored baked goods perfect for high-end patisseries.
Why Choose T55 Flour ?
T55 flour, with its higher gluten strength and mineral content, is more suitable when baking breads or making pizza dough. It imparts a more robust flavor and texture that can stand up to heavier toppings or fillings.
The key lies in understanding your recipe needs. With this knowledge, let’s delve deeper into specific applications of T45.
When to Use T45 Flour and its Specific Applications
Dessert Type | Reason for Using T45 |
Crepes | Gives a light texture and delicate flavour due to lower ash content. |
Financiers | Allows for finer crumb structure perfect for these small French cakes. |
Puff Pastries | Fewer minerals interfere with gluten development, allowing pastries to rise better. |
With a deeper understanding of T45, let’s now focus on choosing the right T55 flour for your needs.
Criteria for Selecting a Suitable T55 Flour
Consider Your Recipe
Firstly, consider the type of recipe you’re preparing. If it requires a strong dough capable of holding heavier fillings or toppings, t55 is your best option.
Quality Matters
Not all flours are created equal. Look for T55 flours that are unbleached and contain no additives to ensure the best results.
Finally, where can we find these types of flour ?
Purchase Points and Buying Advice for T45 and T55 Flours
Where to Buy ?
T45 and T55 flours can be readily found in most supermarkets and online retailers. For higher quality options, sourcing from local mills or specialty baking stores may be fruitful.
Purchasing Tips
When buying flour, always check the expiration date and store in a cool, dry place to maintain freshness. Also, consider buying in bulk if you bake frequently as it can be more economical.
To wrap things up, whether you’re creating delicate pastries or hearty breads, understanding the key differences between T45 and T55 flours can greatly enhance your baking results. Remember to choose based on your recipe requirements and don’t be afraid to experiment with mixing flours – after all, great cooking often comes from playful experimentation.
