Cake Flour

Cake flour is made from extremely finely milled soft wheat. This results in an almost silky like texture and makes the best flour for more delicate bakes such as cake.

Another thing which makes cake flour the best for cakes and recipes of the like is the fact that the flour itself is bleached. This bleaching process results in a more acidic pH and alters the flour’s starches and fats. The increase in acidity helps cakes rise rather than collapse during the baking process. This, combined with the low protein content ensure that your cake is delicate and fluffy.

Ever since I started cooking I’ve been fascinated by how different people’s techniques are and how they best utilise the ingredients around them. Even the person living next door will have their own unique way of frying an egg or cooking a salmon fillet.

This fascination led me on a journey across the globe to discover the countless practices and traditions the world of cooking has to offer. I thought you’d enjoy and find value in sharing that journey with me so I created Cooked Best!
