Cameras and Tests. The three webcams I compared were the embedded webcam on my HP EliteBook 8760w; the Logitech HD Webcam C615, an external unit you can buy for under $40; and the Logitech Broadcaster, an external unit that costs around $200 (Figure 1, below).
Special cake flour with a high starch-to-gluten ratio is made from fine-textured, soft, low-protein wheat. It is strongly bleached, and compared to all-purpose flour, cake flour tends to result in cakes with a lighter, less dense texture.
1 You can substitute bread flour for all-purpose flour cup for cup. 2  Just remember the texture will be more chewy than with all-purpose flour. 3  Cake Flour has the lowest protein content which is why it is most commonly used in cakes. 4  Cake flour produces the tender crumb we desire in cakes. But for your information 1 cup of self rising flour has about 1 tsp baking powder and 1/2 tsp salt already mixed in. 2  With this knowledge you can make adjustments as needed. 3  You can also use this knowledge to make your own self-rising flour if a recipe calls for it and you only have all-purpose.
