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.
Pastry Flour: Pastry flour is slightly stronger than cake flour, at around 9 to 10 percent gluten. It can be used for biscuits, muffins, cookies, pie doughs and softer yeast doughs. It has a slightly more off-white color than cake flour. One sifted cup of pastry flour will weigh just over 3Â½ ounces, or around 101 grams.
