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.
Subject: 3. What is the protein or gluten content of various flours? Cake flour is typically 7-9% protein; pastry, or cookie, ~9-10%; all purpose, 10-12%, bread, 12.5-13.5%, clear and high gluten, 14-15%; gluten flour (actually refined gluten), 45%.
