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.
Cake and rye flours are very similar in their weight measure. 1 cup (US) of cake flour is 100g and rye flour is 102 grams per US cup. Very similar, almost the same. Just convert into your units that you are most comfortable with. Cake flour: 100 grams (g) per cup Equals: 3.53 ounces (oz).
