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.
Potato flour: this is a flour, not a starch, made by crushing, grinding and dehydrating cooked potatoes. The flour is heavy and yellow-ish and has a strong potato flavour. It is generally used in baking where the end-product needs to retain moisture, such as bread or loaf cakes. On occasions, itâs also used to give a more potato-y flavour to a dish, such as potato soup. This too, is a gluten-free food.
