We need to make a room. A room is a thickening agent made out of butter and flour. These are measured in a one-to-one ratio by weight. This is the same idea as the old joke. We'll raise more, pound a bricks or pound a feathers. They weigh the same, but they just have different volumes. There's three stages of cooking a room. White, then blonde, and finally brown. What changes during these different stages you ask? Well, think of it this way. The long you cook a room, the more flavor you develop, but the less thickening power it has. A white room has the least flavor, but packs the most punch in the thickening department. Although a brown room has a developed nutty flavor, you'll need to use more to thicken the same amount of liquid when compared to a white or blonde room. We're going to straddle the line between thickening power and flavor today and make a nice blonde room. Thank you for coming to my TED Talk.
