a) Airport congestion could be alleviated if federal regulations would allow airports to levy higher takeoff and landing fees for peak-hour travel. That would spread flights evenly throughout the day, making more effective use of existing capacity. The higher fees could then be used to build new capacity. In this case, less [federal] regulation is the answer. —Staff editorial, New York Times, June 11, 1990
b) The cooking methods we prefer are steaming and the so-called waterless method, where vegetables actually cook in their own juices. In both these methods, steam fills the space in the pan around the vegetables, so that oxygen can’t rob them of vitamins. Since the vegetables aren’t standing in water, the water-soluble B vitamins and minerals stay put. The small amount of liquid left after cooking vegetables by the waterless method should be kept and added to your vegetable stock supply.
—Laurel’s Kitchen (p. 179)
