Today is the first day of summer, and it just happens to be the hottest day of the year. Here in Taos, New Mexico, we are at 7000 feet and the temperature rarely even gets into the 90s. But after sitting in the sun for hours, my car's thermometer read 122 degrees. By the time I arrived home it had dropped to 100 degrees. The last thing I wanted to do was turn on the oven. The solution? Grilling hamburgers.
