“How do you know when it’s done?” That’s one of the most frequent questions I get from novice Sun Oven users. A blank stare is the most common reaction to my usual answers : “When condensation builds up on the glass door.” “When in doubt I leave it in a little longer; it’s almost impossible to overcook most things.” or “I just kind of know.” However, sometimes you really need to know what’s going on inside the pot. And that’s exactly what a probe thermometer allows you to do. I wouldn’t even think of making Sun Oven roast beef, which I like rare, without one. I also use it for poultry, and especially turkey, to make sure it has cooked to a safe temperature.
Simple Solar Roast Beef
4- to 6-pound beef eye round roast
Let meat stand at cool room temperature for 45 minutes before roasting.
Set Sun Oven out to preheat.
Set roast, fat side up on a metal rack in a lidded roasting pan and sprinkle generously with salt and pepper. Insert the probe into the center of the meat. Add 1/4 cup water to bottom of roasting pan, cover and place in the Sun Oven. Cook until the thermometer reads 120ºF. Let roast stand, covered, 10 to 15 minutes before slicing.
