Each brand is trying to find a way to get a leg up on the competition in a tight market space. The above picture is what I found on my last grocery run. What caught my eye was the asterisk next to the non-GMO popcorn claim. My guess was the ingredients list would include soybean, canola, or corn oil.
The temperature for broiling in an oven is 260 degrees Celsius or  500 degrees Fahrenheit. Medium heat is about 177 degrees Celsius or  350 degrees Fahrenheit.
Temperatures are higher for broiling than for roasting; the broil indicator of a household range is typically set around 550 Â°F (288 Â°C), whereas larger commercial appliances broil between 700 and 1,000 Â°F (371 and 538 Â°C). Fish, fowl, and most red meats are suitable for broiling.
