Check the weather: I really wouldn't choose a rainy or humid day to make divinity. The candy absorbs moisture from the air, which can make it difficult to set properly.
Use a candy thermometer: Getting the syrup to 260°F matters here. This isn't one of those candy recipes where I'd try to judge the syrup by eye.
Pour the syrup slowly: Stream the hot syrup gradually into the egg whites with the mixer running rather than dumping it in all at once.
Watch the texture, not just the clock: Keep beating until the mixture loses its glossy appearance and a spoonful holds its shape. That's a much better indicator than beating for a set number of minutes.
Work quickly once it's ready: Divinity starts setting fairly fast. Have your lined baking sheet, greased scoop and reserved pecans ready before you finish mixing.
Grease the scoop: A very light coating of nonstick spray makes portioning the sticky mixture much easier.
