I found a recipe for a gelatin desert I’d like to try. But there was one step I don’t feel prepared to tackle:
In the meantime, in a small sauce pan heat ¼ cup of water to about 100
degrees. Add the gelatin to the water and let dissolve.
I don’t have a candy thermometer to measure the temperature of my water. Would it be sufficient to use hot tap water? Or should I bring the water to a slow or full boil? Does the precise temperature make a difference when dissolving gelatin or is it ok to be rather approximate?
