Is it practical to brew with LME or DME in a keggle with something like the hopstopper installed. I am concerned about not being able to scrape the bottom with my stir spoon to prevent scorching. Is this even a concern? Just thought I would ask before getting a hopstopper.
Sure you can do it, after you have heated your water up enough to disolve your lme/dme turn off the heat and pour it in slowly while stirring. Once you have it disovled you can get the heat going again.
As an alternative, you could mix the extract and an equal amount of boiling water in a separate pot.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"

I dissolve my LME and/or DME in a gallon of water in a smaller pot while the water in the keggle is heating up. When it's well and truly dissolved, I add it to the keggle with stirring. So far, no problems with scorching.
