hiya - about to brine muh bird. i know the salt needs to disolve but do i need to heat the liquid on the stove?

I'm also a convert dry brine fan. However, I've done wet brine and never heated the water. Just stir until the salt and sugar until it dissolves. That little gem comes from Alice Medrich of all people.

I never heat the water/liquid. Just give it all a little more time and stirring to allow the salt to dissolve. Warm water just speeds up dissolving, but you want the brine to be cold when you put the bird into it.

Yes, traditionally you'd heat the liquid and brine once it's cool. But we're also fans of the dry brine! https://food52.com/blog/8960-how-to-dry-brine-a-turkey
