Better Home Cooking Basics: #59 Don’t Throw Away Sprouted Garlic, Remove the Green Part Instead.
Have you ever found little green sprouts coming out of your garlic? I have & I've made the mistake of tossing it thinking it was bad. Turns out - it's not bad! Keep that garlic. Simply remove any green parts & then use it as you normally would. The green part is evidently super bitter. Or if you have a green thumb, I think you can plant the garlic in the ground once it's sprouted.
