Trim brussels sprouts and mark an X in the bottom of each brussels sprout to help cooking evenly. If using big brussels sprouts, skip this step, instead cut them in half or quarter.
Boil brussels sprouts in water seasoning with 1 tsp salt approximately for 10 minutes.
Drain brussels sprouts.
In a large sauteed pan, heat unsalted butter on medium high heat. Add minced garlic and brown them.
Add brussels sprouts and toss them with garlic to blend in the flavor. Add enough black pepper and adjust seasoning if needed.
Turn off the heat. Serve immediately and garnish with candied walnut (if desire)
