Rub the top of a microwavable mixing bowl with (extra) butter. Place butter into bowl. Pour sugar directly on butter. Add salt and water.
Cook approximately 7-8 minutes (sometimes I have seen some microwaves take up to 12 minutes). Start watching at this point so as not to overcook. Candy is done when it's the color of a Heath bar or brown sugar.
Pour mixture over sliced almonds on a buttered cookie sheet. Don't scrape the bowl! Cool!
Top with melted chocolate (and more almonds if you wish) and let cool some more.
Break into pieces and serve. (I use a regular table knife -- just be sure not to cut into your cookie sheet!) Enjoy!
