Old fashioned fudge, it's the recipe from the cocoa container.
3 cups sugar
2/3 cup cocoa
1 1/2 cups milk
1/8 tsp salt
1/4 cup butter (no margarine)
1 tsp vanilla extract
Add first four ingredients to pan and heat to boiling on medium heat, stirring constantly. They say use a wooden spoon for candy making but I use regular spoons and it's fine. Once it starts to boil, turn down the heat and don't stir anymore, and never scrape the sides of the pan or your fudge will turn grainy from the crystallized sugar on the pan. The only thing I do differently is after it gets to the soft ball stage, I add the vanilla and butter (don't stir!) - then remove from heat and leave it for about half an hour. Letting it cool somewhat makes it a lot less work beating it with a spoon after. As soon as the fudge loses it's shine pour it, it sets up super fast. I don't mess around with parchment lined baking dishes, I do it like grandma did, I pour it onto a buttered plate.
