Combine the sugar, salt, and a splash of water in a small saucepan, and set over medium/medium-high heat. Make sure the sugar is evenly moistened, the water helps it melt evenly.
Once the mixture starts to bubble, continue to cook for about 4-5 minutes. Monitor the sugar closely so it doesn't burn, turning down the heat if necessary, but you do want it to get nice and dark brown.
Remove from the heat, and add the butter to pan. Be careful as it will sputter. Stir it in throughly so that it's fully mixed together, the mixture should resemble a caramel sauce.
Slowly add the milk. The caramel mixture will harden up at first, this is fine, it will re-melt together as the milk heats up.
Set the pan over medium/low heat and slowly heat, stirring constantly, until the mixture starts steaming and all of the caramel has melted into the milk. Note: don't let the milk come to a boil.
Remove from the heat, and stir in the vanilla extract. Serve immediately, topped with frothed milk, whipped cream, or a sprinkle of cinnamon if desired.
