I added garlic to my milk-based scalloped potato sauce and the garlic turned green! Is my dish ruined? Did it mold/curl ?

Here is the explanation, http://www.seriouseats.com/2013/08/ask-the-food-lab-why-does-my-garlic-turn-green.html

The short answer: the dish is not ruined and no, the garlic did not mold. It's safe to eat.
