Caramel sauce / Karamelni preliv

So today I decided to make caramel sauce. I thought it would be pretty easy, since all of the instructions I read were pretty simple. Boy was I wrong! It took me three times to perfect the recipe. The first time I didn't let the sugar change colour to a deep amber, so the ˝caramel˝ tastes like sweet vanilla pudding. The second time I tried to make caramel, I accidentally over burned the sugar (by just a few seconds!) and it tasted horrible. The third time, the caramel came out just the way I wanted. For my first try, I used the recipe from Fifteen spatulas, the second and third from Life and Kitchen. In the last recipe I didn't add the vanilla bean and it still turned out fine.
