This caramel sauce from Torani is fun to use and tastes really good too. Even if you aren't a huge fan of caramel, this stuff can make your coffee creation or dessert a masterpiece.
I use it exclusively for coffee drinks and squeeze it directly on the foam when I make cappuccinos. The resealable cap protects the tip, which is easy to write with or make cute designs. The only drawback is that you will be getting caramel sauce everywhere, even if you are as careful as possible. You also don't need to use much, so this bottle will go a long way. I imagine it would also taste great on some ice cream or in hot chocolate.
This product can be a bit pricey, but it does contain many servings and it is a high quality caramel sauce that is not too thick and not too runny.
