Store in a glass container or jar with a lid in the fridge for up to 2 weeks. To re-heat, scoop some out into a microwave safe bowl. This can be a little tricky because once it's cooled, it is very sticky of course. I usually use two metal spoons to spoon into a bowl. Then depending on how much caramel you need to warm up, I recommend just 10-15 seconds, stir, and then see how much more time you need.
