There are a lot of caramel recipes about how to make caramel from scratch if you want to do that. I used Smucker's topping because I had some on hand. I am not sure how homemade will perform in this recipe because store bought products contain more complex ingredients that might have made this recipe work. I did not add the bacon pieces to my syrup because I am using it for another instructable. Adding the bacon bits will add more flavor in my opinion.
1/2 Cup Smucker's Topping
2 Strips of fried bacon and reserve the bacon fat
1-2 Tablespoons bacon fat I used 2 rounded Tablespoons and could probably be safe with 3 but 4 might be stretching it, making it too oily.
Salt as desired
Wooden spoon, measuring spoons, measuring cup, jar with lid, and a heavy bottomed pan
