Is there anything better than caramelized onions? The melt in your mouth texture, the sweet/savory flavor—I just love them. A few years ago I was looking for an appetizer using caramelized onions for a Christmas party; and when I couldn’t find one that suited me, I cobbled one together. I found one recipe that used figs, another that used Gruyere cheese, and a third that made the onions into small tartlets. I took these elements and used my go-to pie-crust recipe to make these tartlets using a standard muffin-tin.
