you didn't say where you used the fig jam, was it on one or both slices?

Given the amount of fig jam called for in this recipe, I'd put it on one side only. This will give you a nice layer, allowing the taste to come through on every bite.

By the way, how did I miss this recipe for bacon, pear, and brie panini? It sounds positively delicious! Glad you asked this question, and that I found this recipe!! ;o)
