I've used brie, chevre or any other soft round cheese for the Camembert if the Camembert is not available. This is a great crowd pleaser. You can even get these cheeses at Sams club for a decent price. And use a couple different jams for variety. Serve it with some fresh fruit along side and it will look like you spent hours!
Preheat Oven to 350*. Prepare a baking sheet by greasing lightly with Pam or line it with parchment paper.
Make sure you only cut through the rind of the Camembert cheese, run a knife around the top (1/4 inch in from the edge of the cheese). Make several cuts across the cheese forming small triangles, and then gently remove the top rind forming a shallow cup to hold the jam.
Spread the jam of your choice, I like raspberry or peach preserves or jam, depending on if you like seeds, over the top of the cheese. Sprinkle the rosemary and nuts on top. Place on baking sheet and bake 20 minutes or until the cheese is warm and soft.
Transfer cheese to a serving dish with a spatula. Serve with crackers or french bread toasts.
