For the Popovers:

1. Preheat oven to 400 degrees F. and grease a popover pan. Set aside.
2. In a medium bowl, whisk together milk and eggs until smooth. Add salt, flour, and cheese. Whisk again until the batter is smooth. Finally, whisk in the melted butter. Divide the batter between the popover molds and fill each about 3/4 full.
3. Bake for about 25 minutes or until the popovers have reached a deep golden color. If you want the popovers to hold their shape, bake an additional 5 minutes or so but be careful not to burn them!
4. Remove and serve immediately if desired.

For the Blackberry Preserves:

1. Combine all the ingredients in a small saucepan and down until the blackberries have cooked down and the mixture has thickened.
2. Remove from the heat and transfer to a glass dish to let cool completely. Serve with the fresh popovers and enjoy!
