Place the peppers in the oven, either directly on the rack or on a piece of aluminum foil. Set the oven to 325F and turn it on.
Roast the red peppers, turning 3-4 times to blacken all sides, for about 60 minutes.
Place the roasted peppers in a paper bag and fold over the top. Allow the peppers to cool for about 20 minutes or until cool enough to handle.
Peel away and discard the blackened skin, the stem, and the seeds.
Place the peppers in a mini-chopper or blender.
Add the capers, salt, paprika, and Worcestershire sauce and blend until smooth. Serve over the grilled meat of your choice.
