Use a sharp knife to carefully trim excess fat from the pork belly, leaving about 1/4 inch (6mm) of fat for flavor and rendering. Score the remaining fat cap in a crosshatch pattern to promote even rendering and crispy skin.
Trimming pork belly properly is crucial for achieving the desired texture and flavor. Here's a step-by-step guide:
Prepare Your Workspace: Ensure you have a clean cutting board and a very sharp knife. A dull knife will make the process difficult and potentially dangerous.
Assess the Fat Layer: Examine the pork belly. Ideally, you want a fat cap of about 1/4 inch (6mm). If the fat layer is significantly thicker, you'll need to trim it down.
Trim the Excess Fat: Using your sharp knife, carefully slice away the excess fat. Hold the knife at a slight angle, working in smooth, controlled strokes. Aim for an even layer of fat across the entire surface.
Score the Fat Cap: Once you've trimmed the fat, score the remaining fat cap in a crosshatch pattern. Make shallow cuts, about 1/8 inch (3mm) deep, without cutting into the meat. This helps the fat render evenly and creates crispy skin.
Inspect and Refine: Take a final look at the pork belly. Ensure the fat layer is even and the scoring is consistent. Trim any remaining uneven areas.
Don't discard the trimmed fat! Render it down to make lard, which can be used for cooking other dishes or even making soap. It's a great way to reduce waste and add flavor to your cooking.
