Patting the scallops dry before searing is crucial for achieving a good sear. Excess moisture will steam the scallops instead of allowing them to brown. Don't overcrowd the pan! If necessary, cook the scallops in batches to ensure they sear properly. Be careful not to burn the miso sauce. Reducing the heat to low before adding the sauce will help prevent this. For a richer flavor, use red miso paste. For a milder flavor, use white miso paste. Serve immediately for the best texture and flavor.
