The sweetness of the sauce can be adjusted to personal preference—reduce the brown sugar for a more savory profile. Alternatives like unrefined sugar or honey can be used. For added depth, consider sautéing diced onion and bell pepper before browning the meat; remove them after softening, then stir them back in with the sauce. For enhanced flavor, extend the simmering time up to 30–45 minutes, stirring occasionally and adding water as needed to maintain consistency.
