- Consistency: The sauce should be thick enough to coat a cutlet but still easy to drizzle.
- Soy sauce: Use regular soy sauce for a stronger savory flavor or low-sodium soy sauce for a milder version.
- Mustard: Japanese mustard provides a sharper flavor, while Dijon mustard is a convenient substitute.
- Sweetness: Adjust the sugar according to your preferred level of sweetness.
- Worcestershire sauce: This ingredient provides important depth and tanginess.
- Cooling: The sauce becomes slightly thicker after cooling.
- Storage: Store leftover sauce in a clean, airtight container in the refrigerator.
