Ingredients
Scale
Main Sweeteners and Liquids:
- 1 cup sugar
- 1/2 cup water
- 6 tablespoons white vinegar
- 1 1/2 tablespoons red wine vinegar
Thickening and Binding Agents:
- 1 tablespoon cornstarch
- 2 teaspoons Dijon mustard
- 2 teaspoons mustard powder
Spices and Seasonings:
- 1/2 tablespoon finely minced onion
- 1 teaspoon poppy seeds
- 1/2 teaspoon sesame oil
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon garlic powder
- 1/4 teaspoon celery seed
- 1/4 teaspoon paprika
- 1/4 teaspoon black pepper
Instructions
- Combine all ingredients in a medium saucepan, using a whisk to blend thoroughly and eliminate any potential lumps.
- Place the saucepan over medium-high heat, stirring continuously as the mixture begins to heat and gradually reaches a rolling boil.
- Maintain constant whisking during the boiling phase to ensure smooth consistency and prevent ingredient separation.
- Allow the sauce to boil vigorously for approximately 5 minutes, watching for gradual thickening and reduction of liquid volume.
- Reduce heat to low, continuing to stir and simmer the sauce for an additional 5 minutes until it reaches a rich, glossy texture.
- Remove the saucepan from heat source and let the sauce cool completely at room temperature, which will further enhance its thickness.
- Once cooled, carefully transfer the sauce into a clean, sealed glass container with an airtight lid.
- Refrigerate the sauce, where it will remain fresh and flavorful for up to one week, ready to enhance sandwiches, salads, or other dishes.
Notes
- Customize the sweetness by adjusting the sugar levels to match your taste preferences.
- For a healthier version, replace regular sugar with honey or a low-calorie sweetener like stevia.
- Whisk continuously to prevent burning and ensure a smooth, silky texture throughout the cooking process.
- Store the sauce in a glass container to maintain its fresh flavor and prevent any plastic-related taste contamination.
