Ingredients
Scale
Main Ingredients:
- 1 cup sugar
- 1/2 cup water
- 6 tablespoons white vinegar
- 1 1/2 tablespoons red wine vinegar
Seasonings and Spices:
- 1/2 tablespoon finely minced onion
- 2 teaspoons Dijon mustard
- 2 teaspoons mustard powder
- 1 teaspoon poppy seeds
- 1/2 teaspoon sesame oil
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
Thickening and Additional Spices:
- 1 tablespoon cornstarch
- 1/4 teaspoon garlic powder
- 1/4 teaspoon celery seed
- 1/4 teaspoon paprika
- 1/4 teaspoon black pepper
Instructions
- Select a medium saucepan and pour all ingredients together, stirring vigorously with a whisk to ensure complete and smooth integration of components.
- Apply medium-high heat, continuously whisking the mixture until it reaches a rolling boil, preventing any potential ingredient separation or lumping.
- Once boiling, immediately reduce heat to low, maintaining a gentle simmer while consistently stirring for approximately 5 minutes to develop a rich, cohesive sauce consistency.
- Evaluate the sauce’s thickness by observing its texture – when it coats the back of a spoon and shows slight resistance, remove from heat source.
- Allow the sauce to cool completely at room temperature, which typically takes 20-30 minutes, ensuring no residual heat continues cooking the mixture.
- Transfer the cooled sauce into a sterile, sealed glass container, securely closing the lid to maintain freshness and prevent contamination.
- Refrigerate the sweet onion sauce, which will remain viable and delicious for up to 7 days when stored properly in the coldest section of the refrigerator.
Notes
- Customize the sweetness by adjusting corn syrup or sugar levels to match personal taste preferences.
- For a healthier version, substitute corn syrup with honey or maple syrup for natural sweetening.
- Try white vinegar alternatives like apple cider vinegar for subtle flavor variations.
- Blend sauce smoothly by using a whisk or immersion blender to eliminate potential lumps during cooking process.
