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

  1. Select a medium saucepan and pour all ingredients together, stirring vigorously with a whisk to ensure complete and smooth integration of components.
  2. Apply medium-high heat, continuously whisking the mixture until it reaches a rolling boil, preventing any potential ingredient separation or lumping.
  3. 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.
  4. 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.
  5. Allow the sauce to cool completely at room temperature, which typically takes 20-30 minutes, ensuring no residual heat continues cooking the mixture.
  6. Transfer the cooled sauce into a sterile, sealed glass container, securely closing the lid to maintain freshness and prevent contamination.
  7. 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.
