Ingredients

Scale

Main Ingredients:

  • 1 cup sugar
  • 1/2 cup water
  • 6 tablespoons (90 milliliters) white vinegar
  • 1 1/2 tablespoons (22.5 milliliters) red wine vinegar

Vinegars and Onion:

  • 1/2 tablespoon finely minced onion
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon garlic powder

Spices and Thickeners:

  • 1 tablespoon cornstarch
  • 2 teaspoons Dijon mustard
  • 2 teaspoons mustard powder
  • 1 teaspoon poppy seeds
  • 1/2 teaspoon sesame oil
  • 1/2 teaspoon salt
  • 1/4 teaspoon celery seed
  • 1/4 teaspoon paprika
  • 1/4 teaspoon black pepper

Instructions

  1. Combine all ingredients in a saucepan, ensuring thorough blending with a whisk to create a smooth, uniform mixture.
  2. Place the saucepan over medium-high heat, bringing the contents to a vigorous boil while continuously stirring to prevent ingredient separation.
  3. Maintain the boiling state for precisely 5 minutes, stirring consistently to develop a rich, cohesive flavor profile.
  4. Reduce heat to low, allowing the sauce to simmer gently for an additional 5 minutes until it reaches a slightly thickened consistency.
  5. Remove the saucepan from heat, letting the sauce cool completely to room temperature, which will further enhance its texture and depth of flavor.
  6. Carefully transfer the cooled sauce to a sterile, airtight container, sealing it securely for optimal preservation.
  7. Refrigerate the sauce, where it will maintain its quality and freshness for up to one week, ready to enhance your culinary creations.

Notes

  • Whisk ingredients vigorously to ensure smooth, lump-free sauce consistency and even flavor distribution.
  • Monitor heat carefully during boiling to prevent burning or scorching, which can alter the sweet onion sauce’s delicate taste profile.
  • Allow sauce to cool completely before refrigerating to help it thicken naturally and develop richer flavors.
  • Experiment with slight vinegar or sugar adjustments to customize sweetness and tanginess according to personal preference.
