Ingredients

Scale

Sweeteners:

  • 1 cup sugar

Liquids:

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

Spices and Seasonings:

  • 1/2 tablespoon finely minced onion
  • 1 tablespoon cornstarch
  • 2 teaspoons Dijon mustard
  • 2 teaspoons mustard powder
  • 1 teaspoon poppy seeds
  • 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

  1. Gather all ingredients and a medium saucepan to create a smooth, flavorful sweet onion sauce.
  2. Pour combined ingredients into the saucepan, mixing thoroughly with a whisk to ensure uniform consistency.
  3. Position saucepan on medium heat, stirring continuously to prevent ingredient separation or burning.
  4. Increase heat until mixture reaches a rolling boil, maintaining vigorous whisking for precise texture development.
  5. Continue boiling for 5 minutes, watching the sauce transform and thicken while keeping constant motion with the whisk.
  6. Lower heat to a gentle simmer, continuing to stir and monitor sauce consistency for an additional 5 minutes.
  7. Remove saucepan from heat source, allowing the sauce to naturally cool to room temperature without additional stirring.
  8. Once completely cooled, carefully transfer sauce into a sealed glass container with an airtight lid.
  9. Refrigerate sauce, which will maintain optimal flavor and texture for up to one week when stored properly.

Notes

  • Customize the sweetness by adjusting the sugar content to match your taste preferences.
  • Experiment with different types of onions like Vidalia or red onions for unique flavor variations.
  • Ensure smooth consistency by whisking continuously during cooking to prevent lumps from forming.
  • Create a healthier version by using low-sugar alternatives or natural sweeteners like honey or maple syrup.
