Ingredients
½ cup granulated sugar
2 tablespoons water
2 tablespoons white vinegar
¼ cup light corn syrup (or honey as a natural alternative)
1 tablespoon minced onion
1 teaspoon mustard powder
½ teaspoon garlic powder
½ teaspoon salt
¼ teaspoon black pepper
¼ teaspoon paprika
1 teaspoon cornstarch dissolved in 2 teaspoons of water
Directions
In a small saucepan, combine the sugar, water, and vinegar over medium heat. Stir until the sugar dissolves completely.
Add the corn syrup (or honey), minced onion, mustard powder, garlic powder, salt, pepper, and paprika. Stir well to combine all the flavors.
Bring the mixture to a gentle simmer, allowing the onions to soften and the flavors to meld together.
Slowly whisk in the cornstarch-water mixture to thicken the sauce. Continue cooking for 1–2 minutes until the sauce reaches your desired consistency.
Remove the saucepan from heat and let the sauce cool to room temperature. For a smoother texture, strain the sauce through a fine mesh sieve.
Transfer the sauce to a clean jar or airtight container and refrigerate.
