  • 1 tbsp cornstarch (or arrowroot powder)
  • 1 tbsp minced onion flakes
  • tsp Dijon mustard
  • tsp mustard powder
  • ¾ tsp celery salt
  • ¾ tsp fresh onion juice
  • 1 tsp poppy seeds
  • ½ tsp onion powder
  • ¼ tsp garlic powder

Instructions
 

  • Add sugar, cold water, vinegar, cornstarch, minced onion flakes, Dijon mustard, mustard powder, celery salt, and fresh onion juice to a small saucepan. Whisk until smooth and well-blended.
  • Place the saucepan over medium-high heat. Stir constantly as it heats up.
  • Once the mixture begins to bubble, reduce the heat to medium-low. Stir in the poppy seeds, onion powder, garlic powder, salt, paprika, black pepper, and sesame oil. Mix well.
