Ingredients
Scale
Sweeteners:
- 1 cup sugar
Liquid Base:
- 1/2 cup water
- 6 tablespoons white vinegar
- 1 1/2 tablespoons red wine vinegar
Seasonings and Spices:
- 1/2 tablespoon finely minced onion
- 1 tablespoon cornstarch
- 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
- 1/4 teaspoon garlic powder
- 1/4 teaspoon celery seed
- 1/4 teaspoon paprika
- 1/4 teaspoon black pepper
Instructions
- In a medium saucepan, whisk together all ingredients until smooth and fully incorporated, eliminating any potential lumps.
- Position the saucepan over medium-high heat and bring the mixture to a vigorous boil, continuously stirring to prevent sticking or burning.
- Once boiling, reduce heat to low and maintain a gentle simmer for approximately 10 minutes, stirring frequently to ensure consistent texture and prevent scorching.
- Monitor the sauce’s consistency, which should gradually thicken and develop a glossy appearance; the mixture will coat the back of a spoon when ready.
- Remove the saucepan from heat and allow the sauce to cool completely at room temperature, which will further enhance its viscosity.
- Transfer the cooled sauce into a clean, sealed glass container with an airtight lid.
- Refrigerate the sauce, where it will remain fresh and flavorful for up to 7 days, ready to enhance sandwiches, salads, or other culinary creations.
Notes
- Customize the sweetness by adjusting the sugar amount to match your taste preferences.
- For a lighter version, replace some sugar with a low-calorie sweetener like stevia or monk fruit.
- Ensure constant whisking during boiling to prevent burning and create a smooth, consistent texture.
- Experiment with adding a splash of apple cider vinegar for extra tanginess that mimics Subway’s signature flavor profile.
