Possible Substitutes List & Recipe Variations
You can try some substitutes if you don’t have all the ingredients on hand. For brown mustard, use Dijon or spicy brown mustard instead. Honey works as a replacement for corn syrup.
No mustard powder? Use extra regular mustard. Apple cider vinegar can stand in for white vinegar. Worcestershire sauce is a good swap for soy sauce.
Want to change it up? Here are some tasty variations:
- Add 1 teaspoon of horseradish for extra kick
- Mix in 1 tablespoon of mayo for a creamier texture
- Stir in 1 teaspoon of sriracha for more heat
- Use maple syrup instead of corn syrup for a hint of sweetness
You can also adjust the spice level. Add more cayenne for extra heat or reduce it for a milder sauce. Play around with the flavors to find your perfect blend!
Remember to let your sauce sit for at least 4 hours before serving. This helps the flavors mix together better.
