💡 Tips
- Use a rubber spatula to scrape every last bit from the bowl. This stuff is too good to waste.
- For the best flavor, let it chill in the fridge for 30 minutes before serving, even though it tastes great right away.
- Use full-fat mayo for the best creamy texture and flavor.
- Let it sit for at least 15 minutes before serving so the flavors blend well.
- If the sauce thickens too much in the fridge, a tiny splash of vinegar or water will loosen it up.
🔄 Substitutions and Additions
- Heat: Stir in a pinch of cayenne for a little heat.
- Relish: Swap sweet relish for dill if you prefer a more tangy finish.
- Pickles: Add chopped pickles for extra crunch.
- Citrus: A tiny squirt of lemon juice can brighten it up even more.
- Mustard: Use Dijon instead of yellow mustard for a slightly sharper flavor.
- Pickle juice: Add a splash of pickle juice if you want it a little thinner for drizzling.
Can I Use Regular Ketchup and Relish?
Of course, but it won’t be sugar free. If that matters to you, stick with sugar-free options.
How Do I Make it Smoother?
Use a food processor or mini blender if you want a super smooth consistency with no visible bits.
What if I Don’t Like Mayo?
This sauce is mayo-based, so that’s a tough one. You can try plain Greek yogurt, but it will change the flavor.
Is it Spicy?
Nope, it’s tangy and sweet. If you want heat, add a pinch of cayenne or a few dashes of hot sauce.
