Can I make this sauce ahead of time?

Absolutely! In fact, making it a few hours or even a day ahead lets the flavors meld together, creating the ultimate creamy, tangy, spicy dip. Just cover and refrigerate until ready to serve.

Can I substitute Greek yogurt for sour cream?

Yes, Greek yogurt works beautifully as a substitute and even lightens up the sauce. The texture and tang will be slightly different but just as delicious. Plain, full-fat Greek yogurt is best for a creamy, rich result.

What can I do if my sauce is too spicy?

If you've gone a little overboard with the cayenne or horseradish, just add a bit more mayo and sour cream, mix well, and taste again. This will tame the heat quickly and bring everything back in balance.

Is it possible to double or triple this recipe?

Definitely! This sauce is a crowd-pleaser. Simply double or triple every ingredient, and be sure to use a larger bowl for mixing. It’ll keep for up to a week in the fridge, so it’s perfect for prepping ahead for a party.
