FAQs

Can I use yellow mustard instead of Dijon?

Yes, but the flavor will be milder and less complex. Dijon is preferred for its tang and depth.

Is this sauce spicy?

It has a mild to moderate heat level. You can adjust the cayenne pepper to control the spiciness.

What’s the best use for this mustard sauce?

It’s excellent as a dip for chicken tenders, fries, shrimp, or roasted vegetables, and also makes a great sandwich or burger spread.

Can I make this vegan?

Yes, substitute the mayonnaise with a vegan version and use maple syrup instead of honey.

Is it gluten-free?

Yes, provided your Cajun seasoning and mustard brands are gluten-free.

Can I use this as a salad dressing?

Absolutely. Thin it with a tablespoon of olive oil or water to make a zesty dressing.

How long does it last in the fridge?

This mustard sauce stays fresh for up to 7 days when stored in an airtight container.

What’s the difference between Creole and Cajun seasoning?

Creole seasoning often includes more herbs like oregano and thyme, while Cajun focuses on bold spices and heat. Either can be used here.

Can I freeze this sauce?

Freezing is not recommended, as mayonnaise-based sauces can separate and lose texture upon thawing.

Do I have to chill it before serving?

Chilling helps the flavors develop, but you can serve it immediately if needed.
