Make It Your Way

Like it spicier? Add more red pepper or hot sauce. Too spicy? Cut back on Cajun seasoning use more Old Bay instead. Want it thinner? Splash in more stock. Thicker? Let it bubble bit longer. Sometimes add splash cream at end makes it extra rich. Everyone ends up making their own version - that's half fun!

What Goes Great With It

This sauce makes everything taste better! Dunk crab legs in it, pour over shrimp, drizzle on lobster. Even plain potatoes and corn taste amazing with this stuff. Make sure got plenty bread for soaking up every last drop - that's best part according my kids!

Keeping It Fresh
