Mozelle's Barbecue Sauce - A long-held secret family recipe, this is some of the best homemade barbecue sauce you'll ever have!

Mozelle’s Barbecue Sauce is a very special family recipe given to us by our good friend and neighbor Sean Cassidy, and we are truly honored to share it here today on A Family Feast.

(This is also one of two recipes we’re sharing today – so be sure to check out the Cassidy family’s award-winning Barbecue Pork Ribs recipe made with this sauce!)

Mozelle was Sean’s grandmother on his mother Emily’s side of the family. I had the pleasure of speaking to Emily in preparation for sharing today’s recipe, and I learned that Mozelle was a “true Georgia Peach” and also a great home cook!  Married to her high school sweetheart, always active and surrounded by life-long friends until she passed at the age of 94, Mozelle was a special lady and known not only for her fantastic barbecue sauce, but also for her pound cakes, fried chicken, soups, squash casserole, and sweet tea!

Here is a very precious photo of Sean and Mozelle:

As my husband Jack mentioned here, he pretty much pestered Sean for Mozelle’s barbecue sauce recipe all summer long so we could recreate it ourselves. But we learned that this barbecue sauce was a recipe that Mozelle kept secret and only shared with family!

Understanding what a treasure old family recipes are, we are so very appreciative that Sean (with his mom Emily’s permission) graciously shared it with us – and also allowed us to share it here on A Family Feast!

Like so many recipes from her generation – the ingredients in Mozelle’s Barbecue Sauce are all commonly-found ingredients that most people have in their kitchen.

But putting those ingredients together as she did – Mozelle’s magical barbecue sauce has the perfect amount of zesty, sweet, and rich tomato flavor that is absolute perfection on barbecued meats!  We’ve enjoyed this amazing barbecue sauce on pork ribs (see that recipe here), but the Cassidy family told us that Mozelle’s barbecue sauce is also delicious when making barbecue chicken as well.

P.S. Jack and I truly hope that we’ve done Mozelle’s recipes proud!  Thank you again to the Cassidy family for allowing us to share her recipes today.

    Just a question, im ashamed for ask, but you put the sauce before cook or after? And if after, what do you put in the meat to bake? Just Salt and pepper?
