CaliToday (07/12/2025): The "Golden Rule" of grilling poultry: Put down the brush until the very end.
We have all been there. You are at a backyard barbecue, the smell of charcoal is in the air, and a platter of chicken hits the table. It looks perfect dark, glossy, and slathered in sauce. But when you take a bite, the skin is bitter and burnt, while the meat inside is disappointingly dry or worse, dangerously undercooked.

According to culinary experts, this common disaster stems from one simple mistake: applying BBQ sauce too early.
The Chemistry of the Mistake: The "Sugar Trap"
While a high-quality Carolina Gold or a classic Kansas City style sauce can elevate a dish, it is the worst possible additive during the actual cooking process.
Chip Carter, host and producer of "Where The Food Comes From," explains that slathering raw chicken with sauce before it hits the grill is a recipe for disaster. The reason lies in the ingredients. Most BBQ sauces are loaded with sugars molasses, honey, brown sugar, or ketchup.
The Science: Chicken needs significant time and heat to cook through safely. Sugar, however, burns rapidly at temperatures above 265°F (130°C).
The Result: If you sauce early, the sugar carbonizes long before the meat is cooked.
"It could totally ruin the chicken," Carter warns. "The sugars in sauces can go from delectably gooey and clingy to charred and something your guests will be surreptitiously spitting into napkins."
This creates a dangerous paradox for the cook: If you try to save the sauce from burning, you end up with "pink chicken" (raw meat). If you cook the meat fully, you end up with a burnt, acrid crust.
The Fix: The "Glaze Phase" Strategy
Does this mean you have to give up sticky, sweet BBQ chicken? Absolutely not. You just need to change when you apply the flavor.

To achieve that perfect restaurant-quality finish, follow the "90% Rule."
Cook the Chicken Naked: Grill or roast your chicken with just a dry rub (salt, pepper, paprika) until it is almost completely done.
Wait for the Finish Line: Only apply the sauce during the final few minutes of cooking.
The Glaze: As Carter suggests, use a thicker sauce. Brush it on or spread it with a spatula.
The Caramelization: Let the chicken stay on the heat for just 2–3 minutes longer.
This brief window allows the sauce to heat up, thicken, and "tack up" (stick) to the meat without crossing the line into burnt territory. This creates a perfect marriage of flavors where the sauce infuses the skin without destroying the texture.
Pro Tip: Use Marinades for Deep Flavor
If you are worried that saucing at the end won't provide enough flavor, you are confusing saucing with marinating.
Sauce is for the surface: It adds texture and a sweet/tangy finish.
Marinade is for the meat: To get flavor inside the poultry, soak the raw chicken in a marinade (a mix of oil, acid like vinegar or citrus, and herbs) for hours before cooking.
The Bottom Line: A marinade tenderizes the meat and adds deep flavor from the start. The BBQ sauce acts as the final "makeup" a glossy, delicious glaze added only when the heavy lifting is done.
