When Duck Gets the Full Treatment: 10-Day Cures and 8-Year Starters
Some dishes on Diners, Drive-Ins and Dives are quick crowd-pleasers. Then there’s the Smoked Duck Sandwich—a creation that demands patience measured in days, not minutes, and a sourdough starter old enough to have its own personality.
“When that starter smells like an old bar, you know you’re doing it right,” the chef explained while mixing flour, salt, and an eight-year-old starter with bloomed yeast. Those house buns prove overnight, get shaped, prove again, and finally bake—a multi-day process before you even get to the star of the show.
The 10-Day Duck
The duck breasts receive a dry rub that reads like a spice merchant’s inventory: coriander seeds, garlic powder, dill seeds, salt, pepper, summer savory, and juniper berries. After the massage, they’re vacuum-sealed and left to cure for a full 10 days.

When cure time ends, the breasts hit a hot pan fat-side down to render, then transfer to a smoker running at 180 degrees with cherry wood and maple providing the smoke. The result? Duck sliced as thin as possible, warmed gently, and finished with that same spice mix from the original rub.
House-Made Everything—Including the Bacon
Because why stop at duck? The bacon gets the same meticulous treatment: garlic powder, salt, black pepper, long pepper, and brown sugar. Just that modest amount of seasoning, then another 10-day cure followed by 10 hours in the smoker. When Guy saw the setup, he offered to call his contacts at Camp Chef for a bigger smoker—the little unit was working overtime.
The bacon transforms into a warm cabbage slaw: belly cubed and rendered with butter and onions, deglazed with white wine, then tossed with cabbage for richness. Top that with homemade garlic-heavy mayo—”almost an aioli”—and you’ve got layers of house-made components that most restaurants would never attempt.
Guy’s Verdict
After that first bite, Guy didn’t hold back: “That changes the world of duck.” He praised the seasoning, the searing, the smoking, and especially the technique of thin slicing with a quick reheat. His final word? “Shut the front door, the back door, the side door, and all the windows.”
This kind of from-scratch commitment puts this sandwich in rare company alongside other labor-intensive DDD favorites like Mei Lin’s “98-Step” Hot Chicken Sando—dishes where the process is as impressive as the final product.
What You Can Learn From This Build
Cure time matters: Both the duck and bacon sit for 10 days with their dry rubs. That patience develops flavor you can’t rush.
Low and slow smoking: At 180 degrees with a fruit and maple wood blend, the duck takes on smoke without cooking too fast.
Slice thin, reheat gently: The duck gets sliced as thin as possible and just warmed through—preserving texture while serving it hot.
Build your slaw warm: Rendering bacon in butter, deglazing with wine, and folding in cabbage creates something richer than a cold slaw ever could.
