Guy Fieri’s Blackberry Jalapeño Glazed Pork Tenderloin: A Tournament of Champions Masterclass
When Guy Fieri breaks down the technique behind his blackberry jalapeño glazed pork tenderloin, you know you’re getting real-deal cooking knowledge. This Tournament of Champions segment showcases exactly why this dish has become one of his favorites—and after watching the process, it’s easy to understand why.
The Magic of Sweet Heat
“Whenever you can get that juxta—the tanginess of a blackberry, the heat of the jalapeño, and anything that’s glazed, kids, families, everybody loves,” Guy explains. That philosophy drives every step of this dish, from the glaze to the brine to the final baste.
The glaze starts with blackberry preserves (about half a cup), jalapeños, and garlic that have been cooked down until they release what Guy describes as a “fantastic smell.” Then comes a cup of red wine—”Sonoma County’s finest”—which gets incorporated and reduced to concentrate those flavors.

The Brine Makes the Difference
What separates this pork tenderloin from ordinary preparations is the brining technique. Guy breaks down the science in straightforward terms: “A brine is a real simple solution—usually some salt and some sugar, a little bit of heat, and in this case it’s going to be a little red wine vinegar also.”
He explains the process works through osmosis, where the brine actually exchanges with the juices already inside the pork tenderloin. The brine gets cooked down similar to the blackberry glaze before the pork goes into a bag, sealed up with excess air removed. Even with just 20 minutes of brining time, the results speak for themselves.
“The brining—such a key piece to this because we’re incorporating some great flavor and some more moisture into that,” Guy notes. “Not that the tenderloin really needs it, but it’s just so fun to do and adds just that little extra kick of flavor.”
Building the Perfect Glaze
For the finishing glaze, Guy adds cornstarch to red wine as a thickening agent. “It’s just going to start tightening up—it’s starting to activate,” he explains while working. The critical tip here? Let the pork get a nice crust before adding any glaze, otherwise it’ll just sit there and burn.
The final product brings together blackberry preserves, jalapeños, garlic, and red wine, with the pork cooked to exactly 135 degrees. Guy’s commitment shows as he bastes the tenderloin repeatedly: “I’ll sit here and baste this thing all day.”
Tips from Guy’s Kitchen
Brine even when you think you don’t need to. The tenderloin doesn’t technically require extra moisture, but that flavor infusion takes it to another level.
Use cornstarch in wine for a quick thickening agent. It activates fast and creates that glossy, clingy glaze texture.
Patience with the crust matters. Wait for that sear before glazing, or you’ll end up with burnt sugar instead of caramelized perfection.
Cook to 135 degrees. That’s Guy’s target temperature for juicy, perfectly done pork tenderloin.
This blackberry jalapeño combination delivers the same kind of bold flavor profiles you’ll find in other Diners, Drive-Ins and Dives favorites, like Bone Marrow Tacos in San Diego or Bison Red Chile Fries in New Mexico—dishes that aren’t afraid to push boundaries while staying absolutely delicious.
