In a bowl, mix the ají panca, oregano, salt, pepper, cumin, garlic paste, vinegar, and heart chunks. Allow to macerate, ideally overnight.
Slice the potatoes.
On the Instant Vortex control panel, press Air Fry, then set time to 12 Minutes and temperature to 355ºF (180°C). Press Start.
Once Add Food appears on the display, add potato slices. Close the tray and let cook.
When done, place the assembled kebab skewers on top of the potatoes, press Air Fry, and set time to 6 Minutes. You can turn them when there are 3 minutes to go. This means they have been cooked medium. If you prefer them well-done, add an additional 2-3 minutes.
To make these kebabs, you can also use the set of 5 kebab skewers and rack for Instant Vortex.
