Forget all of the modern conveniences. “Time Machine Chefs” (8 p.m., ABC) asks four popular chefs to put themselves in the place of cooks for a feast in Tudor-era England and use only the implements available at that time. And don’t even think of relying on electricity or running water. Only the hardiest chef will impress the three demanding judges and walk off with the crown of “Greatest Chef in History.”
After going medieval, or close to it, some viewers may opt for the “Doomsday Survival” episode of “Extreme Chef” (9 p.m., Food). Seven chefs will be helicoptered into Salton City, Calif. — made to look like a post-apocalyptic wasteland. That must warm the hearts of the tourist board.
Participants are expected to scrounge as many supplies as they can. One intrepid cook uses tumbleweed, steel wool and batteries to start a fire. It’s not clear where they’re getting their food supply. But only one will survive the grim challenge and move on to the next “Extreme” round.
l Ready for yet another singing competition? “The Next” (8 p.m., CW) follows Gloria Estefan, Nelly, Joe Jonas and John Rich as they travel to different cities and spend 72 hours discovering local talent. Talents will perform and face elimination every week. Viewers will have the chance to vote one ejected singer into the finals. The winner will receive a recording contract from Atlantic Records when “The Next” concludes on Oct. 4.
