Man v. Food' was the biggest career-defining opportunity. I went from anonymity to someone of note with access to amazing eateries.

The Travel Channel had success with their 'Food Paradise' series, '10 Best Places to Pig Out' and those types of specials, so they knew there was a market for comfort food and wanted to develop a show around it.

My most memorable food challenge was probably the Big Texan in Amarillo. All the big executives called me because it was such an iconic challenge, and a victory in that would be a legitimizing device for myself as much as for the show.

If you do a quantity challenge, the problem you'd face would be a starchy challenge. If it has a lot of potatoes, a lot of bread or fried elements, that's difficult. With heat challenges, challenges that use the whole pepper are much, much easier than ones that use pepper extract. That's concentrated, and also devoid of flavour. It's just heat.
