The MasterChef winner prepared some signature Asian dishes at Albury's wood-fired oven as the literary event wrapped up after five days on Sunday.

Festival co-ordinator Ann-Maree Ellis estimated 4500 patrons attended various sessions, with a capacity crowd of 250 hearing climate change proponent Tim Flannery on Friday night.

"It's been brilliant," Ms Ellis said.

"I do believe it has been our best ever, the vibe has been great.

"We're getting constantly good feedback from participants attending the festival and festival guests who enjoy the interaction and warmth of the intelligent, well-informed audiences."

Ms Ellis said it was apparent a "vein of pop culture fandom in Albury" had been tapped into through the opening night Dr Who-related play which attracted costumed audience members.

Liaw attracted questions ranging from which was the best wok to purchase to the type of cooking oil he preferred.

The law and science graduate who hosts SBS television's Destination Flavour, also discussed stress on MasterChef and the growth of portions in Australia.

"We've got very much a more is more culture with food," Liaw said.

"If we like a 150-gram steak, we're going to like a 300-gram steak more."

Speaking to The Border Mail later Liaw said he appreciated the audiences inquisitiveness as he prepared bun cha with nuoc cham and Khmer Krom barbecue chicken with dressed cucumbers.

"I tended to talk a lot about the science of the way I cook, that's just the way my brain works and I like to understand things that way," Liaw said. 

"Quite often audiences can glaze over at that a little, but what I loved was that people were really, really interested and the sheer number of questions I got."

Liaw does not want to use his profile to be dictatorial about food, a la paleo diet promoter Pete Evans.

"I don't want to be critical of the way anyone eats, we all try to do our best, sometimes if we don't eat as well as we might wish we do it's because we feel like we can't afford it or maybe we don't have the knowledge," Liaw said.

Sunday's festival events also included Albury author Dorothy Simmons launching her novel Living Like a Kelly.

The work focuses on Ellen Kelly, the long-lived mother of bushranger Ned Kelly.

"It's not a realistic novel in that it's not a chronology of events," Simmons said.

"It's looking at dreams and memories and how personal stories develop."

The novel involves a journalist taking shelter from a storm at Ellen Kelly's house and then unpacking the old lady's remarkable story.

Simmons said she had an affinity with Kelly because they both hailed from County Antrim in Ireland.
