While Ms Warren has assisted the likes of Matt Preston and Karen Martini at Festivale before, this will be her first time giving her own demonstration.

Ms Warren is a Melbourne-based freelance chef, who specialises in Catalan cuisine.

She has spent much of her career developing her own recipes as well as those used by Preston and Martini.

As well as Festivale, she has worked with the prominent food personalities on TV and for photoshoots.

"With Matt and Karen a lot of the time I'll get up on stage ... we've done festivals like this to backyard Bunnings type of demonstrations in West Melbourne," Ms Warren said.

"I'm always there and you can see me dancing around the demo. But actually holding and doing my own dish, in terms of delivering my own content, this will be my first time."

Ms Warren said while there wouldn't be too much difference in moving into the centre of the demo, there were things that she'd have to acclimatise to.

"I've done so many demos with Matt and Karen, the difference will be I'll have a mic and have to talk more," she said.

While Ms Warren admitted her dish wouldn't need an offsider helping with the cooking, a young apprentice chef would be on hand to assist.

Ms Warren has spent a significant part of her food career in Spain, particularly around Barcelona and the Balearic Islands.

Ms Warren said the dish she'll be serving up would be influenced by her Spanish-oriented culinary expertise.

"Having that content now out there in the world from my own experience and repertoire will mean I'll probably bring something a bit different to Launceston this year," she said.

"I think we [Festivale organisers] all sort of thought it would be nice to get a bit of Spanish cuisine on the agenda this year.

"Spain's quite diverse, gastronomically it's broken down into the regions and the historical influences of different cultures that have inhabited the country."

Ms Warren's dish will be rice-based and similar to a paella technique. The dish, translated to English, is ''dirty rice'' and is from her latest book Isla.

"A lot of people compare it to a risotto but it's very different to that, it's more slow cooking and slow food over on the [Balearic] islands," she said.

Festivale will run in City Park from January 31 until February 2. Ms Warren said being part of the event every year had been great.

"I'd love to come and work for them every year, it's great and I've met some great people because of it," she said.
