Fifteen cities around the country will be able to order ice cream on demand this Friday July 15.

It's the fifth year that the ride-sharing app has delivered ice cream, and this time they've teamed up with food rescue organisation Oz Harvest.

They worked with celebrity chefs Matt Moran, Neil Perry and George Calombaris to create ice creams using ingredients inspired by those that were salvaged and recycled, to draw attention to food wastage across the country.

Moran's Banoffee Crunch, Perry's Spiced Cookie and Salted Caramel Swirl and Calombaris' Caramel and Walnut Baklava will be available to order through the Uber app, and is $15 for a 500mL tub. Funds raised from tubs sold also provides meals to people in need.

Oz Harvest chef Travis Harvey worked with the chefs and Sydney's Serendipity Ice Cream to create 15,000 litres of the creations.

While it's not a week when Canberrans would normally be fighting over ice cream, with sleet and possible snow forecasted for parts of the territory on Wednesday, Harvey said there's never a bad time for the cold treat.

"Everybody loves ice cream and it doesn't really matter, if you go to someone's house for dinner and they offer you a beautiful ice cream after dinner, even if it's a cold night outside you're still going to say yes," he said.

And Harvey knows a lot about Canberra's temperatures, having grown up in the capital. He first qualified as a chef while working at former Canberra stalwart Tosolini's, and also went on to work at Aubgerine.

"Tina Tosolini taught me that you couldn't make her minestrone without cauliflower leaf and in fact that was one of the first really big lessons around thinking about what is food waste to some people," he said.

"She had to actually specially order them from our guy at the Fyshwick Markets. She'd ring up and say, 'I'm making minestrone, I need four shopping bags full of cauliflower leaves,' and without the leaves, it wasn't the same dish. So it was about thinking a bit outside the square."
