In this episode of My Market Kitchen, Hort Innovation’s Research and Development Manager, Dietitian and Nutritionist Jemma O’Hanlon stepped into the studio at Prahran Markets to show Australians how to cook with custard apples and a range of Australian horticulture produce. Jemma creates a tropical immunity smoothie bowl packed with nutrients and travels to meet custard apple grower Daniel Jackson from the Glasshouse Mountains in South East Queensland.

Recipe: Tropical immunity smoothie bowl

Serves 2


1 Australian papaya
2 Australian passionfruit
Flesh of 1 Australian custard apple, seeds removed
½ Australian banana (use the other half for the topping)
2 tbsp coconut yoghurt

1 tbsp toasted coconut flakes
½ sliced Australian banana
2 tbsp Australian blueberries
2 tbsp Australian hazelnuts


  1. Slice whole papaya in half, scoop out the seeds and throw these away, then remove some extra flesh to create a deeper hollow. Keep the extra flesh
  2. Place papaya flesh and other smoothie ingredients in a food processor and blend until smooth
  3. Crush hazelnuts lightly in a mortar and pestle
  4. Pour the smoothie mixture into each of the papaya ‘bowls’, top with sliced banana, fresh blueberries, toasted coconut flakes and crushed hazelnuts.

Tip: When in season, swap the Australian custard apple for the flesh of 1 Australian mango, or 2 small Australian peaches, nectarines, apricots or plums. Swap coconut yoghurt for regular yoghurt for a protein boost.

Meet the grower from this episode

Daniel Jackson – Glasshouse Mountains, QLD

Nestled in the picturesque Glasshouse Mountains in Queensland, Daniel Jackson and his wife Angela grow custard apples and macadamias, with 1500 custard apple trees and 5000 macadamia trees planted at their farm. As well as managing the family business, Daniel is also the president of Custard Apples Australia which represents the industry and its 140 growers.

Recently they have also been working with The Department of Agriculture and Fisheries in Queensland to conduct a trial site as part of a Hort Innovation levy-funded project, to develop and evaluate new high yielding green and red skin custard apple varieties.

To find out more about the project and the Jackson family business, My Market Kitchen headed to the Glasshouse Mountains for episode 1 of our series. 

Investing in the future of the custard apple industry

Hort Innovation invests levy contributions from the custard apple industry, together with Australian Government contributions in the case of R&D, into Hort Innovation Custard Apple Fund initiatives to improve and grow the industry.
