The finger lime industry had a problem of waste – until the pearls were identified as culinary jewels.
Finger lime food waste problem solved by Sunshine Coast award-winning restaurant
A farmer and chef have joined forces to prevent a culinary crime — by making sure delicious Australian ‘citrus caviar’ does not go to waste.
Out of the 50 kilograms of tasty native finger limes that Jade King recently picked for export to Italy, 15kg did not make first grade.
The shrubs protect their prized fruit with nasty thorns and Ms King said it was not uncommon for 10–20 per cent of the fruit to be either scratched as it grows, or odd shaped, creating a potential food waste problem.
“If we’re supplying export markets, our waste is significantly more, because you can’t actually include any fruit with scratches or marks on the outside, despite the fact that it is perfectly good inside,” she said.
“You may get odd-shaped fruit from pollination that hasn’t been totally successful.
“We’ve got others that are perfectly sized, beautiful fruit, but they’ve got a green tinge on the outside because they’ve been shaded by leaves.”
But instead of throwing out the ‘seconds’, Ms King approached the award-winning Spirit House restaurant at Yandina on the Sunshine Coast.
Head chef Aaron Tucker now buys between 1–2kg a fortnight, seasonally, using the fruit to add taste, texture and colour to his creative Thai dishes.
He described the flavour as ‘like a citrus caviar’.
“They’re a good substitute for traditional Thai lime pickle flavours.”
Green Valley Agriculture’s finger limes are currently gracing the Spirit House entree menu in a dish featuring Hervey Bay scallops with nam phrik phao, crispy rice, turmeric and finger lime kosho.
“We’ve been using [Jade King’s] product consistently for the past year and a half,” Mr Tucker said.
“It’s one of those ingredients that’s a good talking point for the guests and for staff to school them about this amazing product.”
Ms King said the feedback from the chefs was overwhelmingly positive.
“It’s really great to have that support from those chefs and they do some wonderful things and use them in ways that I wouldn’t have a clue about in their cooking and what they experiment with.”
Finger limes still grow naturally in the wild and are native to rainforests on the border ranges of south-east Queensland and northern New South Wales.
Food waste concerns are also being tackled by one of Queensland’s first farms to plant the increasingly popular native fruit.
The Lime Caviar Company developed the world’s first frozen spoonable ‘finger lime pearls’ to reduce food waste and extend the shelf life of their product from two to three weeks to up to 12 months.
Margie and Ian Douglas now export the flash frozen product to Thailand and Hong Kong from their picturesque property in the Scenic Rim.
Ms King is also investigating value-adding opportunities but, first, her focus has been on catching up with her harvest and the trees in her orchard laden with tasty fruit.
