Seafood Showstoppers : Catch of the Day

In the mood for Barramundi grilled over coconut charcoal or Sumbawa Oysters? Karma Group’s award-winning Chef Joseph Antonishek shares recipes for these infused with an Indonesian delicacy known as torch ginger flower.  

Joseph says that they shop daily at the local fish market to ensure guests get absolutely the freshest local fish available on the Island. He explains that once the fish is unveiled in the kitchen, the magic begins in the precision butchering and the various preparations to follow.

‘One day, I was admiring the freshness of an 8kg Mahi- Mahi bestowed upon me. I thought to myself that our guests should see and experience the quality and freshness of the fish we serve. With a few sketches on the dupe paper from our kitchen printer, I designed a hand-carried mobile fish display which was brought to life by Robin in our engineering department.’

Joseph says the daily routine now consists of loading up our display with crushed ice, today’s catch, bottles of Karma Sparkling and Rose wine. We then proceed to the beach; in which our guests are individually presented with the beauty of the sea’s bounty! It’s a showstopper and appetite teaser to say the least.’

Torch Ginger Flower Butter

One of my favourite ingredients in Indonesia is torch ginger flower also called kecombrang in Bahasa Indonesia and bongkot in Bahasa Bali. It’s the actual flowering plant of the ginger root. It’s floral in aroma with a subtle spicy finish. This recipe will pair nicely with many uses, anything that ginger goes well with. To follow are two of my favourites!

    • Rinse the bottom shell under cold water and place on a sheet pan for holding.
    • Place 10 grams of torch ginger flower butter in the bottom of each shell.
    • Place an oyster back in each shell on top of the butter.
    • Strain the liquor through a fine sieve to remove any shell particles.
    • Evenly distribute the oyster liquor between each shell.

Some Chefs rinse the oyster flesh under cold water. I never do this too oysters. The unique flavour of each type of oyster comes from within the ocean or sound that they are harvested in.

By washing the oyster and discarding of the liquor you are essentially washing away it’s character. Instead, I hand select
each oyster and buy only the freshest best quality on the market!
