This recipe is inspired by the traditional Thai Tom Yam Goong. In addition, the idea of tom yam cavier came about when I was watching my daughter happily playing her colourful Orbeez (small, round clear colour balls made from superabsorbent polymers) with her play syringe.

The Tom yam cavier is an interesting way to add a touch of molecular gastronomy to this appetiser. I  simply use the cold oil spherification method to transform the tom yam soup into caviar-like spheres. Making this was so much fun, yet not difficult at all and it is tasty too!

This prawn dish is well balanced with the tangy, spicy tom yam cavier, fragrant lemongrass infused coconut cream and the refreshing sliced cucumber.

It is definitely an exciting dish to be served as an appetiser or starter to your guests at gatherings and parties.

  4. Stir till agar agar is dissolved into soup.
  5. Wait a few minutes until the temperature drops to 50-55 degrees. If the liquid is too hot, the droplets may not cool down enough and therefore not gel completely before reaching the bottom of the glass resulting in deformed spheres.
  6. Fill a syringe with the tom yam agar agar mixture and expel it drop by drop into the cold oil. The syringe needs to be high enough for the drops to sink when they get in contact with the oil but not too high or the drops may break into smaller drops creating “baby” spheres.
