Cosmopolitan Bubbles (molecular gastronomy)

Impress your friends with this new way of serving your old favourites. I made these when Carly (one of the friends we made from My Kitchen Rules) flew to WA to visit us the other day. She thought they were great.

This technique (called spherification) is quite easy to master and can be altered to suit most cocktail recipes. This particular cocktail is one of my favourites. For more tips on spherification click here.

Ingredients

 Equipment

  • Stick blender
  • Jug
  • Measuring spoons
  • Dropper or syringe – optional (buy here)
  • Round silicon molds
  • Freezer
  • Slotted spoon (buy here)
  • 2 x containers

Method

  1. Measure out cranberry juice and add to jug.
  2. Add calcium lactate and blend with stick blender.
  3. Add vodka, Cointreau and lime juice – blend again.
  4. Taste and alter if required.
  5. Use dropper or syringe to fill silicon molds with cocktail solution.
  6. Place in freezer for 12 hours.
  7. 15 minutes before serving add sodium alginate to 2 cups of purified water. Mix quickly and well with CLEAN stick blender.
  8. Place in fridge for 15 minutes. This is your sodium alginate bath.

To make bubbles

  1. Remove sodium alginate bath from fridge (it should be more viscous that when you first made it).
  2. Fill container with 3 cups purified water. This is your washing bath.
  3. Remove frozen cocktails from freezer.
  4. Pop around four frozen cocktail blocks into the sodium alginate bath. Ensure they don’t touch (or they will stick to each other). Stir gently so all sides of ice blocks are in contact with the sodium alginate bath.
  5. Keep in sodium alginate bath for 3 to 5 minutes (the longer they stay in the bath the thicker the outside skin) or until ice block has melted.
  6. Scoop out using slotted spoon and rinse in water bath.
  7. Place in serving spoon and serve quickly.
  8. Repeat.
