Metamorphic Marble Fudge

By Fureya Nelson Riggott

FUREYA NELSON RIGGOTT made a fantastic geological recipe book in a previous Rockstar competition. Here we share three of her recipes to illustrate three different kinds of rock: one sedimentary, one igneous and one metamorphic.

This is the third, or more specifically, metamorphic marble fudge. Metamorphic rock is formed when limestone is exposed to high temperatures and pressures.

The word ‘marble’ comes from a Greek word meaning ‘crystalline rock, shining stone’. It comes from a verb that means ‘flash, sparkle, gleam’. This recipe mimics the crystalline texture of marble as well as the swirly patterns some marbles have.

Always make sure you have a responsible adult with you to help you prepare and bake your pancakes

You will need:

450 gm granulated sugar
75 gm butter or margarine
150 ml milk
175 can evaporated milk
2-5 ml vanilla flavouring
1 tsp cocoa powder
1 tsp instant coffee dissolved in
1 tsp boiling water

** Make sure you are not allergic to any of the ingredients!

  1. Lightly oil a 18 cm shallow square tin or line with Teflon baking sheet.
  2. Put the sugar, milk and evaporated milk in a heavy pan and heat gently, stirring until the sugar is dissolved.
  3. Bring to the boil without stirring, then continue boiling until a temperature of 116 degrees C (soft ball stage). Stir  occasionally to prevent sticking.
  4. Remove from the heat and pour about half into a bowl.
  5. Add vanilla flavour to one half and the cocoa and coffee to the other.
  6. Mix each one separately until each becomes thick and grainy. It helps to have a second person to mix the other one
    for you.
  7. Pour the mixes into the tray in two layers and use a skewer to swirl it so it looks like marble.
  8. Leave it to set, then cut it up into squares and admire the marble texture.
Top tip – this makes a delicious gift for someone you care about!
