Edible Sedimentary Oolitic Limestone

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.

Let’s start with sedimentary, or more specifically, Oolitic limestone.

Oolitic limestone was formed in England in the Jurassic Period, and forms the Cotswold Hills, the Isle of Portland and parts of the north Yorkshire Moors. Rice crispies are a lot bigger than ooids, so when you’ve made your sticky marshmallow crispies limestone, you have to imagine that you’re looking at this limestone through a magnifying glass!

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

You will need:

100 gms Rice Crispies
25 gms butter
75 gms syrup
50gm marshmallows (cut up – handy hint – it’s best to cut the marshmallows with a pizza cutter or a pair of scissors)

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

Makes 15-20 limestone lumps.

  1. Weigh the butter and syrup directly into the pan, and melt gently over a low heat.
  2. Add chopped marshmallows and stir till melted.
  3. Working quickly, add the rice crispies and stir until coated, trying not to break the crispies. Once they’re coated, place spoonfuls onto a greased tray or Teflon baking sheet to cool. 
Top tip – this makes a quick and easy recipe for parties or a dessert.
