To avoid the flesh from discolouring, prepare avocados just before you serve them.

Step 1
Using a sharp knife, cut the avocado in half lengthways, carefully cutting around the fruit's large central stone.

Step 2
Twist the halves in opposite directions, until they come apart.

Step 3
Use a teaspoon to remove the stone.

Step 4
Carefully peel the skin away from the flesh with your fingers or with the tip of a knife.
