- Why did it collapse?
- Fat got into the foam (e.g. egg yolk or the bowl wasn't clean), which ruined the protein foam structure.
- It remained sticky.
- It didn't dry out enough, or the air was too humid. Sugar attracts water.
Meringue rings
The meringue ring is nothing more than dried egg foam. A miracle of physics: the egg white turns from a watery liquid into a solid, crisp foam by trapping air bubbles. The secret to success is not baking, but drying: at a low temperature the water evaporates whilst the sugar structure solidifies but does not caramelise (does not turn brown).

Instructions
1
✓
Start beating the egg whites with a drop of vinegar. When frothy but not stiff, add the icing sugar spoonful by spoonful.
Tip: The acidity of the vinegar helps stabilise the bonds of the protein molecules, making the foam stiffer.
2
✓
Beat until the foam is glossy, thick, and holds its shape on the whisk ('stiff peaks'). If you rub it between your fingers and don't feel sugar granules, it is ready.
Tip: The sugar must fully dissolve in the water content of the whites, otherwise it will 'weep' during baking.
3
✓
Fill into a piping bag and pipe rings onto a baking tray lined with baking paper.
Tip: Use a star nozzle for a ribbed surface, which dries better and looks prettier.
4
✓
Place in an oven at 80-90°C (fan oven is best), and dry for 1.5-2 hours.
Tip: Prop the door open with a wooden spoon so humidity can escape. We want to dehydrate (dry out), not bake.

✓
It is ready when it separates easily from the paper and makes a hollow sound. Leave to cool in the switched-off oven.
Tip: Sudden temperature changes can cause cracking.
