To Make Violet Cakes
Ingredients
Directions
Prepare the violets
Remove leaves from the violets.
Beat the violets with lemon juice in a mortar.
Add double the weight of sugar to the violets.
Cook the mixture
Place the mixture in a saucepan over low heat, stirring gently until the sugar dissolves.
Avoid boiling to keep the color of the violets.
Drop the mixture onto a china plate.
Store
Store in a box with paper between each layer.

What each ingredient does
- Violets
- Provide the main flavour and the colour of the finished confection.
- Sugar
- Adds sweetness and, as it dissolves and cools, helps the mixture set.
- Lemon juice
- Adds acidity that brightens the flavour and helps beat the violets into a paste.
The step that matters
Heating gently without boiling. High heat breaks down the pigments in violets, dulling their colour. Gentle stirring over low heat dissolves the sugar fully so no grains remain to crystallise as the mixture cools.
