Hi X - try a violet jam as well if you like an old fashioned flavour:
1 cup violet blossoms tightly packed. Use the whole flower as the stamens are edible too....
1 1/2 cup water
juice of 1 lemon
2 1/2 cup sugar
1 pkg of powdered pectin
Put blossoms, 3/4 cup of water and the lemon juice in a blender amd blend until you have a smooth violet colored paste.
Slowly add the sugar and blend until dissloved.
Mix pectin and 3/4 cupof water in a sauce pan and bring to a boil. Boil hard 1 minute. Pour hot pectin mix into blender with the violet mix and blend for about another minute.
Pour quickly into jars and seal. You can store this in the freezer too...
For a violet sugar, layer violet flowers alternately with sugar, and leave to mature for a week - same as for vanilla sugar really...
Like lavender as well, violet is an old time flavour - use the leaves to make a cream cheese flavouring, add to mayonnaise, chop and use in tomato soup....try steeping the flowers in a vinegar - it goes all violety coloured and ahs a really delicate background flavour - great for salads!
Use them to flavour a sorbet, or a granita, add to ice cream - you can make a lot of things with flowers for nice subtle flavours....just chuck violet flowers onto salad leaves to impress the guests for the easiest use...
And to answer the Q - can you make Parma Violets? - quite straight forward - make a sugar paste - use powdered sugar, and knead it with a little gum arabic (buy 50g for about �1 - you can get it on the web or ) or gum tragacanth (get it from sugar craft suppliers) , add the violet as a syrup and roll into pellets. When dry - you have Parma Violet sweets...been done since the 15th century....
