This is a very unusual, but pretty vinegar to make. It makes a lovely dressing for the milder salad leaves. Combine it with grape-seed oil as olive oil masks the flavour
Vinegar: Pack a clean jar with flower petals, making sure you have removed all green and white parts. Cover with a good white wine vinegar. Seal and leave in a warm spot for 4 weeks, shaking occasionally. Strain into clean, sterilised bottles.
Dressing: Place 2 tsp white sugar, 1 garlic clove, 3 tbsp violet vinegar and 9 Tbsp oil in a screw top jar. Shake well before using.
