To Dry Flower Petals

Place the petals in a single layer on a foil-lined baking sheet and put this in the oven set at 100°C/200°F/ gas mark ¼ for about 2 hours or until the petals are dry enough to crumble. Store them in an airtight jar in a cool, dark place and use them as you would other herbs, within 12 months, until the flowers are in bloom again.
