Here is the text as it appears in the book:
through the ages, rose petals have been used as a flavoring in all sorts of dishes and drinks, puddings candies and preserves. One traditional recipe for a tasty rose-petal jam, calls for these ingredients:
8 ounces of petals, preferably taken from newly opened fragrant red or pink roses
1 tablespoon lemon juice
1 1/2 pounds sugar
1 cup rose water (available in pharmacies)
Wash and drain the rose petals. Dissolve the sugar in the lemon juice and rose water. Add petals and leave in a warm place to steep for a few hours. Put in a saucepan; simmer gently for 30 minutes, stirring frequently, until the mixture takes on a jam-like consistency. Allow to cool, then put in small glass jars and cover.
