A recipe in my files from long ago. Please let me know how it goes.
2 Cups rose petals
2 Tablespoons lemon juice
2 Cups sugar
1.5 Cups water
Wash rose petals well and remove the white part of the petals with scissors. Place petals into saucepan and pour in lemon juice. Over low heat, stir with wooden spoon until petals disintegrate. Remove from heat and place saucepan in a bowl of cold water because this will help keep the color bright. In a separate pan, combine sugar and water and bring to a broil over high heat. Pour the syrup over the rose petals. Over low heat, simmer about 10 to 12 minutes. Stir continuously until syrup thickens. Remove from heat and cool. Pour jam into small jars, cover and store or cover with paraffin wax and store.
