Place a clean saucer in freezer for 5 minutes. To check if jam has reached setting point, place a small amount of jam onto a chilled saucer. Place into freezer for 2 minutes or until jam is at room temperature. Run your finger through jam and wrinkle and if jam stays in 2 separate portions, it's ready to be stored. If not, cook for a little longer and retest.
Always use clean and sterilized containers to store jam. Keep it in cool place or refrigerate. It stays good for 2-3 weeks.
Use ripe papaya and apples to get the best results.
