Pre-heat oven to 180°C / 350°F / Gas Mark 4.
Prepare fruit as appropriate: wash, peel, core and slice up apple; wash and slice rhubarb; rinse other fruits and de-stone as appropriate.
Place prepared fruit in a pan with a very little water to only just cover base of pan.
Add honey and simmer on a moderate heat with lid on pan for approx 6 minutes until softened. If you do this gently the juice from the fruit will create lovely juices. Do not let the fruit dry out - it should be very juicy. Add a little more water if necessary. Taste and add more sugar if required - you will certainly need more for rhubarb but the rest will depend on the fruit.
