Def give over with the breadmaker, they do not get hot enough. Not for jam you want to keep...fair enough if you are just making one or two jars to use up promptly though.
Minimum water to get your fruit to melt into juicy pulp, the more you add to start with the more you will have to boil it once the sugar goes in, too much boiling means you will lose the freshness and clarity of flavour...you just get a sticky sweet jam that could be anything
You do need to add more water if you are making jelly though as you want a good stiff boil to get all the flavour and maximum amount of juice once it had drained through the jelly bag.
Do not add the sugar until the fruit is properly cooked, blackcurrants or anything with a heavyish skin will be like little boiled plasticky bits if you add the sugar too soon
If you have a pressure cooker prep the fruit in that first, it's ideal for the pre sugar stage.
Try and use as wide a pan as possible once the sugar is added, then you are evaporating water to get the temperature up to setting point which will happen faster in a wide pan.
Strawberries and rhubarb are buggers to set so maybe use jam sugar for those as it has extra pectin, but pretty much all other fruit will set well with normal granulated provided you haven't drowned it with water to start
In fact if you slice strawbs or rhubarb and put them overnight in a large bowl with an equal quantity of sugar and juice of a large lemon loads of liquid will come out of the fruit, no water will be required and a decent set is easy to get.
General principle is a pound of sugar to a pound of fruit, or if you are making a jelly it is a pound of sugar to a pint of juice.
I finally made some rosehip & apple jelly last week from last years rosehips that I put in the freezer, I am going to make rosehip tea with it when people are going down with colds. It's delicious on toast!
AND I am going to make some blackcurrant jelly too!
