Liquid Pectin instead of lemon juice in jams

[Farmer_Gyles]

Does anyone know how much liquid pectin to use in jams?
We're making a bramble jelly - would normally use 3 tablespoons of lemon juice per half pint of liquid - we have 2.5 pints of liquid, to which we've added 2.5 pounds of sugar
But how much liquid pectin do we need??

No idea - I make my own - chop up whole crab apples or unripe eating or cooking apples, place in a saucepan with enough water to cover, and simmer gently until pulpy. Strain through muslin. To set a couple of pounds of fruit like strawberries I would generally use about ten ping pong ball size crab apples. When I make jelly , the chopped apples go in with the other fruit and half a pint of water and are all cooked and strained together.

That's probably no help at all, sorry.

If you've bought liquid pectin it should tell you on the bottle how much you need to use.

To ensure a good set I use agar agar when making jams and jellies, don't have to boil for so long.

If you use homemade pectin its about 90ml to 450g of fruit
