Hello Amo - here's the recipe you were after. Sorry about taking so long to get it down. I used ordinary apples (but growing wild) and it worked out just fine.
Elderberry and Apple Jelly
2lb (1kg) elderberries
1 1/4 pt (1L) water
1lb (450g) crab or sour apples
Juice of one lemon
Sugar - 1lb to every pint of juice, after straining)
Small knob of butter to reduce foaming whilst cooking
Wash elderberries and remove stalks. A fork is helpful in doing this. Wash the apples and prepare them by cutting up and removing any blemishes. Don't peel or core them. Put fruit and lemon juice into a pan with the water and simmer gently for about an hour, until soft. Strain overnight through a jelly bag. Measure the strained juice and add the sugar.
Stir until thoroughly dissolved and then bring to a full rolling boil for about 10 mins. Test for setting by placing a teaspoon of the juice on a cold plate, cool a little then push with finger. If it wrinkles strongly, then it is ready. Stir in the knob of butter to reduce foaming and skim if necessary. Pour into sterilised jars. Sorry, bet you knew the last few sentences - just copying the recipe verbatim.
