Dear news group

I got a question about using gelantine.

When I read the recipe of making a quark gateau, they say "take 6 leafs of
gelantine". When I check the gelantine package, they say "use 6 leafs with
0.5 liter of cold water, soak them for 5-7 min and squezze them slighty at
the end".

So the question is, which part do I have to take at the end ?

1) Do I need to pour the 0.5 liter water with the gelantine extract into the
quark or
2) should I heat the gliber remains of the gelantine and use this part ?

Thanks and bye,
Oliver
