Making farmer's cheese question

[joesfolk]

I. tried to make farmers cheese with heavy cream. But it won't curdle for me. I brought it just to a boil added lemon juice and waited. There is a very slight curdle in it but not enough to make the cheese. So I added a little more lemon juice. Still not working. What should I do?
