I make ganache with 2 parts chocolate, 1 part heavy cream.

I screwed up last night (long story) and forgot to tare the weight on my scale once I put my bowl on it. So this morning I am realizing there is too much cream.

Can I add more melted chocolate now or should I start a whole new batch?

I would add more chocolate, if it doesn't seem to be mixing in well you could put it in the microwave for 15 seconds at a time to try to loosen everything up. HTH

Thanks. I did add in more chocolate and it worked fine.
