They, in my experience, are really not that hard to make. The best price on camembert molds is from artisangeek.com and the owner is a member of this forum, that said I made my own molds and they work quite well for me. I am using P candidum-neige and like it, together with a morge made from the rind of a store bought brie. The neige is added to the make and the morge I spray on. This has worked quite well for me and I did it really just to get geo into the party. The opinions of other members is probably slanted towards geo 15 and PC-ABL. I see from another of your makes that you have ARN. The ARN and a P candidum would certainly be another option and one I want to try, Yoev (iratherfly), the owner of artisangeek likes it, and FRANCOIS another member here feels it is a bit yeasty to his tastes so it probably comes down to personal taste. Ozziecheese seems to be the go to guy for this type of cheese on this board so reading some of his posts is probably a good idea, although I haven't had good luck adding ultra-pasturized cream to mine and it's the only cream I can easily find. My cams without added cream have been wonderful so the cream isn't required by any means. I found the video on making camembert from promisedland farm on YouTube really helpful for my first make.

Basically smash op a bit of the rind with a sterilized fork in water to which you have added a small amount of salt and sugar and let it incubate for 16 hours in the fridge before use, it can be stored for a while, I think I have done 2 weeks, in the fridge. Spray on the cheese after the salt rub has had a chance to soak into the cheese (a few hours). Hope this was helpful, have fun.

BTW- I have found that the 4 for 2 dollar green topped food containers from walmart make great little minicaves for these things with the addition of a mat cut to fit the container, I use the plastic embroidery mesh. I don't seal the lids on them and they get turned daily until they go into the fridge, every other day after that. The containers and mesh get sanitized by a 30-60 second dip in almost boiling water.
