First, what do you call “medium pressure?” Do you use the same weight for all the pressing stages, or increase gradually?
Good question! This stumped me too until I flicked through the book I got the recipe from (200 Easy Cheeses) and found where she explains that ‘light pressure’ is 5 to 10 psi, ‘medium pressure’ is 10 to 20 psi and ‘firm pressure’ is 20 to 45 psi or higher. She goes on to explain that for a tomme mould with a cheese requiring medium pressure, a 5-gal pail of water (=40lb/20k) would do the trick. For my little 4l, 11cm cheese, my notes tell me that I pressed at 5k for 30 mins, turn over, 5k for 2 hrs, turn over then 11k overnight. I think this was more a result of how many dumbbells I could balance without causing an avalanche, rather than any careful calculation of psi. Gotta get me a proper press. After the first 30 mins there was quite a bit of whey on top of the cheese, which is why I removed it from the mould and turned it over. Also gotta get me a proper mould with holes in.
Second, I’m unfamiliar with “aroma mesophilic culture.” Can you explain what that is?
Again, you and me both! At the time I had no cultures at all, and used plain yoghurt. I mailed the New England Cheesemaking Supply people for advice when ordering cultures, and their Jim Wallace told me that ‘aroma mesophillic culture’ is the same as an ordinary meso culture, but it also produces ‘aromatics’. The ones they sell at NECS (MM100, Flora Danica) come only in larger pack sizes and, he said, it would be perfectly OK to use only ordinary meso culture.
I know Caerphilly is supposed to be a very salty cheese. Do you suppose that reducing the brining time would alter the flavor as well as reducing the salt content? I guess it wouldn’t be a genuine Caerphilly though, now would it?
You realise you’re asking a total beginner??? I have no idea! It was only after I’d brined my tiny cheese for 20 hours that I realised that being only a quarter of the original recipe it probably didn’t need that long and should have been scaled down like the rest of the recipe. Or maybe brining is different from adding the salt directly to the curds, in that once the cheese has gained a balance it doesn’t take in any more salt from the brine? I really have no idea and still have a long wait before I know how my little Caerphilly will turn out. I imagine it will be a long, long, long time before I produce anything resembling a genuine, recognisable any kind of cheese! For the time being, I’m happy with any palatable result.
I’m finding that cheesemaking is a bit like gardening - it makes you believe in, and look forward to, the future.
