Blue Cheese

This will be my first attempt at making a Blue Cheese. I've chosen a recipe from CheeseMaking.com called "Spanish Blue Cheese". This is intended to replicate a famous cheese I've never had called "
Picón Bejes-Tresviso".  There are a lot of steps involved including a few months of aging at high humidity so it is a pretty good investment in time to make them.  I really enjoy a blue cheese with salad but it is quite expensive - hoping I can find some success here and make some more of these.

The mold that gives blue cheese it's name requires oxygen to grow.  In order to get mold that spreads through the interior of the cheese it is necessary to have the curds come together in a way that leaves air pockets (which are later exposed to the outside by skewering the cheese).  To form the air pockets it is necessary to dry out the curds to a certain extent before adding them to the form.  You still want the curds to have a good amount of moisture as well so, apparently, there is a delicate balance to be achieved.  This being my first time making the recipe I tried not to stress too much about it - I believe I was likely fairly successful in drying the curds out and creating air gaps but will just have to wait a few months to see for sure.

Anyhow, I'll be aging the cheese in my temperature and humidity controlled cheese cave (converted dorm fridge) - the temperature in the basement is pretty good in the high 50s but the humidity is down in the 30% range which is too dry to make this cheese.

At the time of this posting I think I'm off to a pretty good start.  Excited to report on how it goes and hoping it increases my confidence to try some other more complicated cheeses

Recipe Details:

• 3 gal Pasteurized Cow Milk
• 1/8 tsp MA 4002 Mesophilic and Thermophilic Starter Culture
• 1/16 tsp Pencillium Roqueforti (PJ)
• 3/4 tsp Cacl
• 1/2 tsp Rennet mixed with 1/2 cup of spring water
• 3% weight of the cheese in Salt (I used Kosher Salt) - cheese was 1643 g so 49 g of salt

Process Notes:

• 12/23/23:
• Heated the milk in a 5 gal pot in a water bath to 80 F using my Sous Vide circulator

• Added the CaCl and Mesophilic and Thermophilic Starter Culture while the milk heated
• Reyhdrated the mold while the milk came to temperature.  Added this in once at 80 F and stirred to mix everything

• Let the milk sit at 80 F for 90 min to let the cultures start to do their work
• Added the rennet and stirred it in.  Let the milk coagulate for 90 more minutes
• Sliced the curd into a 1 inch grid on the virtical.  Let it sit for 5 min and then sliced on the horizontal
• Stirred the curds over the next 15 min and broke them up a bit

• Gradually transferred the curds to a colander and to a mat to drain in small batches.  I then added them to a separate pan to dry out a bit more before adding them to the form.  This ended up taking a couple hours since I didn't have a mat big enough to handle the amount of curd.  This is the tricky step I noted before and was a real pain.  I need a better approach for this next time.

• Added the curds to the form and let this settle in the basement over night in my utility sink above a pan full of hot water to help keep it warm

• 12/24/23 
• Measured out salt and added 1/3 of it to the top of the cheese
• Moved the cheese to my cheese cave at 88% humidity and 13-15 C

• Flipped the cheese a couple times but kept it in the form.
• 12/25/23 - Added salt to the other side and flipped a couple more times
• 12/26/23 - Salted the sides of the cheese and flipped
• 12/27/23 - Removed from the form and am flipping 1 time a day now.  Waiting to see signs of green mold forming now
• 1/1/24 - The cheese has started to form the blue/green mold.  I have poked holes about 2/3 of the wheel deep on the top and bottom of the cheese.  I'd been keeping the cheese in the high 50s F and at 88% humidity when the recipe recommends 52 F and 80% - I'm adjusting my controllers to this effect

• 1/13/24 - The blue mold has covered the whole cheese now.  I was a but concerned that the holes plugged up so I pierced the cheese again.  The cheese is getting a little slimy which the recipe warned of

• 1/21/24 - Lowered the temperature of the mini-fridge to 43 F and increased humidity to 90% for final aging - maybe a couple more months
• 1/26/24:
• The cheese is starting to develop some orange colored spots (which is expected for this type of cheese

• I've decided to proceed to wrapping the cheese (in parchment paper and foil) which is supposed to cause the blue mold to slow down and work on the internal part of the cheese to create a creamy texture and sweet flavor as it ages for several more months.  I still have it in the mini-fridge

• 4/5/24 - The blue cheese has been aging for a bit over 2 months now at about 5 C and in the high 90% humidity range.  I've got it in a ripening box which is doing a good job keeping the humidity high at this temperature (my attempts to keep the whole chamber in the 90% humidity range resulted in the humidifier running constantly).  I plan to give it another couple of months to ripen.  The cheese is looking about the same
