what does "PF of .75" mean?
Milk protein to fat ratio. Meaning Nubian milk is richer than other breeds, so you have to adjust the make a little to hit the right moisture targets. Typically, don't need to stir as much, and can use normal 3/8" -1/2" curds.
Am I supposed to measure an inoculation rate of 1.5% or do I just use "x" amount of teaspoons of the 1.5% Danisco RA?
Measure. In Danisco's world, this is 8-10 DCU per 1,000 liters, IIRC. Search the forum for "bulk equivalent". I have posted tables before.
that leads me to... under cultures do I choose one of the three options you listed or use both Danisco RA and FLAV?
You must have RA. FLAV is to add flavor, texture, and aroma. It gives you a bit more sharpness and savoryness.
and I couldn't find Danisco RA and FLAV at the dairy connection,
Call the,, or order from somewhere else.
I guess I don't know how to read the labels correctly. I have Danisco Choozit MM100 LYO 50 DCU.
You can use MM, the cheddar will be alright. Not amazing, but decent.
For 3-4 gal of milk how much culture do I use?
Easiest for you is likely teaspoon type measures, right? a Little less than 1 teaspoon, then.
ok, for rennet I have Marschall M 50 Coagulant tablets, can I just use 1/4 tablet as usual?
What is your time to flocculation with that amount? You must hit a time to floc of 10-12 mins.
should I add any lipase?
No.
I don't anything about checking moisture or changing the stir schedule. Can you recommend a source to teach me how to do this?
It's a hand-on, feeling, experienced-based kind of thing. You clump the curds into a ball and check if they are done or not. If you don't know, don't worry about it. Take notes during the make for how the curds felt, and then when you cut into the cheese to eat it, go back to compare how the moisture is based on how the curds felt.
When talking about pH you said "If using TA, you should be around .23" What does that mean?
If you are titrating and not using a pH, probe, the TA is .23.
I should drain it in cheese cloth and that fuses the curd back together and the pH of the whey has dropped to 6.05 but not below?
When the curds meld initially into the first loose slab, the pH should be below 6.05. I'm trying to give exact guidance because in cheddar, often you start draining the pH, and by the time you finish and pack the curd, the pH has dropped another .1-.2. So This is your quality control point so you can tweak the recipe.
Can I use pH strips, if "no" then, is there an inexpensive meter you can recommend? The one at dairy connection is $114. I'm thinking it may be better to buy it but good grief...
You can, if you can read them well. The thing about pH is that it is not an absolute. The best way to use pH is to understand what it really means, and to use the change is pH between steps as a way to make decisions. It's not just pH. It's pH, moisture, temperature, agitation, milk PF, etc.
How can I measure salt content of 1.8%? Can I just use, say, 2T of salt?
You measure the weight of the cheese. Then you figure out the amount. Then you figure out the anticipated loss. Say, you need 2.1% for a final salt content of 1.8%. So you add that, in 2-3 saltings with a rest period of 2-5 mins between saltings while you turn over the curd. In a vat, it all makes sense. One guy salts, another guy turns with a shovel/pitchfork. By the time you finish one salting, you go back and start the other because it takes 5 mins to finish.
Maybe you are familiar with it and its calculator.
Use as much pressure as sanely possible. You can use 60 PSI on cheddar if you want. 30-40 is common commercially. This is not an exact calculation. More of a "crank it up"
Should I increase pressure a few times and flip the cheese in the mold?
Yes, especially at first. Cloth will stick. Redress a few times.
Finally, really, the only "cave" I have is my basement. Will that be good enough to age cheese? It is cool and dampish but I dont know the exact temp or humidity.
I have no idea. Does it fit the parameters I specified? 45F and 85-90% RH? If not, you can use it, but aging will be different. Cheddar is best when done low and slow.
