Makin' Cheese in the Kitchen

Got a call from some friends that are building a dairy and creamery about 15 miles away. They had 10 gallons of goat milk that they couldn't use and were offering it to me. It thought about it for three seconds. Long enough to take inventory of our spare fridge. Do I have room for ten gallons of milk? You bet! Woo hoo! I jumped on the chance to grab some milk and make cheese.

I had to get my cultures, too. Luckily, there is a place on the way that sells cheese cultures as well as raw milk, eggs, and chicken. Kookoolan Farms is a great resource. They built their own chicken processing plant so that they could ensure that their chickens were treated humanely from hatching to slaughter. They are big cheerleaders for the consumption of raw milk. To make it easy, they provide the cheesemaking supplies to encourage folks to make cheese at home. Nice folks! I also mail ordered other cultures from the New England Cheesemaking Supply Company. I also like to stock up on stuff from Glengarry Cheesemaking from Canada.

Jim and I drove to Scott and Summer's place. In the fridge was the milk that they had promised. Two gallon milk cans and a bunch of half gallon jars filled with the goat's efforts. They milk 16 Nigerian Dwarf goats. I've never worked with the milk from this type of goat so this will be good experience for me. The goats are much smaller than the standard dairy breeds, about a third of the size. The give less milk but the milk is much richer. It is higher in butterfat as well as in yield (more solids held in suspension) as I soon found out.

We packed the milk in our coolers and rushed home to start the cheesemaking process. As we drove I was running over my recipes in my head. What to make? I want to make chevre so I can make a big batch of my chocolate chevre truffles. They freeze nicely so I can have them ready to give away for the holidays. I also want to make some raw milk, aged cheeses. Hmmmm.

We got home and transfered the milk into fridge in the garage. I pulled out my recipes and decided to go with the semi-firm aged goat cheese from Ticklemore. The first time I made it I dubbed it Sarahmore. This one will be different because I'm using fresh, raw milk from Nigerian Dwarf goats. Plus I don't have the same culture I used before. Kookoolan didn't have it, so I'm trying a different one and we'll see what happens.

Massive clean up of the kitchen took a while, so I didn't get the milk on the stove until 4:00. I use the double boiler method to heat three gallons of milk so I can ensure even heating and less chance of scorching. Gently heating means better cheese. Goat milk is very fragile. The more it is handled the more likely it will break down and add off flavors. Milk can get bruised! If it gets jostled around too much, the structure of the milk gets bruised and you get off flavors. Be nice to your milk and it will reward you in the end.

Slow heating means lots of time to get the molds cleaned, the sink scrubbed and everything sterilized. Gotta have a clean environment to make cheese. Lessens the chances of bad microorganisms entering the cheese. I want good food, not toxic sludge.

The milk heated to my target temperature and I added the culture. The ripening culture is freeze dried. When added to milk, the culture "wakes up" and begins to eat all of that tasty sugar a.k.a. lactose and makes the milk more acidic. A cheesemaker selects certain cultures for certain cheeses. If you want to make Monterey Jack, you want a culture that gives you a nice even texture without any eyes or holes. If you want to make something like an Havarti the cheesemaker will select a culture that produces a bit of gas and leaves small eyes in the cheese. Ecoli makes eyes that look weepy. Those weeping eyes must be crying because they can make you die. These are bacteria that have been selected by The Culture Houses of Europe because they produce consistent end results. These strains have been around for many years. It is only in the past century that these cultures have been isolated and replicated.

Some folks create their own starter with the naturally occurring strains in their milk and environment. Traditional English Farmstead Cheddar makers use their own starters to keep their cheddars tasting so good. Some have used the same mother culture for generations. If you ever eat sourdough bread from San Francisco you've experienced the same thing. A small amount of sourdough is held back after each batch to start the next day's bread. Remember kids, this stuff is alive!

Got another pot on the stove with two more gallons of milk. This other vessel of milk will be pasteurized so I can make chevre. The pasteurized milk will be cultured and left to sit overnight in a warm room. In the morning, the milk is transformed into a solid curd mass that looks like two gallons of tofu. When I think it is firm enough, I gently ladle the curd into a cheesecloth lined colander. The ends of the cheesecloth are tied together and I hang it up to drain for several hours. When the cheese is drained and as dry as I like it, I'll take it down, add salt and enjoy my fresh chevre.

Back to the other pot. The culture is acidifying the milk and the rennet is added to firm things up. More waiting. My molds are clean and sterilized. My knife is ready to cut the curd. I keep checking the texture, looking for a clean break. This is the point at which the curds hold their shape, and a small puddle of greenish whey is released from the cut surface. It is ready. I take my knife and I begin cutting the curds. I use a firm, assertive motion, trying to keep my cuts straight. I cut one direction and then rotate the pot and cut in the other direction, at a angle. The objective is to cut cubes or diamond shaped blocks of curd of a similar size. Large cubes = soft cheese, small cube = firm cheese. I finish cutting and wait again. This is the healing time. The cut surfaces are all releasing whey and contracting. Waiting allows the surfaces to literally heal so that when I begin to stir, they will maintain integrity as well as continue to release whey. We want the whey to go away, but at a controlled rate.

Time to stir. I stir slowly at the beginning. The curds are very fragile at this point. I want them to gently bump into each other, but not clump together. Stirring will go on and on. I pull of part of the whey and continue to stir. I add fresh water back in to wash the curds. Washing the curds removes some of the lactose, and will make a chewier and sweeter cheese when the cheese is ripe in a few months. You gotta put a lot of investment in the beginning and won't know the results for months. This is why keeping good records is critical. If the cheese turns out really well, I want to be able to repeat what I did. If something goes wrong, I want to know why.

I can see that the milk from Nigerian Dwarf goats doesn't need as much rennet as "regular" goat milk. This batch is a bit firmer than I would like. Better reduce the rennet for the next batch. The milk is thicker, almost like sheep's milk. Higher yield, too. Amazing stuff.

The curds have shrunk and are ready to go. Time to hoop! I've got my colanders ready to go, sitting on a cookie sheet over the sink. As fast as I can, I scoop all of the curds out and it the plastic forms. The curds are eager to mat. They're bonding to each other. They liquid that held them in suspension has now been removed and all they want to do is bind together. Putting them into a form like a colander or a traditional cheese mold helps give them a shape but also controls how quickly moisture is lost. In my case it seems to be losing moisture pretty fast. If I use a different form with different perforations, I'll get a different cheese because the moisture loss will change. Every little variable will make a big difference in the end result. This is one of my countless reasons cheesemaking fascinates me.

As soon as my colanders are filled, I flip them. The newly formed cheese needs to drain evenly, so flipping is essential. What was once in the bottom side of the cheese is now the top. A few minutes later I flip the cheese again. This process will be repeated over the course of a few hours. In the morning I'll flip them again and then I'll turn the cheeses ever day until they're ripe.

In order to free up my kitchen, I turned our laundry room into our curing room. The cheeses are set on racks over a clean and sanitized sink to drain and dry. The light is kept on so the room stays warm. This will encourage draining, too. My chevre bags are draining into the sink as well. I like this set up.

I repeated the process two days later, but this time all of my milk was pasteurized. We'll see how this will affect the aged cheeses. I don't know.

Now the wait. I made cheese on October 31st and November 2nd. They might be ready in January. I'm thinking February will be a better bet. The first batch of cheese is looking good, but a bit dry. Hmmmm. The second batch looks amazing. Funny, the better looking batch is made with pasteurized milk. We'll see what happens in a couple of months.

This cheese needs a name.

For a name, how 'bout Snowy White? (giving credit to the dwarfs while not annoying the Disney machine...) :o) Cynthia, who's being not-so-anonymously anonymous.

we will move to mexico & make cheese on our new farm.
so i am looking forward to seeing your new set up , & what you think a good cheese making room [creamery?] is?
ok where did you get thoes wonderful orange colanders the cheese is in ? i would like to get some, love the shape.
please post more often you are the best
grace in texas

Thanks Grace. I appreciate your kind words. I wish I knew what a good cheesemaking room looks like. From my observations, the best ones have lots of room. Good, positive air circulation, and the cheesemaker has easy access to all of the equipment. But even in cramped conditions, great cheese can be produced.
Where did I get the orange baskets? Those colanders or strainers came from an Asian restaurant supply store. In San Francisco you can find them at most places that sell kitchenware. They're cheap plastic and come in a wide range of sizes. They cost less than $1.00. I love the shape of the cheese, too! Several cheesemakers in England use colanders like these as their forms. I used them at Ticklemore. Good luck with your own efforts!
