feta cheese

Some friends came round for a day of cheesemaking. Feta! We followed the recipe from Mary Karlin’s excellent Artisan Cheesemaking at Home, reprinted below with kind permission. Little by little I’m becoming accustomed to the basic steps in cheesemaking, and if you’re so inclined, I so encourage you to try it.

Cleaning and laying out tools. Raising the milk to temperature, adding the starter, whisking it up and down. Covering for a certain time to ripen until whey and curds separate and show a clean break. Cutting the curds to a certain size, depending on how much whey to release.

Stirring them, letting them rest. Lining a colander with damp butter muslin, filling it with curds, tying it up and hanging it to drain. These natural waiting times are just right for sitting down with the children to knit, preparing a meal, or going outside to play.

We were excited to go a step further than other cheeses we’ve tried at home, and move the sack to a mold, and flip it after an hour. Though a press isn’t required, the cheese acquires a very pleasing shape. A square mould would’ve been traditional, but do use what you have. There’s something wonderful that happens when you see it – a cheese! This familiar object! The children were as amazed as I.

They helped with it all. I love for them to know how this is done, that this is possible, even easy. This comfort with old skills is often absent from our lives, and I feel good when it is restored.

How gratifying it is to submerge the cheese in a light cold brine. Three weeks wait makes tasting the cheese all the more exciting. Ah. This feta is very pleasing, and we can’t help peeking into the fridge with pleasure, to gaze on our homemade cheese. We’ll make it again come summer with milk from the goats on the farm, to pair with our homegrown tomatoes, basil, peppers.

Here’s the recipe:

Makes: 1 pound
Milk: Pasteurised or raw goat’s milk, or alternatively cow’s or sheep’s milk
Start to Finish: 4 to 26 days: 2 ½ hours to make the cheese; 4 hours to drain; 5 days to cure dry salted; 21 days to cure in brine (optional)

1 gallon goat’s milk
¼ teaspoon mild lipase powder diluted in ¼ cup cool non-cholorinated water 20 minutes before using (optional)
¼ teaspoon Aroma B powdered mesophilic starter culture
¼ teaspoon liquid calcium carbonate diluted in ¼ cup cool non-chlorinated water (omit of using raw milk)
½ teaspoon liquid rennet diluted in ¼ cup cool non-chlorinated water
2 to 4 tablespoons flake sea salt or kosher salt
Kosher salt or cheese salt for brining (optional)

1.Read through the recipe and review any terms and techniques you aren’t familiar with. Assemble your equipment, supplies and ingredients, including a dairy or kitchen thermometer; clean and sterilize your equipment as needed and lay it out on clean kitchen towels.

2.In a nonreactive, heavy 6-quart stockpot, combine the milk and the diluted lipase, if using, gently whisking the lipase into the milk using an up-and-down motion for 20 strokes. Place over low heat and slowly heat the milk to 86F. This should take 18 to 20 minutes. Turn off the heat.

3.When the milk is at temperature, sprinkle the starter over the milk and let rehydrate for 2 minutes. Whisk the starter into the milk to incorporate, using an up-and-sown motion for 20 strokes. Cover and, maintaining the temperature at 86F, let the milk ripen for 2 hour. (Refer to page 17 for tips on maintaining curds or milk at a steady temperature for a period of time.)

4.Add the diluted calcium chloride to the ripened milk and gently stir with a whisk using and up-and-down motion for 1 minute. Add the diluted rennet and incorporated in the same way Cover and maintain at 86F for 1 hour, or until the curds form a solid mass with light yellow whey floating on top and show a clean break (see page 18). If there is no clean break after 1 hour, test again in 15 minutes.

5.Cut the curds into ½-inch pieces (see page 19) Still maintaining a temperature of 86F, allow them to sit undisturbed for 10 minutes. Using a rubber spatula, gently stir the curds for 20 minutes to release more whey and keep the curds from matting. The curds will look more pillow-like at the end of this process. If you want a firmer curd, raise the temperature to 90F for this step. let the curds rest for 5 minutes, undisturbed, still at temperature. The curds will settle to the bottom of the pot.

6.Line a colander with clean damp cheesecloth or butter muslin and, using a slotted spoon, transfer the curds to the colander. Tie the corners of the cloth together to create a draining sack (see page 20) then let drain for 2 hours, or until the whey has stopped dripping. The curds should form a solid ass and feel firm; if not, let them dry for another hour. If you desire a more uniform shape, after ½ hour of draining in the colander, transfer the sack to a square cheese mold or plastic mesh tomato basket set over a draining rack. Line the mold with the sack curds, press the cheese out into the corners of the mold and finish draining. Remove the cheese from the cloth and flip it over every hour in this draining process to help even out the texture and firm up the cheese.

7.When it is drained, transfer the cheese to a bowl. Cut it into 1-inch-thick slices and then into 1-inch cubes. Sprinkle the chunks with flake sea salt, making sure all the surface are covered. Loosely cover the bowl with a lid or plastic wrap and allow to age in the salt for 5 days in the refrigerator. Check daily and pour off and expelled whey. The feta can be used at this point or stored in a brine. Or for a saltier flavor, dry salt and refrigerate for 24 to 36 hours then transfer to alight brine (see page 24) to finish for another 21 days. If the finished cheese is too salty for your taste, soak the cheese in nonchlorinated water for 1 hour, then let drain before using. Feta can be stored for a few months in a brine.

Thanks ever so much, Mary. We adore your books.


For a while now I’ve been perfecting the art of making mozzarella. It’s a fabulous party trick, that stretchy stuff, so I often make it with friends visiting the cottage. My dear Catherine, an artist and a fine brewer (with whom I have exciting brewery plans…) made mozzarella with me this weekend and we took some pictures of the happy event. Here’s an illustrated guide, based on a brilliant recipe I’ve had great success with.

Gather the ingredients: 8 pints of fresh whole milk (we use demeter-approved organic raw whole milk from our beloved local farm), a bit of rennet, citric acid, and sea salt.

Gather the tools, sterilised, and keep them close to hand; make sure your sink is clean and has a good stopper. A sieve or a colander, a slotted spoon, a 2 gallon pot, measuring cups and spoons, a wooden spoon, a large heatproof bowl or pot, a long sharp knife and a cooking thermometer. Also, rubber gloves if you’re a sensitive creature and for children who want to pull the mozzarella. Ready?

Measure a quarter teaspoon rennet (or a quarter tablet) into a quarter cup cool water, stir it well and set it aside.

Measure 1.5 teaspoons of citric acid into half a cup cool water, and stir til dissolved.

Place the large pot into the sink, and tip the citric acid solution into the pot.

Pour in all the milk and immediately stir;

Stir it very well. Now the milk is acidified and we’re on our way.

Stand the thermometer in the milk, and fill the sink, around the pot (no! not in it!) with hot water, just from the tap should do. Keep watching the thermometer, it need only go to 90 F/32 C, which isn’t very hot at all. Much like making cream cheese. I generally fill the sink about two thirds of the way up the pot. Reached the right temperature?

Now pour in the rennet solution, and stir up and down for 30 seconds. Excellent.

Let the mixture stand for about five minutes. While you’re waiting, get a full kettle of water to the boil, we’re going to need it soon.

Press the top with a flat hand. You should feel soft curds, and along the edges the chartreuse whey should show. If in doubt, give it a couple more minutes. (This didn’t happen for us the first time, as the milk we were using was over-pasteurised, no luck.)

Where’s your knife? Cut the curds right to the bottom, into squares of about 1 inch.

Leave it to rest another two or three minutes. Meanwhile, take your water off the boil and let it sit for a bit.

Lay a sieve or colander (I begin with the sieve, as my colander just doesn’t let much whey out) over a large bowl, next to the pot of curds and whey. Take the slotted spoon and begin to gently lift the curds into the colander to drain. Exciting? I shift curds to the colander, now over the pot, when the sieve gets too full, and tip all the whey around it. The colander will be sitting in whey to keeps the curds warm.

A few pinches of sea salt go in, and get worked through the curds. The more your work them, the dryer the final mozzarella will become.

Pour most of the kettle-ful of water into a heatproof bowl or pot (I use that same bowl that caught the whey) and adjust the temperature to about 175 F/79.5C. Reserve some water in case you need it.

Use the slotted spoon to lift the curds into the hot water, working in two or three parts if you like.

Move the curds around to help them melt into a ball.

homemade mozzarella © elisa rathje 2012

Now! Lift it with the slotted spoon (put on your gloves if you need to!) and begin to pull and fold the mozzarella! If the cheese breaks as you pull it, melt it up again in the bowl, adding hot water as needed. I love this part.

Oh! The mozzarella stretched so far, my arms weren’t long enough! It always makes me laugh. Pull it, fold it, immerse it, pull it, til a sheen like good taffy appears.

Then fold it up, done! I keep our mozzarella submerged it in salted whey, chilling in the fridge, until I need it for lasagna or pizza. Soon we’ll eat it sliced with basil and tomato on fresh bread. Heaven! Do let me know if you make your own.

culturing yogurt

For years I’ve cultured yogurt, trying a variety of recipes and methods, in pursuit of rich, thick, Greek style yogurt. I’ve cultured yogurt in a machine, by the light of an oven, near a radiator, by a wood stove. I’ve tried endless combinations of starters. I’m ecstatic to finally have a method that achieved the thickest, the best, the most gorgeous yogurt.

I took out a pot of yogurt and a couple of pints of raw whole milk to come to room temperature on the counter, and then heated the milk slowly to 110 F. This is very quick, don’t go anywhere. While it was heating I filled a large jar with very hot water, and let it stand, closed. Three or four tablespoons of yogurt went into a cup, and a bit of warm milk ladled in and mixed. Then I poured out the hot water, poured in the milk, stirred in the cup of thinned, warmed yogurt, shut the jar, wrapped it in a towel, and put it somewhere warm. I reckoned that if the sourdough sponge liked the airing cupboard, the yogurt might like it too, so that’s where it spent the night. In the morning it was thick enough to wobble pleasantly. But not thick enough.


I happen to have a bit of cheesecloth sewn into a bag, so I used it, but you could use layers of cheesecloth in a colander just as well. I hung it up for a couple of hours to allow some of the whey to drain off into a jar.


When there was roughly half of the amount of liquid drained off the in the form of lovely chartreuse whey, I put the yogurt into its own jar. From two pints of milk and a few tablespoons of yogurt, I got just over a pint of whey and just under a pint of yogurt.


Gorgeous, thickest, best yogurt. It received the children’s highest rating (something involving many fingers and lots of waving) and disappeared immediately. The whey will be used in place of water in our next sourdough, or to soak oats overnight for porridge. I think we’d better get some milk to start it again. Oh yes, and next time save a ladleful to start the next batch.
