I am by no means a cheesemonger. Before we talked about writing this post, I'd only ever made ricotta. So, being thorough, I decided to make mozzarella enough times to feel comfortable sharing a method. I've been practicing in the FOOD52 kitchen, and in my own kitchen, for months (I like to be really thorough). For a while I thought I could make it happen without rennet, but I tested my theory and know better now. You need rennet. You also need citric acid powder. Luckily, those things are easy to locate. If you can find non-homogenized milk, I suggest you use that -- and please, stick to whole milk. The rest is really easy and fun, and if I can do it, anyone can. 

I'm showing you how I've successfully made mozzarella but if you have any tips, or favorite sources for supplies, I hope you'll share them in the comments section. 


First you have to make the curd. Start by dissolving rennet (on the left) and citric acid (on the right) in water. I prefer the rennet tablets over the liquid rennet. You can order these ingredients from Dairy Connection or The Cheesemaker. We also found this kit which has enough supplies to make four batches of cheese.

You can sometimes buy mozzarella curd from a local cheese shop, but making it from scratch is so satisfying. And it really doesn't take very long, so why not? 


Pour your milk into a pot and heat it to 85 degrees F over a medium-low flame, then add the citric acid solution. Using a slotted spoon, give the milk a gentle stir. Keep an eye on the temperature. 


Let the milk heat up to 100 degrees F and add the rennet mixture. Very gently stir the milk -- you'll start to see curds, just lift them up and down a few times and make sure nothing is sticking to the bottom of the pot. Don't over-stir or move your spoon vigorously.  


When the milk reaches 105 degrees F, turn off the heat and cover the pot. Let it sit for 10 minutes. The curds will have come together into a solid-looking mass, the whey will have a yellow tint -- just like the photo on the right. 


Place a colander on top of a bowl. Use a slotted spoon to lift the curds and place them into the colander. Let the whey drain off. 


Lift the colander to keep draining the whey. Using your hands, very gently (that's the key word when dealing with curds) press the whey out of the curds. 


When your curds are drained, break them up into evenly sized pieces. 


You need hot water for the next step -- as hot as your hands can handle. I've found that 180 degrees F is a good temperature for this step (but that's me, go your own way if that's too hot). I like to bring it to a boil and let it cool -- use your thermometer here and be careful when you're testing the water with your hands. Wearing food-safe gloves can help protect your hands from the heat if you're sensitive.

And don't forget to salt your water here, this is when your cheese gets flavor. You can buy cheese salt, but any non-iodized coarse salt will do. Gently drop curds into the water. 


Using a large spoon, lift the curds to see if they're ready for kneading. They're ready when they are melty-looking, like in the photo on the right. 


Now's the fun part: stretch and knead! 


And stretch and knead. If the cheese starts to get cold and stiff, dunk it back into the hot water. Keep doing this until the cheese starts to feel smooth -- you don't want your mozzarella to have a rough, flaky exterior. This can take anywhere from 5-20 minutes. 


Then form the cheese into a ball, or any other shape you might want. 


There you have it. 


Garnish as you like, and enjoy. 


Makes 1 large or 2 small mozzarella balls

1/4 rennet enzyme tablet
1/4 cup cold filtered water (to mix with the rennet)
1 1/2 teaspoon citric acid
1 cup cold filtered water (to mix with the citric acid)
1 gallon whole milk (non-homogenized is best)
Salt to taste

How much salt do you actually put in the water?
Annerieke W. March 29, 2015
We made this rather successfully, but the cheese is a bit plastic-y, not soft like mozzarella should be. I used raw sheep milk and it very quickly formed a 'block' of curd. The final product is definitely cheese, and probably will taste great molten but not so much to eat like this. Could it be we pressed too much whey out?
Annerieke W. April 13, 2015
update, the cheese went 'see through' rather quickly and didn't taste like mozarella at all... the milk had a really high fat content so that couldn't have been it, any ideas?
anna K. May 19, 2014
My curds are the texture of set yogurt - too soft to attempt to strain. Any way I can save this batch?
Thanks! Anna
Nina P. August 4, 2012
Thank you so much for the mozzarella recipe...worked first time but with a little help from the microwave....Still I'm happy...

I have made Mozzarella only once. While my mother thought it was great, my father thought it was a little milky tasting. Is there a specific known cause for this and a way to prevent it?
AntoniaJames April 22, 2012
I posted this on the mozza party update thread, so forgive the duplication for those of you who've already seen it. This is just a quick report/advisory for people who have yet to begin your mozza making. The editors are absolutely right about making the liquid that you use for stretching as hot as possible. It makes such a difference. We made three different batches. The last one, with really hot whey -- we used that instead of water, on hardlikearmour's suggestion -- turned out best, at least with respect to how easy it was to stretch the cheese. This may sound crazy, but I spent three hours yesterday making cheese -- getting whey everywhere, and I mean, everywhere -- and I want to make some more today!! ;o)

I am totally trying this at home tomorrow!!! I have tried before with horrible luck but I am always willing to give it another go. Wish me luck...

Kristen, this tutorial is really helpful and simple to understand. Thanks!
Kristen M. April 18, 2012
I agree! This was actually all Kristy Mucci's work (our Associate Editor) from the research and testing to photo styling to writing -- we're all in awe of how beautifully it all came out.
PistachioDoughnut April 22, 2012
oops! I meant Kristy..I very good at shuffling names. Sorry! Kristy.

I tried to make mozzarella following your method and the method in the Idiot's guide to cheese making. I didn't manage to obtain workable curds with your method, alas. Each time I tried to soak them in warm water, they melted completely all away. The alternative method of using the microwave did work, but the results were subpar. I talked about my problems here, if you are interested:
hardlikearmour April 16, 2012
I'm saddened by your lack of success. I implore you try again. I've successfully made mozzarella using the instructions from urbancheesecraft. They are similar to the food52 instructions, but not exactly the same. The water bath method does produce a superior result IMO - though I used the whey rather than water. I also added the salt with the kneading rather than in the water, which may make a difference. I found that thin black neoprene gloves did a great job of insulating my hands from the hot curd for stretching. If you try again, please report back! Mozzarella instructions (quite detailed, and includes a link to a photo album of the process):
tuscanfoodie April 16, 2012
Thanks! I plan on trying again before the potluck party takes place. I will let you know!
PistachioDoughnut April 18, 2012
I found a site from where I ordered my Mozzarella Making kit really useful, it is the from the and in a video on youtube by cgicitizen , similar method of making mozzarella which is similar to some extent to Kristen but not exactly same. But, your mozzarella on left looks good.
AntoniaJames April 15, 2012
Kristen, why do you prefer the tablets? Did you try with the liquid? Just wondering what the difference is, if any. Thanks so much. ;o)
MrsStorm918 April 4, 2012
Hey there, great tutorial! I just wanted to add that Lipase powder adds a lot of flavor to mozzarella cheese. My husband and I made a batch (different version) a few weeks ago and got to add the lipase to it. OMGosh it was delicious! We noticed that it was even better after it set for about 5 days, the flavor was amazing!! Definitely not something you can buy at the grocery store.
Patty H. April 3, 2012
Thank you for this very clear tutorial. We made cheese for my son's 2nd grade science fair (Understanding Chemical Reactions). We looked everywhere on line and could not find anything as clear and easy to follow as your instructions here. Thank you!

Can I use Junket instead of rennet tablets?
Author Comment
Kristy M. April 3, 2012
I haven't tried that. Since Junket is specified as being for custard and ice cream, I'd play it safe and order the rennet tablets. The kit only comes with 1 tablet, so maybe that is a good place to start.
hardlikearmour April 3, 2012
There is a recipe for mozzarella using Junket rennet in the book Artisan Cheese Making at Home.
phoebe's P. April 22, 2012
i think junket is the brand name of the rennet tablet manufacturer. I bought the junket brand and in the box with the rennet tablets was a recipe book which included all types of cheese (mozz included), ice cream and custard

Ok. I'm dying really bad. I need test it right now. The cheese ball seems to be so luxury, hahahah
pourhouse April 2, 2012
Instead of forming into balls, you can tie the kneaded string into little knots. To marinate, toss with olive oil, very finely chopped parsley, very finely minced basil, and crushed red pepper. Delicious! Any ideas on how to make burrata with the fresh curds?
Nicole E. April 2, 2012
Burrata uses all the same steps but during the stretch process you mix half the mixture with heavy cream and salt then stretch the other half to wrap it around your creamy mixture. The technique takes practice but it's worth it! For the record, FARMcurious sells cheesemaking kits and teaches in-depth cheese classes in the SF area:

Are you trying to avoid chlorine when you specify 'filtered' water?
Author Comment
Kristy M. April 2, 2012
Yes. You don't want the water to add any funny flavors to your mozzarella.
Nicole E. April 3, 2012
Also, chlorine can reduce the effectiveness of your rennet.
Renée (. April 1, 2012
I just had a Twitter conversation about this, today! As soon as I can lay my hands on the vegetarian rennet (I already have citric acid) and hit the Whole Foods for the non-homogenized milk, I'm in!
Anna H. March 29, 2012
Does anyone know where to get rennet and citric acid in New York?
Author Comment
Kristy M. March 29, 2012
Hey Anna, Sur La Table sells those kits I linked to. Hope that helps!

I have seen Rikki the Cheesemaking Queen's mozzarella and ricotta making kit at Murray's as well as a few other places (Brooklyn Victory Garden). I have it and it comes with the thermometer, cheesecloth and a little recipe booklet as well (with things to do with the leftover whey for instance).
GoodFoodie April 1, 2012
What do you do with the leftover whey?
lackerman April 1, 2012
I just made ricotta cheese this week and was asking myself the same question as I had one qt of whey in my frig. I ended up finding a whole list of food items you can sub it for.
Today I am using it in place of the water in a bread recipe.
Renée (. April 2, 2012
Absolutely! When I make Indian paneer cheese, I always use the whey to bake bread instead of water or milk. It's a great protein addition.
La C. April 3, 2012
Feed left over whey to the pigs. No, seriously, this is what my local cheese maker does. Eventually, the pigs are turned into saucisse (salami).
Nicole E. April 3, 2012
There are lots of places to use your leftover whey (whether it's salted or not changes the use):
Use instead of water to cover your meat/veggies when making a homemade stock.
Use in smoothies
Use in place of water or milk in a bread recipe
Spray on plants that are subject to powdery mildew (the acidity discourages the mildew)
Pour on soil under acid-loving plants (be sure to strain out any mozz chunks)

Many more things to do too! I post lots of ideas on Happy cheese making!

Here is the full list of ideas for using up your whey:

How much citric acid to use? Did you use standard vitamin c tablets?
Author Comment
Kristy M. March 29, 2012
I used the citric acid powder you can get from any of the three sources I linked to. I never read about using vitamin C tablets, have you?
Panfusine March 29, 2012
Where can I find Microbial Rennet (the vegetarian version)?, Would be great if you could direct me to a link please!
Author Comment
Kristy M. March 29, 2012
Panfusine, Dairy Connection has vegetarian rennet -- I made sure to find sources with both options!
Panfusine March 29, 2012
Found the link from the cheese sites,! thanks!
