Esrom Cheese Making Recipe Instructions

Acidify & Heat Milk

Begin by heating the milk to 76°F. I know some of you will be surprised at this lower temperature, however some of the culture (one of the aroma producers) has a lower optimum working temperature. You can best heat the milk by placing the milk pot into another pot or sink of very warm water.

If you do this in a pot on the stove make sure you heat the milk slowly and stir it well as it heats

Once the milk is at 76°F the culture can be added.

To prevent the powder from caking and sinking in clumps, sprinkle the powder over the surface of the milk and then allow about 2 minutes for the powder to re-hydrate before stirring it in.

The milk now needs to be kept at 76°F for about 60 minutes (best for the aromatics).

Then raise the temperature to 88°F and hold for another 30 minutes. This will be optimum for the acidifying bacteria. Total time for the ripening phase is 90 minutes.

Hold the milk with culture quiet to allow the culture to begin doing its work. It will be very slow initially but will soon kick into its more rapid rate of converting lactose to lactic acid.

During this ripening time is a good point to make sure you have sanitized the mold and cloth for the final curd pressing if you have not done it already.

Coagulate with Rennet

Then add 3.4 ml or slightly less than 3/4tsp of single strength liquid rennet.

The milk now needs to sit quiet for 30 minutes while the culture works and the rennet coagulates the curd. The thermal mass of this milk should keep it warm during this period. It is OK if the temp drops a few degrees during this time.

You should notice the milk beginning to thicken (flocculation point) at about 12 -15 minutes but do allow it to sit quiet the full 30 minutes to form a firm curd. If the curd is not firm at this point, then allow it to rest a bit longer until it tests for the firm curd (splits cleanly).

Cut Curds & Release Whey

Once the curd has formed well it its time to cut it to about 3/8"pieces (about chickpea in size).

Do this by cross cutting vertically with a long knife ending with a good checkerboard pattern and then using a flat ladle or spoon make the horizontal cuts.

Cut slowly and evenly to avoid excess breakage. When done allow the cut curds to sit quiet for about 5 minutes to allow the curds to firm.

Then stir gently for another 5 minutes to make sure the curds are well separated. Gentle is the key here. A simple bottom to top motion is good.

Wash & Cook the Curds

You can now begin drying out the curds. This will be done by increasing the heat slowly to 95°F.

Since the character of this cheese is on the sweet side you will do this by using the Washed Curd Process:

1. Remove about 30% of the milk volume in whey. This will be removing some of the sugar supply for the bacteria and cause them to produce less acid.
2. Then add back enough water (Non-chlorinated) at ~120°F to raise the temperature to 95°F over the next 15 minutes to slowly heat the milk. This will heat the curds to the higher end of their working range, thus slowing down the acid production. It will also increase the flow of whey out of the curd ... drying them further.
3. Continue to stir gently for another 15-30 minutes until the curds show the proper dryness. This will become apparent as the curd mass becomes less 'spongy' in the hand and the curds show a tendency to separate easily when squeezed..

The final curds should be cooked well through and should be examined to make sure that enough moisture has been removed. A broken curd should be firm throughout and the curds should have a moderate resistance when pressed between the fingers.

Remove Whey & From the Curds

At this point the curds should test dry enough. Stop the stirring and allow them to sink to the bottom of the pot. The next step is to remove the whey from the top of the curds, leaving about 1" of whey above the curds. Then give the curds a good stir to make sure they are well separated. This little bit of whey will help the curds float into a nice tight formation in the mold.

Line the mold with the cloth for draining and transfer the curds to the form. Use a firm hand pressure to consolidate as you transfer.

At this point the process has only taken about 4.5-5 hours from adding culture but the culture has not fully done its work. It is still a very sweet curd/cheese because you have slowed the bacteria down with the whey removal and short stirring time so it now needs the time while in press to continue the acid development.

The curd should now be at its proper moisture level and ready to be transferred to the mold. The small amount of whey transferred with the curds will help the curds flow into place as you fill the mold. As the whey drains the curds will move into a more consolidated position.

As you transfer the curds to the mold stir the curds with your hand to assist the whey draining and help the curds form into a tight mass. A little hand pressure can also help in this. Once the whey has drained and the curd mass is nice and compact, fold the cloth over the top neatly and you are ready to place the follower on top and begin to press

Pressing

For pressing we should begin very light and slowly increase the press weight to a moderate level.

Pressing Four Gallon Batch:

• 15 minutes at 8 lbs.
• 30 minutes at 25 lbs.
• 60 minutes at 50 lbs
• 5 hours at 75 lbs.

Pressing Two Gallon Batch:

• 30 minutes at 8 lbs.
• 30 minutes at 25 lbs.
• 60 minutes at 50 lbs

The rate of whey running off begins as a matter of drops or a very thin stream of whey being released. This is a good rate of whey removal during pressing and will slow even more as the residual free moisture is released. The form should show tears of whey weeping from the form very slowly. When this stops you can increase the weight slightly. The cheese should be removed from the press, unwrapped, turned, rewrapped, and put back to the press at the above intervals to assure an even consolidation.

At each turn you will notice the cheese has formed a smoother surface and rests lower in the mold.

Note the nice tight surface resulting from a proper pressing. This will make it a lot easier to finish the washing of the cheese.

Salting

You will need a saturated brine prepared for salting this cheese, find all of the details you need on brining here.

A simple brine formula is:

• 1 gallon of water
• 2.25 lbs of salt
• 1 Tbs calcium chloride
• 1 tsp white vinegar
• Bring the brine and cheese to 50-55°F before using.

The cheese now weighs about 5.5-5.75 lbs. and needs to be set in the brine for about 11-12 hours (about 2 hrs per pound).

The cheese will float above the brine surface so sprinkle another teaspoon or 2 of salt on the top surface of the cheese.

Flip the cheese and resalt the surface about half way through the brine period.

At the end of the brine bath, wipe the surface and allow the cheese to surface dry for a day or two before moving to the aging space. The surface will darken somewhat during this time.

Aging

The aging of this cheese follows the process for a washed rind cheese but this will be developed only for a short time and then washed away. This will give the cheese a warm nutty flavor. You may see this referred to as a washed rind or smear ripened cheese depending on the surface moisture control of the cheese.

The cheese should be placed into your aging space at 52-56°F and 87-92% moisture. Rest the cheese on a mat that allows a little air flow underneath. To maintain the higher moisture use a covered plastic container as shown above. The higher moisture of the cheese should maintain the proper moisture level.

For the washed rind, your objective is a cheese surface that is neither wet nor dry. It should feel a bit dampish and perhaps even a little 'tacky'. Swampy is not what we want here. Make sure you turn the cheese daily

At about day 2-4 you should notice a definite slippery or greasy nature to your rind. This is a complex of natural yeast populating the surface and you should notice a definite yeasty or fruity smell to it.

Then at about day 5-6 days from making, you should notice a slight dusting of white mold beginning to form (you may really need to look at the surface to see it). This is the geotrichum community developing shown at the right here.

Washing

When you see the white mold first forming, make up your wash from 1 cup of boiled non-chlorinated water and a tablespoon of salt. This should give you about 6% salt in your washing brine. You may also add a pinch of b.linens and geotrichum for the rind growth just as added insurance. I did have you add it to the milk originally as well.

Within a few more days you may see the first of other unwanted molds. This is where the salt wash comes in for control.

Steps for wasing after the first signs of mold growth:

1. To remove unwanted mold, dampen a clean sanitized cloth with this brine and wipe ONLY the top surface and sides. This will spread, the growing molds around, moisten the cheese surface with your light brine to provide the salt which will discourage unwanted molds (blues, mucor, etc).
2. Return the cheese to the aging space keeping the washed side up. If the surface seems a bit dry improve the moisture in your aging space or if too dry reduce it .
3. On the next day turn the cheese and repeat the same above with the new unwashed surface.
4. Allow the cheese to rest again with only daily turnings.
5. You should again see the white mold coming again in 2-3 days.
6. Repeat steps 1-4 again when you see this.

At about 2 weeks you will begin to notice a slight rosy to orange color on the surface. This is a sign that the process is going well.

Continue Washing

A full rosy surface will develop over time. The complex bacteria/mold surface will not only keep other unwanted molds at bay but will provide a rather aromatic (in a good way) quality that enhances the cheese.

At this point the washing only needs to be done again when an unwanted mold appears. Do not allow this rind to become too moist (excessively sticky or swampy) or too dry. If too dry you may find that the surface may crack, scale, or even begin to exfoliate or lift.

The cheese can now be aged for 4-6 weeks and it will be ready for your table (longer for a stronger cheese).

The amount of washing of the rind, the temperature, moisture control, and the amount of aging time will determine how much character the cheese develops.

If you would like a mild cheese, keep the aging short and be more aggressive at washing the developing rind away when washing. Try to keep the rind thin.

If you want your cheese to have a lot of character, then longer aging and developing a good healthy rind are the way to go.
