Preparing and Setting the Milk

Begin by gently warming the raw milk to the optimal temperature for culturing, which is typically around 85°F (29°C). This temperature encourages the growth of the starter culture without compromising the milk’s natural enzymes. It is essential to use a reliable food-grade thermometer to maintain accuracy during this step.

Once the milk reaches the desired temperature, add the starter culture. This culture, containing lactic acid bacteria, initiates the fermentation process that develops the cheese’s flavor and texture. Stir the culture evenly throughout the milk to ensure uniform acidification.

After inoculating the milk, allow it to ripen by incubating it at the set temperature for 30 to 60 minutes. During this period, the bacteria convert lactose into lactic acid, lowering the pH and preparing the milk for coagulation.

Coagulation and Cutting the Curd

After the ripening phase, add the rennet, an enzyme that causes the milk proteins to coagulate and form a gel-like curd. Use the recommended amount of rennet based on the volume of milk; too little will delay setting, while too much can produce a brittle curd.

Stir gently for about 30 seconds to distribute the rennet evenly, then stop to allow the curd to set undisturbed. Setting time varies but usually takes 30 to 45 minutes. The curd is ready when it yields a clean break—when a knife inserted into the curd produces a clear split without sticking.

Cut the curd into uniform cubes, typically about 1/4 to 1/2 inch (6 to 12 mm) in size. This size affects moisture content; smaller cubes release more whey, leading to a firmer cheese, while larger cubes retain more moisture for a softer texture.

Cooking and Washing the Curd

Gently heat the curds to encourage further whey expulsion and firming. Gradually raise the temperature to approximately 102°F to 105°F (39°C to 41°C) over 30 minutes, stirring carefully to prevent matting.

Once the target temperature is reached, maintain it for an additional 30 minutes, continuing to stir slowly. This cooking step influences the texture and moisture level of the final cheese.

In some cheddar recipes, a washing step is employed to remove excess lactose and create a milder flavor. This involves replacing some of the whey with warm water at the cooking temperature. Washing also affects acidity and texture.

Draining and Cheddaring

After cooking, drain the whey from the curds using a cheesecloth-lined colander or a fine mesh strainer. Allow the curds to rest briefly to expel additional whey.

The cheddaring process is unique to cheddar cheese and involves stacking slabs of curd to expel whey and develop texture. Cut the curds into large blocks approximately 1 to 2 inches thick. Stack these blocks on a clean surface, turning them every 10 to 15 minutes for about 2 hours. This action helps drain whey and encourages acid development, contributing to the cheese’s characteristic flavor.

Milling and Salting the Curd

Once cheddaring is complete, mill the curds by breaking them into small pieces, typically around 1/4 inch (6 mm). Milling exposes more surface area, facilitating even salt absorption.

Salt is then added to the milled curds for flavor enhancement, moisture control, and preservation. The amount of salt varies but commonly falls between 1.5% and 2% of the curd weight. Salt also influences the final texture and microbial activity.

Distribute the salt evenly by mixing thoroughly but gently to avoid crushing the curds.

Preparing Raw Milk for Cheese Making

Raw milk is the foundational ingredient for crafting authentic cheddar cheese. Ensuring the milk is fresh and handled with care is paramount for the best flavor and safety.

Selection and Handling:

  • Use milk from healthy, well-managed cows to avoid contamination and off-flavors.
  • Strain the milk through a fine cheesecloth or filter to remove any debris or impurities.
  • Maintain the milk at a temperature between 33°C to 35°C (91°F to 95°F) for optimal bacterial activity.

Optional Pasteurization Considerations:

Although raw milk is traditionally unpasteurized, some cheesemakers prefer to gently heat the milk to 63°C (145°F) for 30 minutes to reduce pathogens without significantly altering flavor. If you choose to pasteurize, cool the milk back to the target fermentation temperature before proceeding.

Adding Starter Culture and Rennet

The addition of starter cultures and rennet initiates acidification and coagulation, critical steps in cheddar cheese production.

Ingredient Purpose Typical Amount Notes
Mesophilic Starter Culture Convert lactose into lactic acid, developing acidity and flavor 1/4 tsp per gallon (3.8 L) of milk Ensure culture is fresh and stored correctly
Liquid or Tablet Rennet Coagulates milk proteins, forming curds 1/4 tsp liquid or 1 tablet per gallon Dilute in cool, non-chlorinated water before adding

Procedure:

  • Warm the milk to 32°C (90°F), ideal for mesophilic cultures.
  • Sprinkle the starter culture evenly over the surface of the milk and allow it to rehydrate for 2 minutes, then stir gently for even distribution.
  • Allow the milk to ripen for 45 minutes to develop acidity.
  • Add the diluted rennet and stir gently for 30 seconds to mix thoroughly.
  • Stop stirring and let the milk coagulate undisturbed for 30 to 45 minutes until a clean break is observed.

Cutting and Cooking the Curds

Once the milk has set, cutting and cooking the curds facilitate whey expulsion and curd formation necessary for cheddar cheese texture.

  • Cutting: Using a long knife or cheese harp, cut the curd into 1 cm (1/2 inch) cubes. This increases surface area for whey drainage.
  • Resting: Allow the curds to rest for 5 minutes to firm slightly.
  • Cooking: Gradually heat the curds to 38°C (100°F) over 30 minutes, stirring gently and continuously to prevent matting.
  • Maintain the temperature and stir for an additional 30 minutes to expel more whey and firm the curds.

Proper cooking results in curds that are firm but elastic, ready for cheddaring.

Cheddaring the Curds

Cheddaring is a unique process that develops the texture and acidity characteristic of cheddar cheese.

  • After cooking, allow curds to settle and drain off whey for 5 minutes.
  • Transfer curds onto a clean, flat surface or draining table.
  • Cut the curd mass into slabs approximately 2.5 cm (1 inch) thick.
  • Stack the slabs on top of each other every 10 minutes, turning each stack 90 degrees to promote even acid development and whey drainage.
  • Continue this process for 2 to 3 hours until the curds reach a pH of approximately 5.2.

Use a pH meter or pH strips for accuracy, as acidity controls flavor and texture.

Milling, Salting, and Pressing Curds

Once the cheddaring process is complete, the curds are milled, salted, and pressed to shape and preserve the cheese.

  • Milling: Break the curd slabs into small pieces about 1 cm (1/2 inch) in size. This increases surface area for salt absorption.
  • Salting: Add non-iodized cheese salt at approximately 2% of the curd weight. Mix thoroughly but gently to ensure even distribution.
  • Pressing: Transfer salted curds into a cheese mold lined with cheesecloth.
  • Press at 10 to 15 psi (pounds per square inch) for 15 minutes to consolidate the curds.
  • Remove from press, flip the cheese, and re-dress with cheesecloth.
  • Press again at 20 psi for 12 hours, then increase to 40 psi for 12 to 24 hours to expel whey and form a solid cheese block.
