Blue cheese is unique among cheeses because it ripens from the inside out as a result of mould activity. The blue veins in blue cheese are created by the penicillium in the mixture. To make blue cheese at home, you will need a lot of patience and careful attention to detail. The process involves heating milk and cream in a stockpot to 88°F (31°C) and blending blue cheese and water. You can add food colouring to the mixture to make blue cheese. Colours like pink, orange, and yellow can be achieved using beet juice, paprika, and turmeric, respectively.

Using food colouring
While there are a variety of ways to dye cheese blue, using food colouring is a simple and effective method. Here is a step-by-step guide on how to dye cheese blue using food colouring:
Preparing the Cheese
Start by selecting the type of cheese you want to dye. It is important to note that different cheeses will absorb colours differently due to their varying fat and moisture contents. Harder cheeses, such as cheddar or gouda, may be easier to work with as they are firmer and less likely to crumble. Soft cheeses like mozzarella or cream cheese may be more challenging to dye but can still produce good results.
Choosing the Right Food Colouring
When it comes to choosing a food colouring agent, there are two main types: liquid and gel. Liquid food colouring is typically more watery and can be easily mixed into the cheese. Gel food colouring, on the other hand, is thicker and more concentrated, so a little goes a long way. It is important to select a brand that is designed specifically for food use and will not alter the taste of your cheese.
Mixing the Colour
Before adding the food colouring to your cheese, prepare the dye by mixing it with a small amount of water. This will help to evenly distribute the colour throughout the cheese. Add a few drops of blue food colouring to a bowl of water and stir until you achieve your desired shade of blue. You can also add a small amount of white vinegar to the mixture to enhance the colour absorption.
Dyeing the Cheese
Now it's time to add the colour to your cheese. Using a spoon or a butter knife, gently fold the cheese onto itself, incorporating the food colouring mixture a little at a time. Continue this process until the colour is evenly distributed throughout the cheese. You may need to adjust the amount of food colouring or water to achieve your desired shade.
Shaping and Storing
Once the cheese is evenly coloured, you can shape it as desired. Line a small container with plastic wrap, place your shaped cheese in it, and store it in the refrigerator until ready to serve. Your dyed cheese can be used as a colourful addition to dishes or as a fun snack on its own!
It is important to note that while food colouring can be a fun way to enhance the appearance of your cheese, it may not always be the healthiest option. Some artificial food colourings have been associated with potential negative health effects. Therefore, it is recommended to use natural food colouring or opt for naturally coloured cheeses whenever possible.

Using beetroot juice
While it is possible to dye cheese blue using beetroot juice, it is important to note that the process is not as simple as it may seem. Here is a step-by-step guide on how to use beetroot juice to dye cheese blue:
Preparing the Beetroot Juice:
Firstly, you will need to prepare the beetroot juice. Wash and scrub one or more beetroots thoroughly under running water. Remove the stems and leaves, as these parts are not needed for dyeing. Chop the beetroots into small pieces, considering the size of your juicer or blender. If using a juicer, process the beetroot chunks according to the device's instructions. If you're using a blender, blend the beetroot with a small amount of water (about 1/4 cup) until it reaches a liquid consistency.
Once you have extracted the juice, use a cheesecloth, nut bag, or thin dish towel to strain and squeeze the juice from the beetroot pulp. Be cautious, as beetroot juice stains easily! You can expect to yield approximately 3 tablespoons (45 ml) of juice from one beetroot. The juice can be frozen in ice cube trays or small jars for later use.
Dyeing the Cheese:
Now that you have prepared your beetroot juice, it's time to dye the cheese. This part of the process becomes experimental, as there are no precise instructions for dyeing cheese blue with beetroot juice. However, you can follow these general guidelines:
- Start with a small amount of beetroot juice and gradually increase as needed. The more juice you add, the deeper the hue will become.
- Combine the beetroot juice with your cheese. You may need to melt the cheese to facilitate even coloration.
- Stir or blend the mixture until you achieve a uniform colour.
- If you are aiming for a darker shade of blue, you can try adding a small amount of an acidic ingredient, such as lemon juice or vinegar, to the beetroot juice. Acids are known to alter the colour of beetroot juice, turning it from pink to blue.
- Keep in mind that the cheese's colour may change slightly as it dries, so it's essential to allow it to dry thoroughly before assessing the final colour.
Tips and Considerations:
- Beetroot juice is known to stain hands and surfaces easily. It is advisable to wear food preparation gloves and protect your work area with paper towels or old dish towels.
- While beetroot juice can be used as a natural dye, achieving a vibrant and stable blue colour may be challenging. The resulting colour may lean more towards pink or purple.
- If you desire a more permanent blue colour, you may need to explore alternative dyeing methods or use specialised dyeing equipment.
- Always follow proper food safety and handling procedures when working with fresh produce and cheese.
Remember, dyeing cheese blue with beetroot juice is an experimental process, and the results may vary. Feel free to adjust the process based on your specific requirements and the type of cheese you are using.

Using paprika
Paprika is a spice that can be used to dye cheese orange. While annatto is the most common colourant used in cheddar cheese, paprika is a natural alternative for those who prefer to avoid synthetic additives. To dye cheese with paprika, you will need to create a dye by simmering one tablespoon of the spice with one cup of water for 15 to 30 minutes, and then straining the mixture. This method of dyeing cheese will add flavour to the cheese, so it is important to consider how the paprika will impact the overall taste.
Paprika is not the only natural alternative to annatto for colouring cheese orange. Some cheesemakers also use turmeric or saffron to achieve a similar hue. These natural colourants provide additional nutritional benefits and can enhance the flavour profile of the cheese.
It is important to note that the process of dyeing cheese with paprika may not result in a vibrant orange colour. The lightness of the desired colour may require a larger quantity of dye or a longer simmering time. Additionally, the natural dye may not be as colourfast as synthetic alternatives and may fade or wash out over time.
When dyeing cheese with paprika, it is also crucial to consider the type of cheese being used. Some cheeses, such as paneer and queso fresco, are easier to make at home and can be dyed by first colouring the milk. However, for other cheeses, it may be necessary to add stabilizers to melt and reform the cheese after dyeing.
Overall, using paprika to dye cheese orange is a natural and flavour-enhancing alternative to synthetic colourants. By simmering the spice and water to create a dye, cheesemakers can add a unique hue and nutritional benefits to their product.

Using annatto
Annatto is a natural food colouring added to cheese to make it appear yellow, orange, or red. It is made from the seeds of the achiote tree (Bixa orellana), a small evergreen native to the tropical regions of South America, now grown in Brazil and the Philippines. The seeds have a red flesh that yields the yellow to orange colour in cheese. Annatto is commonly used in Latin American and Caribbean cooking and is added to cheese to create a visual impact.
To use annatto seeds to dye cheese, you can follow these steps:
- Soak 1/2 teaspoon of annatto seeds in 1 tablespoon of boiling water for an hour.
- The water will turn a deep orange colour.
- This coloured water can then be added to the cheese curds.
The amount of annatto added to the cheese will determine the final colour. A small amount will create a light yellow colour, while more annatto will result in a brighter orange or red hue. For example, using 1/2 teaspoon or 25 drops of annatto in 5 gallons of milk will produce a mild orange colour similar to what is typically found in a cheese shop.
It is important to note that annatto has been linked to rare cases of food-related allergies, so use it with caution when consuming or serving to others. Additionally, some people may detect a slight change in the flavour of the cheese due to the nutty, sweet, and peppery taste of annatto. However, for most people, annatto does not noticeably affect the flavour of the cheese.

Using turmeric
Although turmeric is usually associated with a bright yellow/orange colour, it can be combined with indigo to create a blue dye.
To dye cheese blue using turmeric, you will first need to create a turmeric dye. To do this, mix ground turmeric with water and vinegar and bring the mixture to a boil. You can also add some lemon juice to the mixture to enhance the colour. Then, simmer the mixture for an hour and strain the liquid through a coffee filter or muslin cloth to remove any remaining particles of turmeric.
Once you have your dye, you will need to create a homemade version of oleoresin by simmering the turmeric in oil and straining it to reduce the mustard flavour that turmeric usually imparts. Then, you can dye milk blue using your turmeric dye and make cheese from it. Some cheeses like paneer and queso fresco are easy to make at home.
It is important to note that the colour of the dye may not be exactly blue and may vary depending on the materials and quantities used. Additionally, turmeric is not the longest-lasting dye and may fade over time.
