1. Gather supplies: To make red food colouring, you will need a few basic items such as beetroot, a fine mesh strainer, a medium-sized pot, a spoon, a small dish and a reusable container for storing the colouring.

2. Prepare the beetroot: Wash and peel one large beetroot, then chop it into small pieces.

3. Boil the beetroot: Place the chopped beetroot into the medium-sized pot, and add enough water to cover it. Bring the water to a boil and then reduce heat, simmering for approximately 30 minutes or until the water turns a deep shade of red.

4. Strain the liquid: Drain the liquid from the pot through the fine mesh strainer into the small dish, ensuring that no beetroot pieces pass through.

5. Cool down: Set aside and allow the red liquid to cool down to room temperature.

6. Test concentration: Depending on your desired shade of red in your final dish, you might require more or less concentrated food colouring. If you find that your red colouring is too dark or too weak, adjust as needed by either diluting it with additional water or boiling it further to intensify its concentration.

7. Decant into a container: For easy storage and use, pour the cooled red food colouring into your reusable container.

8. Label your container: Don’t forget to label your container clearly with “red food colouring” and include an expiration date (typically six months from preparation) to ensure quality and safety during future usage.

9. Refrigerate: Store your new homemade red food colouring in the refrigerator for optimal preservation.

10. Use as needed: When you need to add some color to your dishes or baked goods, simply use your homemade red food coloring as required. Integrate as much or as little of the coloring as desired, stirring it thoroughly into your foods.

By following these ten simple steps, you can easily make your own natural red food colouring at home. Not only is it cost-effective, but you also avoid any artificial additives that are often found in commercial food colourings. Enjoy using your homemade red food colouring to create vibrant and beautiful dishes!
