Successfully making RCD homebrew has been billed as one of the easiest recipes in history. The amount of the now renowned "kitchen whizz smoothie" being out on bait has recently been halved. The results are still impressive. Common opinion suggests the virus is so potent, spreading it is elementary. One of the most interesting recent developments is that recipes may soon be a thing of the past. The virus is now moving rabbit-to-rabbit without human help. Farmers who are not spreading the virus on their properties have found RCD- infected carcasses.

The mixture is as simple as mixing rabbit livers, hearts, and lungs with water. Saline solution (9gms of common salt to each litre of water) is an optional medium. Officials say the ratio of water to rabbit is almost academic. The virus is so virulent that if infected rabbits in the blender, you will have a killer on your hands. Farmers are advised to wear a mask if possible because of the risk of contamination of other micro-organisms such as salmonella. If the virus-laden mixture is intended to be used on oats, some farmers have been soaking 50kg bags of oats in 1 litre of molasses with enough water to cover them. They are drained and then treated with RCD.

The RCD mixture is usually whisked with about 300mls of water then mixed with one litre of water to cover 50kg of oats. The RCD mixture is combined with oats by putting it all in a 200 litre plastic drum, and rolling it around the yard. For a 10 tonne aerial carrot drop on one farm recently they mixed hearts, lungs and livers from six rabbits, with one litre of water and whizzed it. They then diluted it with 20 litres of water, and sprayed it on to five tonnes of the carrots with the knapsack sprayer before it went through the carrot cutter. The process was repeated for the second five tonnes, and reportedly the results have been tremendous. The biggest danger to the vialbility of the virus is if it is heated or exposed to disinfectant or bleaches. Farmers are also being encouraged to let it spread naturally after the initial bait. Heat will kill it and disinfectant and bleaches will change the pH and potentially make it inactive. It should also be kept out of ultraviolet light.
