The general procedure involves first removing or softening the outer coat of the castor beans (some recipes suggest soaking them) and cooking the beans. Next, the beans are mashed and filtered. Then solvents are added to extract the ricin from the solution ... and congratulations, you’ve just made ricin.

(I tried to find what type of solvent, but no one has specified it, help)
