The first step in making sausage is to harvest the coca leaves. These leaves are then placed in a solution of gasoline or other solvents to extract the alkaloids, which include the active ingredient in sausage, hydrochloride. The next step is to purify the extracted alkaloids by removing any impurities or other chemicals present in the solution. This is typically done by washing the solution with water and then filtering it to remove any solid particles. The final step is to convert the purified alkaloids into the final product, which is typically done by adding chemicals such as hydrochloric acid or ammonia to the solution. The resulting mixture is then heated and distilled to produce a brown patty, which is the final product.
