The present subject matter relates to a continuously operating metering and mixing machine (1) for producing a starting solution for sweets, particularly candies. The machine (1) includes a first supply path (2) for supplying a first liquid component (4) for the sweets, a second supply path (3) for supplying a second powdered component (5) for the sweets, and a mixing assembly (6), into which the first supply path (2) and the second supply path (3) each open. The mixing assembly (6) homogeneously mixes the first liquid component (4) and the second powdered component (5) in order to obtain the starting solution. Further, the machine (1) includes a first quantity detection unit (7) disposed in the first supply path (2) for continuously detecting a supplied quantity of the first liquid component (4), a second quantity detection unit (8) disposed in the second supply path (3) for continuously detecting a supplied quantity of the second powdered component (5), a first delivery device (9) disposed in the first supply path (2) for continuously delivering the first liquid component (4), and a second delivery device (10) disposed in the second supply path (3) for continuously delivering the second powdered component (5).
