Accretion disks are a common structure in the universe. Young stars grow by accreting the material from the disk that also forms planets. Only in recent years that it is possible to study the detailed structure of these young disks. Yet, it is still not fully understood how disks form around young protostars. By comparing the observed dust and gas structures to numerical models, it might give insights to how the material is transported from the early stages of star formation to the young planet-forming disk. In order to obtain a more complete picture, the dust, gas and ice composition of the young disk is compared with meteorites. The history and physics of star formation can be better understood by knowing the ingredients (dust, ice and gas) of the young disk.
