Hard splittings in the evolution of a hard scattered parton may be modified by the presence of a dense strongly interacting medium. Grooming procedures can be used to isolate such hard components of a jet and allows one to focus on the two subjets resulting from a sufficiently hard partonic splitting. Measurements of the symmetry parameter (z(g)), angular separation (R-g) and number of splittings (n(SD)) of Soft Drop groomed jets are reported as measured with the ALICE Detector in pp and Pb-Pb collisions at root s = 7 TeV and root s(NN) = 2.76 TeV, respectively. The use of recursive splittings and their mappings to identify interesting regions of phase space in the z(g) - Rg plane are also discussed.
