We consider deformations of Script N= 1 superconformal field theories that are AdS/CFT dual to Type IIB string theory on Sasaki-Einstein manifolds, characterised by non-zero vacuum expectation values for certain baryonic operators. Such baryonic branches are constructed from (partially) resolved, asymptotically conical Ricci-flat Kähler manifolds, together with a choice of point where the stack of D3-branes is placed. The complete solution then describes a renormalisation group flow between two AdS fixed points. We discuss the use of probe Euclidean D3-branes in these backgrounds as a means to compute expectation values of baryonic operators. The Y p, q theories are used as illustrative examples throughout the paper. In particular, we present supergravity solutions describing flows from the Y p, q theories to various different orbifold field theories in the infra-red, and successfully match this to an explicit field theory analysis.
