  We provide new evidence for the gauge/string duality between the baryonic
branch of the cascading SU(k(M+1)) \times SU(kM) gauge theory and a family of
type IIB flux backgrounds based on warped products of the deformed conifold and
R^{3,1}. We show that a Euclidean D5-brane wrapping all six deformed conifold
directions can be used to measure the baryon expectation values, and present
arguments based on kappa-symmetry and the equations of motion that identify the
gauge bundles required to ensure worldvolume supersymmetry of this object.
Furthermore, we investigate its coupling to the pseudoscalar and scalar modes
associated with the phase and magnitude, respectively, of the baryon
expectation value. We find that these massless modes perturb the
Dirac-Born-Infeld and Chern-Simons terms of the D5-brane action in a way
consistent with our identification of the baryonic condensates. We match the
scaling dimension of the baryon operators computed from the D5-brane action
with that found in the cascading gauge theory. We also derive and numerically
evaluate an expression that describes the variation of the baryon expectation
values along the supergravity dual of the baryonic branch.
