  Two-particle azimuthal correlations allow one to study high-$p_{\rm T}$
parton fragmentation without full jet reconstruction. Enhancements of the
azimuthal correlations are seen at $\Delta \varphi \approx 0$ and $\Delta
\varphi \approx \pi$, resulting from back-to-back jet fragmentation in the
parton center-of-mass system. We present the current status of the study of
correlations between charged trigger particles and associated strange baryons
($\Lambda$) and mesons (K$_{S}^{0}$) in pp collisions at $\sqrt{s}$ = 7 TeV. A
data-driven feeddown correction for $\Lambda$ is also presented, which could
allow a more accurate calculation of the primary $\Lambda/$K$_{S}^{0}$ ratio in
jets and the underlying event.
