  Measurements of the semi-inclusive distribution of charged jets recoiling
from a trigger hadron in pp and Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ =
5.02 TeV are presented. This technique provides precise, data-driven
subtraction of the large uncorrelated background in jet measurements. It
uniquely enables the exploration of medium-induced modification of jet
production and acoplanarity over wide phase space, including low transverse
momentum ($p_\mathrm{T}$) and large resolution parameter ($R$) jets. This
proceeding reports the measurements of medium-induced jet energy redistribution
through the comparison of trigger-normalized recoil jet yields in pp and Pb--Pb
collisions, and for jets with different $R$.
