In this Letter, we consider $t\\bar{t}H$ associated production in the dileptonic mode. We demonstrate that the difference in azimuthal angle between the leptons from top decays can directly reveal the CP-structure of the top-Higgs coupling with the sensitivity of the measurement substantiality enhanced in the boosted Higgs regime. We first show how to access this channel via $H \\to b\\bar{b}$ jet-substructure tagging, then demonstrate the ability of the new variable to measure CP.
