In the present work we have considered a modified gravity dubbed as "logarithmic f(T) gravity" and investigated the behavior of Ricci dark energy interacting with pressureless dark matter. We have chosen the interaction term in the form Q∝ Hδρₘ and investigated the behavior of the Hubble parameter H as a function of the redshift z. For this reconstructed H we have investigated the behavior of the density of the Ricci dark energy ρRDE and density contribution due to torsion ρₜ. All of the said cosmological parameters are seen to have increasing behavior from higher to lower redshifts for all values of c² pertaining to the Ricci dark energy. Subsequently, we observed the equation of state parameter wRDE in this situation. The equation of state parameter is found to behave like phantom for all choices of c² in the Ricci dark energy.
