The color-singlet representation of lattice QCD with staggered fermions offers a framework to soften the sign problem at finite density. This allows for the computation of the complete QCD phase diagram at strong coupling as well as at $\mathcal{O}(\beta )$. Furthermore, the chiral limit is cheap and thermodynamic quantities such as the energy density and the pressure can be computed easily. Using recently obtained results on the nonperturbatively renormalised anisotropy $\xi (\gamma )$, we present first calculations of the energy density and pressure in the $\mu$-$T$-plane in the strong coupling limit.
