We present a Fermi liquid approach to superconducting Kondo problems applicable when the Kondo temperature is large compared to the superconducting gap. To illustrate the theory, we study the current-phase relation and the Andreev level spectrum for an Anderson impurity between two-wave superconductors. In the particle-hole symmetric Kondo limit, we find aperiodic Andreev spectrum. Theperiodicity persists under a small voltage bias which however causes an asymmetric distortion of Andreev levels. The latter distinguishes the presenteffect from the one in topological Majorana junctions.
