We have investigated numerically the electron addition spectra in quantum dots containing a small number (N < 11) of interacting electrons, in presence of strong disorder. For a short-range Coulomb repulsion, we find regimes in which two successive electrons enter the dot at very close values of the chemical potential. In the strongly correlated regime these close additions, or pairing, are associated with electrons tunneling into distinct electron puddles within the dot. We discuss the tunneling rates at pairing, and we argue that our results are related to a phenomenon known as "bunching", recently observed experimentally.
