      abstract     = {The emission of very-high-energy (VHE) photons (⁠|$E\
                      \gt\ 100\ \mathrm{GeV}$|⁠) in blazars is closely connected
                      to the production of ultra-relativistic particles and the
                      role of these γ-ray sources as cosmic particle
                      accelerators. This work focuses on a selection of 22 γ-ray
                      objects from the 2BIGB catalogue of high-synchrotron-peaked
                      sources, which are classified as blazar candidates of
                      uncertain type in the 4FGL-DR2 catalogue. We study these
                      sources by means of a re-analysis of the first 10 yr of
                      γ-ray data taken with the Fermi-Large Area Telescope,
                      including the attenuation by the extragalactic background
                      light. Their broad-band spectral energy distributions are
                      also evaluated, using multiwavelength archival data in the
                      radio, optical, and X-ray bands, in terms of one-zone
                      synchrotron-self-Compton models, adding an external Compton
                      component when needed. Out of this analysis, we identify 17
                      new extreme high-synchrotron-peaked (EHSP) candidates and
                      compare their physical parameters with those of prototypical
                      EHSP blazars. Finally, the resulting models are used to
                      assess their detectability by the present and future
                      generation of ground-based Imaging Atmospheric Cherenkov
                      Telescopes. We find two VHE candidates within the reach of
                      the current and next generation of Cherenkov telescopes:
