Even with the full capabilities of ALMA, z>2 star-forming galaxies can only be studied at coarse resolution - however, strong gravitational lensing allows us to push the resolution and sensitivity limits by another order of magnitude. I will present a novel lens-modelling technique tailored specifically for radio/mm-interferometers such as ALMA and demonstrate the power of this technique by presenting the first high-resolution (50-100 parsecs) maps of dust and gas in a z~3 strongly lensed starburst from ALMA long baseline observations.
