Models of single-field inflation which include non-attractor phases of evolution can amplify the spectrum of curvature perturbations at a level sufficient for producing primordial black holes. We point out universal features of these models with respect to the frequency profile of the curvature spectrum, and the statistics of the corresponding higher order correlation functions. We then discuss a method for testing such universal features by cross-correlating CMB mu-distortions with CMB temperature fluctuations. This approach would allow us to probe distinctive properties of inflationary PBH scenarios using well-understood CMB physics.
