Live coding performance starting from a white screen is commonly termed from scratch. In this contribution, we present some thoughts about the possibilities and consequences of this technique, based on our experience as members of the live coding communities of Mexico City and Barcelona. For that, we described from scratch rules and definitions of each community and then, we comment on how this practice began at each place. We finish the text discussing why we consider that live coding from scratch is a technique whose practice can be used as an epistemic tool, through which new creative spaces and limits are explored.
