Very close in content to the other crêpe listing, so pick one rather than booking both. The batter rests, which is non-negotiable and is what stops them tearing, and the technique is pour-tilt-swirl before it sets. What I hadn't appreciated is how thin a proper crêpe is — considerably thinner than I'd been making, almost translucent — and that comes down to using less batter than instinct suggests rather than any special skill.
