Sourdough - The Ideal Bread For Powercut Baking

That other day when the power went off for nearly 24 hours... I discovered something else good about baking your own sourdough bread. We have an electric oven and I have already started some bread dough to rise when... the power goes "Phut".
Do not panic, say I to meself. You can make sourdough into a really "slow food". I did whack the bowl of dough in the still cold but non-functioning fridge and....
Next day, when the power came back, I did stab the little rascal back down a bit, waited for it to get back to room temperature... shaped it, proved it... and baked it.
No problem.
