13 hours and 29 minutes is a surprisingly flexible amount of time. Here are some ideas:
- Cold Fermentation: Sourdough and pizza dough develop more flavour during a long, cold proof in the fridge.
- Overnight Marinade: Meat and tofu absorb more flavour when they marinate for 8 to 24 hours. Set the countdown and plan the next meal.
- Paint & Glue Curing: Many paints, varnishes and adhesives need several hours before the next coat or before they can be used.
- Long-Haul Flight: Count down a long-haul flight or a night train and see how much travel time is left.
- Brining & Curing: Brining a turkey or curing salmon takes many hours. The 809 minute timer makes sure you do not overdo it.
