Practical Uses for a 728 Minute Timer
People use a 728 minute timer for very different tasks, for example:
- Overnight Marinade: Meat and tofu absorb more flavour when they marinate for 8 to 24 hours. Set the countdown and plan the next meal.
- Cold Fermentation: Sourdough and pizza dough develop more flavour during a long, cold proof in the fridge.
- BBQ & Smoking: Pork shoulder, ribs and brisket smoke low and slow for many hours. The 728 minute timer reminds you to check the temperature and wrap the meat.
- 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.
