Why Use a 675 Minute Timer?
A 675 minute timer is useful in many situations:
- Cold Fermentation: Sourdough and pizza dough develop more flavour during a long, cold proof in the fridge.
- Babysitting & Care Shifts: Know exactly how long until the parents return or the next shift takes over.
- Day Trip: Keep an eye on the clock during a day trip, a city tour or a hike so you catch the last train home.
- BBQ & Smoking: Pork shoulder, ribs and brisket smoke low and slow for many hours. The 675 minute timer reminds you to check the temperature and wrap the meat.
- Long-Haul Flight: Count down a long-haul flight or a night train and see how much travel time is left.
