What Can You Do With a 818 Minute Timer?

A countdown of 13 hours and 38 minutes works well for situations like these:

  • Overnight Marinade: Meat and tofu absorb more flavour when they marinate for 8 to 24 hours. Set the countdown and plan the next meal.
  • 24-Hour Challenge: Game jams, hackathons and charity streams often run around the clock, and 13 hours and 38 minutes on a big screen keeps everyone motivated.
  • Brining & Curing: Brining a turkey or curing salmon takes many hours. The 818 minute timer makes sure you do not overdo it.
  • BBQ & Smoking: Pork shoulder, ribs and brisket smoke low and slow for many hours. The 818 minute timer reminds you to check the temperature and wrap the meat.
  • Cold Fermentation: Sourdough and pizza dough develop more flavour during a long, cold proof in the fridge.
