Record, review, then act.
The system is deliberately small enough to fit into a normal household routine.
1. Record what matters
Add the foods that are easy to forget, not necessarily every grain of rice. Use locations and dates only when they improve the next decision.
2. Review once a week
Scan items needing attention before planning meals or shopping. A short, regular review is more useful than an elaborate setup that goes stale.
3. Keep or export
