I would like to carry about a weeks worth of food staples at a time. For instance, rice, beans, cous cous, potato flakes, pasta, spices, freeze dried hummus, oatmeal while buying other food on the road (when available) like produce, bagels, snacks, etc every couple of days. A couple questions:
1. Roughly what size stuff sack should I get to carry the amount of food described above? I was thinking something that would fill about half a rear pannier. Maybe 12 liters??
2. How are food odors managed? Special bags? Bags within bags?
