For as long as we do this, we keep learning new lessons. This week's lessons were all about consumables.
1) While preservatives might not be desirable in groceries at home, they definitely are in consumables. Trader Joe's is fine, but they're famous for no preservatives. Result: We have four cases of stale tortilla chips.
2) In your air-conditioned pantry, order food by likelihood of spoilage.
3) Don't cross tours. The box of "Pate a PIzza" bought in Togo isn't good 1.5 years into your next tour.
4) Watch the cereal. When your kids have 12 boxes of cereal open simultaneously, that's too much variety.
