A month ago, Migros had a 40% off sale on flour, only 1sfr/kilo instead of 1.70sfr/kilo (that's about $.40/pound instead of $.70/pound). So I put my baby in the bjorn and carted home 40 kilos on my stroller. Why? I do plan to bake a lot. But also, my church strongly encourages emergency preparedness, particularly food and water storage. I'm not doing well in this department. I have a ransacked 72 hour kit, one week of water (1 gallon per person per day), and a small assortment of random can goods collecting dust in the cellar. Occasionally, I get motivated and stock up on whatever happens to be on sale. Forty kilos seemed like a reasonable amount at the time, but now that it has been sitting in my hall for four weeks, I'm not so sure. I've already baked my way through 4 kilos this month, so we'll see if I use it all before the expiration date. I must be more methodical in building up my long-term food supplies.
P.S. Freezing flour for a couple days before storing at room temp will kill any weevils that might already be present in the flour. Here are more tips on storing flour.
