I spent €60 at the market this afternoon, plus €17 at my local organic butcher's, and €6 at the market yesterday during my lunch break (when there were different stalls including an organic bread stall that I didn't discover until after I'd bought bread. I'd have spent much more if my lunch break had been longer) . It's safe to say that my food budget has exploded this week.
I'm not going through an itemized list this time, but I do want to mention that some of these expenses were one-offs. The biggest extra expense was tortilla chips plus four kinds of dip to go with them; the plan is for me to reverse-engineer and then improve on the dip I like the best (which is probably going to be the chilli), so that's €8-10 that I'll only spend once. I also bought enough cheese to last for three weeks, plus fresh cilantro, which I usually do without.
I've located milk! But I didn't buy any as it was €1.30 for half a liter. Locally produced and organic, so probably very good, but the price was one I'd expect in a cafetaria, not in retail. I can technically afford to pay € 2.60 a liter for milk, but only if I still save money overall, which I'm not doing.
Going back to the original purposes of the experiment, I ended up buying a lot of things that weren't whole food staples but prepared foods: melba toast, the dips, chocolate nuts, the tortilla chips which by Michael Pollan's definition are edible, foodlike substances. So the experiment's purpose was defeated entirely and I might as well get those things from the supermarket again. On the plus side, shopping at the market is a lot more fun - you're outdoors, there are bargains to be had and new products to try, and the smells from some of those stalls is just divine. Goat cheese in particular taunts and tempts me whenever I pass it, as do Moritz's olives, sun-dried tomatos and feta.
Experiment over! It would have been fun and interesting to do this for a couple of months; describing your shopping in great detail is the sort of thing that's dull if you do it once, but becomes more interesting if you keep it up until patterns become visible. But the pattern that's showing up already is that I spend more and don't stick to the experiment's purpose, so to protect my wallet, I'm cutting it off here. I'll be splitting my purchases between the outdoors market and the supermarket like a sane person.
