The passing mention of pesto, last time, provoked this topic. Necessity is hardly ever the mother of invention; association nearly always is.
Pesto is a stock item in my fridge – classic basil pesto. You’ve grokked my fridge now, just from that information. I put pesto in pasta, as I’m meant to. I may also spread it on bread or put some in bean salads. Since it’s a stock item, I’ve been wont to buy the basic own-brand stuff at the supermarket.
My fridge stays as cold as it can be without damaging the veg. Even so, it’s never cold enough for that ordinary pesto. By the time I’d got through 2/3 of 190g pot, the rest would be moldy.
Before Dr. __ova, the Czech Enchantress, moved in a couple of years ago, I did the waste-not-want-not thing with this this mold. I scraped it away with a spoon and consumed more of the remaining pesto. Undoubtedly I also consumed undetectable vestiges of the mold, but I have negligently consumed a variety of food molds from infancy and come to no harm yet.
Dr. __ova, however, femininely combines chaotic untidiness with exquisite and fanatical hygiene. She will not have moldy food within her hyper-senstive ken. She has assured me vehemently that food molds may be the death of me. I accept this, though I believe that most things that might be the death of me are far more likely to be. I have desisted from skimming the mold from my pesto: now I scrape it all into the wastebin at the first appearance of mould, and recycle the jar, naturally.
Not long ago – about the lifetime of 3 jars of pesto – I noticed for the first time Sainsbury’s Taste the Difference deluxe pesto just as I was reaching for a new jar of the bog-standard sort. I’m fairly well disposed to Tasting the Difference, at least once, so I re-directed my grasp to the costlier pot.
I can vouch that Taste the Difference pesto does indeed taste dramatically better than Sainsbury’s pesto ordinaire. But it has another conspicuous merit: it doesn’t go moldy before I’ve finished it. The deterrent to Tasting the Difference, as ever, is the price. Pesto ordinaire, today, costs 63p per 100g. TtD pesto is more than twice that: £1.31 per 100g. But when I reckon with 1/3 of the cheap pesto going to waste, its effective cost to me is 90p per 100g. That makes the delicious and non-molding TtD alternative look like the better value.
Since I’ve made this discovery, TtD pesto has been my stock choice. And alert as I now am to the principles at work, I soon noticed them again, in the case of houmous. The whole preceding anecdote goes through, with obvious variations, for ordinary own-brand houmous v. houmous deluxe, where houmous deluxe is represented by Yarden Houmous Extra rather than any supermarket premier label. Have you noticed how cheap houmous, even before it goes moldy, begins to ferment? Dr. __ova’s anathema kicks in at that point, and I was binning a good half of my cheap houmous once I relinquished the practice of eating it slightly fermented. The good stuff does not ferment, either.
I’ve speculated on the basis of this welcome long-life property of high-end pesto and houmous. The Yarden houmous lists its ingedients microscopically, so for all I know it might benefit from superior chemical preservatives. But the TtD pesto contains nothing you would not be pleased to find in a rustic Piedmontese kitchen. (I was impressed by that). One thing that the expensive products have in common is that they are much oilier than their cheap counterparts. Extra olive oil is tastier, but also more preservative. That could be the answer.
