Savanyúság — the sour-piquant that refreshes and balances the fat

In summer in Budapest, my mother would place a large glass jar on the windowsill in full sun, with a slice of rye bread floating inside — that's what starts the fermentation, a chain reaction whose chemistry I only understood much later. In three or four days of heat, the water turns cloudy and the cucumbers become crunchy and tangy. You eat them chilled alongside a fatty dish, and the balance is perfect: a bit like a function and its derivative, one calls for the other. As a child, I would check the jar every morning to see if it was ready.

How it was made : Sun lacto-fermentation (kovászos uborka, literally "sourdough cucumber") is a traditional Hungarian summer technique, distinct from vinegar pickles. Before refrigerators, it was a way to transform and briefly preserve summer cucumbers while obtaining a living, probiotic accompaniment.
