We used to live near the Mtkvari River, in a ground-floor apartment with a single window looking into our courtyard, which was a dirt parking lot. The sun never made it to our window but every morning at the crack of eight, a woman would wake us with the melodious croon of “ma-tso-ni, mat-so-ni!” And if that didn’t wake us, her incessant tapping on our window certainly did. The payoff, however, was a jar full of the thickest, creamiest, most refreshing homemade yogurt, with just a perfect hint of tartness. So, we would shuffle out of bed, open the window and exchange our empty jars with her full ones.
