After catching up with Gibraltarian M at 1369 in Central, I took an errand ramble around the neighborhood and popped into Mariposa Bakery on impulse. On the counter, unlabeled, was a basket of scones that turned out to be cheddar-scallion, one of my favorites. The friendly but somewhat overcaffeinated counterman cheerully rang me up. Smaller than the usual cafe bakery scone, but not so small as to make me feel cheated (see recent oatmeal scone developments at Diesel), Mariposa’s scones were light and moist. The cheddar flavor was subdued but attended by some tasty cheese crusts at the margins.
