Sift 1½ pints of flour; add a pinch of salt, 1 teaspoonful of soda mixed with 1 pint of sour milk. Mix to a soft dough. Lay on a well-floured baking-board and roll 1 inch thick. Cut with a round cake-cutter and bake on a hot greased griddle until brown on both sides. Serve hot with butter.
A plain soda scone cooked on the griddle rather than in the oven — no fat, no sugar, no egg. The whole thing hinges on griddle heat and on not drowning the flour in liquid.
- The measurementsA pint here is the American 16 oz pint, so 1½ pints of flour is 3 cups (about 13 oz) and 1 pint of sour milk is 2 cups. That ratio gives a batter, not a dough — add the milk gradually and stop as soon as it comes together softly, which will likely take around 1¼ cups.
- Sour milkSour milk in this period was raw milk left to clabber, mildly acidic and slightly thickened. Cultured buttermilk is the direct substitute; milk soured with a tablespoon of lemon juice or vinegar per cup also works, though it is thinner.
- Soda without acid is bitterOne teaspoon of soda is right for roughly 2 cups of buttermilk, so if you scale the liquid down, scale the soda too — about ½ teaspoon for 1¼ cups. Excess soda leaves a soapy, metallic taste and a yellowish crumb.
- Griddle temperatureMedium to medium-low, around 350F on an electric griddle, rather than the frankly "hot" griddle the recipe calls for. Rounds an inch thick will need something like 5 to 7 minutes a side to cook through; too hot and the outside browns in a couple of minutes while the centre stays raw and gummy.
- Roll thinner if unsureTraditional girdle scones are usually rolled closer to ½ or ¾ inch, which cooks reliably. At the full inch, press the finished scone at the edge — it should feel springy, not doughy — or split one open to check.
- HandlingSoda dough starts reacting immediately. Mix, roll, cut and get them on the griddle without pause; the second batch will rise noticeably less than the first.
- YieldAround 7 to 9 scones from a 2½-inch cutter at the full inch thick, more if rolled thinner. They are at their best within minutes of coming off the griddle, split and buttered while still steaming; reheat leftovers on the dry griddle rather than in a toaster.
Griddle scones — girdle scones in Scots, the girdle being the flat iron plate hung over a peat fire — predate the domestic oven in much of Scotland, and the technique long outlived it. Where a household had no reliable oven, the daily bread was a flat cake cooked on iron: bannocks, oatcakes, and these soft wheaten rounds. The chemistry is equally period-specific. Sour milk plus bicarbonate of soda was the standard leavening of the nineteenth-century kitchen, cheap and instantaneous, and it survived in scone recipes long after commercial baking powder became common because the buttermilk tang is part of the flavour. The origin of the word itself is unsettled; it is variously traced to Dutch schoonbrood, fine white bread, and to Gaelic sgonn, a lump or block. A book organised as one dish a day from a different nation naturally reaches for Scotland's most portable culinary signature, and the scone was already that.
