Strawberry shortcakes
The sumac will work just as
wonderfully with strawberries.

Stone-fruit shortcakes
Bypass berries altogether and
macerate slices of ripe peaches
or plums.


Add the kefir to the flour mix and toss together with gentle intent
to make a shaggy/clumpy dough. Don’t overmix – you’ll get tough
biscuits. Add a sprinkle of extra kefir if it needs – kefir can vary in
viscosity (and therefore) moistening power.

Place the clumpy dough mass on a lightly floured surface, clean your
fingers and then press the dough into a rectangle around 25 cm ×
10  cm (10 in × 4 in). Push a bench scraper against the sides to keep
the edges neat. Fold into thirds like a doughy business letter, then pat
out again to 25 cm × 10 cm (10 in × 4 in).


Feel free to roll with a pin if that feels more comfortable.

Trim 1–2 mm (116 in) off all the edges to allow for an unimpeded edge
crust rise. Cut into six even bars and space 2 cm in) apart in a row
on the baking tray. You can freeze them at this point and bake them
later/the next day.

Freezing is a helpful prep step and gives the baked shortcake more
defined  edges.

Bake for 12–15 minutes, until the shortcakes are deep honey golden
(internal temperature 90°C/195°F). The probe may look gummy with
dough but the biscuit will continue to cook as it rests post-bake. Cool
completely for 30 minutes before filling.

While they cool, hand whip (my preferred method, but beaters are
fine) the kefir cream filling ingredients together to billowy soft peaks
and keep chilled.


To fill, split each shortcake with small serrated knife. Spoon a generous
spoonful of the macerating blackberry syrup on each exposed crumb
side. Divide the berries between the bars and top with a luxurious
scoop of the kefir whip.
