    • wholemeal flour 250 g
    • plain flour 250 g
    • bicarbonate of soda 1 tsp

A chemical reaction on a clock

Bicarbonate of soda plus the lactic acid in buttermilk gives carbon dioxide, water and sodium lactate. Unlike yeast, that reaction is nearly instantaneous and it does not renew. Every minute the dough sits on the bench is gas lost to the air rather than trapped in the crumb, which is why speed matters more than technique here. It also explains the loaf’s texture — coarse and slightly crumbly, because there is no gluten network holding fine bubbles.

Notes

  • Weigh the bicarbonate if you can. Too much and it tastes soapy with a yellowish crumb.
  • The dough should be soft and sticky, closer to a scone mix than a bread dough. Dry dough bakes tight.
  • It is at its best for about six hours, then it belongs in a toaster.

Try butter, 30 minutes, braise, or an ingredient you need to use up.
