Easy24 hours (about 40 min hands-on)1 × 900 g (2 lb) tin loaf

Folding a bowl of soaked oats into the dough gives a sandwich loaf with a tender, slightly creamy crumb that stays soft for days and slices thinly without crumbling. It is baked in a tin, so it has straight sides and square slices — perfect for toast and packed lunches.

Ingredients

  • 80 g rolled oats, plus extra for the top
  • 200 g boiling water (for the porridge)
  • 450 g strong white bread flour
  • 50 g wholemeal flour
  • 100 g active sourdough starter, at its peak
  • 270 g water at about 26°C
  • 20 g honey
  • 20 g unsalted butter, softened
  • 10 g fine sea salt

Contains: wheat (gluten), oats (gluten), milk.

Method

  1. Soak the oats. Pour the boiling water over the oats, stir, cover and leave for at least 1 hour (or overnight) until thick and cooled.
  2. Mix. Whisk the starter and honey into the 270 g water. Add both flours and mix until no dry flour remains. Cover and rest 30 minutes.
  3. Add salt and butter. Squeeze in the salt, then the soft butter, until fully absorbed.
  4. Fold in the porridge. After the first 30 minutes, add the cooled porridge and squeeze and fold it through until evenly distributed. The dough will be soft.
  5. Bulk ferment. Give three more sets of folds 30 minutes apart, then leave covered at 24–26°C until risen by about 50% — usually 4–6 hours from mixing.
  6. Shape. Grease a 900 g (2 lb) loaf tin. Shape the dough into a tight log, brush the top with water, roll it in oats and place seam-down in the tin.
  7. Final prove. Cover and prove at room temperature for 2–4 hours until the dough has risen about 1 cm above the rim — or refrigerate overnight and bake the next morning.
  8. Bake. Bake at 210°C (190°C fan) for 40–45 minutes until golden and 96°C in the centre. Turn out of the tin for the last 5 minutes for a crisper base and sides.
  9. Cool. Cool completely on a rack before slicing.
