I’m using variants of Hugh Fearnley-Whittingstall’s Guardian recipe from a year or two ago – it’s on line
Here’s my notes
For the sponge – midday ish
About 150ml active starter (see recipe above)
250g strong flour (white, wholemeal or a mixture of the two)
275ml warm water
For the loaf – evening
300g strong bread flour (white, wholemeal or a mixture), plus more for dusting
1 tbsp rapeseed or olive oil
10g fine sea salt
Rising overnight in fridge
Prove from first thing 1.5-3 hours
Bake as normal – hot as it’ll go for 10-12 minutes then 35-40 minutes at 180C
