I made this today.
I made a few changes.
I used 2 tsp of traditional dried yeast as I had no fresh
I added 20 g butter and 5g salt.
I replaced 50gm white flour with 50 gm of stoneground whole meal.
They were delic, thank you.
Instead of a bowl of water in the oven I throw in an egg cupful of water as I close the door. But do not want to recommend this incase your ovens can't cope. Mine is an Aga and I t is fine (or has been up to now!)
