I made this bread yesterday. It took me a couple of goes to get it right but the 2nd attempt was utterly divine. I generally use a sponge for my bread but you can use your favoured bread dough mix.
The sponge
3g fresh yeast (I guess around 1.5g of dried)
150g water
75 g strong white flour
75 g Stoneground wholemeal flour
303g total Mix together to form a soft sponge and place in a bowl with plenty of room for expansion and cover with a lead or plastic bag. Leave at room temp to ferment for 16-48 hours
Mushroom mix
100g of boiling water
10g dried porcini mushrooms
50g brown-cap mushrooms or something else you prefer - firmer mushrooms are favoured over the watery ones such as oyster
Leave to soak for at least 1/2 hour - I left mine overnight and then drained them, keeping the water for my bread ..
chop very briefly in the TMX. You want pieces not a puree.
The final dough
225g sponge
150g strong white flour
75g stoneground wholemeal flour
4g sea salt
15g olive oil
105g water - I used the mushroom soaking water to infuse that extra mushroom aroma
Mix all ingredients together and knead until the dough is silky and stretchy - around 2-3 minutes in the TMX. I always do the window pane test on my dough so I'm not exact on times. I also think that kneading times vary a little depending on the weather, how long the sponge has been fermenting etc. Cover and allow to rise for an hour or so - until dough has approximately doubled in size.
Knock back the dough and press and stretch it until it is about 1-1.5cm thick. Spread the mushroom mix over it and then fold the dough over repeatedly in order to distribute the mix fairly evenly . I found the dough really difficult to work with at this point so just did the best I could then divided into 2. Place the rolls/loaves onto a baking tray lined with baking parchment (they DO stick to baking trays), cover and leave in a warm place to prove.
Bake at 190c for 20-25 minutes
When they were straight out of the oven I drizzled evo on them - it should be garlic infused oil but I'd had a bit of a disaster with the garlic puree on my first attempt so didn't bother ...
I'll try and get a photo up but ones already been eaten and the other is in the freezer ...
