Tried this tonight, used 50:50 wholemeal rye & strong wholemeal. Think it might of been a touch wet as it stuck like sh!t to a blanket when rolling out. Fell back to the old roll it out between cling film trick. Added some garlic purée and chopped chilli to the mix too but lost the flavours so will add them to butter next time.
Just fired the sous vide for tomorrows pulled pork.
