Today we jump back once again to simple recipes without preferment because I got some mails asking if the sourcream or yoghurt can be replaced somehow to make the recipe free of lactose or vegan. The obvious idea was to replace the yoghurt with soy yoghurt and that was what I was suggesting. But I don’t like to advice something I did not tested and so I bought some soy yoghurt. And just repeating a recipe is borrowing and so I started to create a new recipe. It contains a bit of rye flour which adds a hearty note to its flavour, the soy yoghurt give subtle sourness to the rolls. The crust is crisp, the crumb soft. And I can say that exchanging yoghurt with soy yoghurt works perfectly well!
