Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sponge: Starts fermentation so the dough rises and develops flavour.
Rye flour: Adds a dense, earthy structure and flavour, with less gluten than white flour.
White flour: Provides gluten for structure and an open, elastic crumb.
Lard: Adds fat, which softens the crumb and gives a tender texture.
Sugar: Feeds the yeast and adds a little sweetness and browning.
