This look of this cake really makes my mouth water, and I definitely want to make it! Question: Does the sourdough starter in this recipe add "lift" to the cake, and if so, why add any baking powder or baking soda at all? Can sourdough starter be used as a sole leavening substitute for any cake or cookie recipe? Thank you! DK Hi - I'd say if the sourdough starter adds lift, it would be insignificant. And I wouldn't say you could use starter solo to leaven cakes or cookies - unless perhaps you experimented with letting the cake sit for hours to rise which, in my opinion, could compromise the flavor, due to the milk. eggs, and other perishables in the recipe. Hey, experimentation sometimes yields wonderful and unexpected results though, right? Give it a try, let us know what happens. PJH
