Soy Milk Whole Wheat Sourdough Waffles

These waffles are the dairy-free, egg-free way to put a sourdough starter to work outside of bread. The starter and soy milk get mixed with half the whole wheat flour and left out overnight, where the wild yeast bubbles away and turns the batter tangy and full of complex flavor that no buttermilk shortcut can replicate.

The overnight ferment is the recipe’s whole personality. Without it, you’d get fine whole wheat waffles. With it, you get waffles that taste like proper sourdough bread, with the same yeasty depth and a slight tangy edge that pairs beautifully with maple syrup or fresh fruit.

In the morning, the rest of the flour, baking soda, and powder get stirred in and the batter goes straight onto a hot waffle iron. The instant lift from the chemical leaveners plus the developed flavor from the long ferment is the whole game.

Pro Tips

• Use a healthy, active sourdough starter that’s been fed within the last 12 hours. Sluggish starter won’t ferment the batter overnight and you’ll lose the tang.
• Cover the bowl loosely with a clean towel during the overnight rest, not plastic wrap. The yeast needs to breathe a little and you don’t want pressure to build up.
• Spread the batter to the edges of the waffle iron quickly. Sourdough batter is bubbly and starts deflating as soon as you pour, so move fast.
• Cook until gently browned for a crisp exterior. Pulling early gives soft, pale waffles; cooking too long turns them dry and bitter.
• Stir in 1 cup of fresh blueberries or diced peaches at the end (the recipe suggests it) for a sweet variation.

Variations

• Use almond, oat, or coconut milk in place of soy for a different non-dairy version.
• Add 1 tablespoon of maple syrup and 1 teaspoon of vanilla extract for a sweeter dessert-style waffle.
• Stir in a teaspoon of cinnamon and ½ cup of chopped pecans to the morning batter for a spiced, nutty version.
