Making crispy sourdough waffles is our favorite thing to do on a Saturday morning. Last year, I purchased a professional grade waffle iron, which has seriously improved our waffle game, and made it possible for su to enjoy crispy waffles to begin with! The other most important aspect is the sourdough waffle batter. I’ve experimented with many different sourdough waffle recipes, but this one always comes out tasting the best. The waffles are fluffy with an airy texture on the inside, and deliciously crispy on the outside.

Tips

1. Cooking time

Cooking time in the waffle iron will depend on the temperature that you’re pre-heating your iron to, and will also differ model to model. Try out the cooking time with your first waffle, and adjust. 

2. Making crispy waffles

If you want crispier waffles, allow them to cook in the waffle iron for a little longer. However, watch out for burning. 

3. Use a Professional Grade Waffle Iron

Invest in a good-quality waffle iron to achieve the best crispiness and texture.

4. Overnight Fermentation:

Let the sourdough batter ferment overnight for a deeper, tangier flavor and better texture.

5. Avoid Overfilling

Use the right amount of batter for your waffle iron to prevent overflow and ensure even cooking.

6. Cook Until Golden Brown:

Cook the waffles until they are a deep golden brown for maximum crispiness. This may take a bit longer than usual, but the result is worth it.

7. Keep Waffles Warm:

If making multiple batches, keep the cooked waffles warm in a single layer on a wire rack in a low oven (around 200°F) to maintain their crispiness.

8. Adjust Consistency:

If the batter is too thick, add a bit of milk or water to achieve the right consistency. It should be pourable but not runny. If it’s too runny, add additional flour.

9. Serve Immediately:

Waffles are best enjoyed right off the iron for maximum crispiness. Serve them immediately with your favorite toppings.
