Bring on breakfast with this best buttermilk waffle recipe.
Place cooling rack in rimmed baking sheet. Adjust oven rack to middle position and place baking sheet in oven. Heat oven to 200 degrees. Heat waffle iron.
In large bowl, whisk together flour, cornmeal (if using), baking soda, and salt. In medium bowl, whisk together buttermilk, eggs, and melted butter.
Add buttermilk mixture to flour mixture and use rubber spatula to stir until just combined and no dry flour remains. Add cheddar, scallions, and crumbled bacon and stir gently until just combined.
When waffle iron is hot, spray lightly with vegetable oil spray. Use dry measuring cups and rubber spatula to scoop batter and scrape into middle of waffle iron (use about ¾ cup batter for 7‐inch round waffle iron or about 1½ cups batter for 9‐inch square waffle iron). Spread batter into even layer. Close waffle iron and cook until waffle is golden brown.
Mix and match different ingredients to make these waffles just the way you like them. In place of bacon, cheddar cheese, and scallions, try:
Meats: ¼ cup crumbled cooked breakfast or lap cheong sausage; finely chopped cured Spanish-style chorizo or deli ham
Vegetables and Herbs: 2 tablespoons finely chopped onion; 2 teaspoons minced fresh thyme, rosemary, or parsley
Cheeses: 1 cup shredded Monterey Jack, pepper Jack, Colby, or Gruyère; ½ cup finely grated Parmesan cheese
Other Flavors: 1 seeded and minced fresh chile; 1 cup drained and chopped cabbage kimchi; 1 teaspoon chili oil
Buttermilk, a slightly sour ingredient, gives these savory waffles their light, fluffy interiors. Acidic buttermilk reacts with baking soda to produce carbon dioxide gas, creating bubbles in batter. When the butter solidifies in the hot waffle iron, some of the bubbles are trapped inside, creating these waffles' airy texture. Traditionally, buttermilk is made from the liquid leftover after churning cream into butter, but today most of the buttermilk you find at the grocery store is cultured buttermilk, made from milk that’s been fermented using bacteria.
