In a large bowl, whisk together flour, baking powder, baking soda, and salt.

Add the sourdough discard, milk, eggs, honey, and melted butter to the dry ingredients.

Stir together until mixed (batter will still be lumpy — that’s okay!)

Ladle batter onto a buttered waffle iron (or onto a griddle if you want to make pancakes).

Continue with step 4 until all the batter is used.
