Add all the ingredients except oil/butter in a bowl, whisk them well to form a smooth batter. Let it rest for 30 minutes. The batter can also be refrigerated in an airtight container overnight.
When ready to cook, preheat a waffle maker & brush it with oil / butter.
Use a ladle to pour the batter in to just cover the plates. Close the waffle pan.
Cook the waffles for 5-6 minutes until they turn golden in color & crisp. The time to cook might vary slightly depending on the make of the waffle maker. Resist from opening the waffle maker to check on the waffles before they are fully cooked. After multiple tests, we have found this to be approx 5 minutes across 2-3 different brands. Opening in between leads to the batter sticking on top and bottom.
Once cooked, put them on a rack to avoid them turning soggy before serving.
