I’ve never had the fluffy Japanese pancakes and found one basic recipe that includes pancake mix. Now I’m googling pancake batter recipes which call for flour, sugar, baking powder, and salt for the mix. Only one recipe (kitchn) suggests waiting 10 minutes after mixing all ingredients to allow for the baking powder to kick in - does that 10 minutes make an impact? I have the time and am intrigued that the other recipes include baking powder but don’t mention any delay.
