What ingredient do you put in batter so it will stay crisp after cooking? Baking soda or corn starch
To make your batter stay crispy after cooking, add baking soda. It has soda particles that harden batter, making it crispy. However, you should be very careful to avoid confusing it with baking soda. For more information, visit www.bestrecipes.com.
Corn starch for sure! works in my Dutch oven cooking, might not work well in normal baking.
