Why is my batter sliding off the hot dogs?
Usually it is one of three things: the hot dogs are wet, the batter is too thin, or the oil is not hot enough. Pat the hot dogs dry, dust with flour, and aim for a batter that is thick like pancake batter. It should coat the hot dog and not immediately run off. Fry at 350°F.
Quick fixes: If the batter is runny, whisk in 1 tablespoon flour at a time. If it is so thick you cannot dip, add 1 tablespoon milk at a time.
Do I need cornmeal, or can I use all flour?
Cornmeal is the whole point of the classic flavor and texture. If you go all flour, you get more of a fried pancake vibe. Still tasty, just not traditional.
What oil is best for frying corn dogs?
Use a neutral, high smoke point oil like canola, vegetable, peanut, or avocado oil. Save olive oil for salad dressing.
Can I make the batter ahead of time?
You can mix the dry ingredients ahead. Once you add the wet ingredients, use the batter within about 30 minutes for the best lift. If it thickens as it sits, add a splash of milk and whisk.
How do I know the oil temperature without a thermometer?
A thermometer is best. If you do not have one, drop a tiny bit of batter into the oil. It should sizzle immediately and float, then slowly turn golden. If it browns too fast, your oil is too hot. If it sinks and barely bubbles, it is too cool.
