How To Make Sourdough Batter

Creating a batter from your sourdough starter or sourdough discard is so easy! You literally just need to thin it out a little and add some extra "puff" and you're away!

  1. Slice your meat or vegetables into small pieces - you can cut them however you'd like to eat them. Just don't make them too thick or they will not cook properly in the oil. Set aside until you're ready to cook them (you can see how I've sliced my chicken and vegetables in the photos).
  2. Take your sourdough discard, add it to a bowl along with the baking powder and a little of the seltzer water. Use a fork or whisk to thin the discard out until it's like a thin pancake batter. You don't want it too thick. Remember it's better to add it little by little to ensure you don't add too much water.
  3. Heat the oil you're going to use for frying (you want it between 350F and 375F or 176C and 190C) - see notes in post above for options on pans and oils.
  4. When you're ready to fry your meat or vegetables, lightly dust each piece in all purpose flour so they are lightly coated and then dip them into the batter.I do it in batches, so I do a quarter of the pieces of food into the flour and then throw them into the batter.
  5. Very carefully transfer the vegetables or meat pieces from the batter and into the hot oil.
  6. Use a scoop to ensure that they are frying evenly and turn them after a minute. They will rise to the top and then go a golden brown. They take around 3 - 5 minutes to cook, depending on the type of oil you're using and the temp you're frying at.
  7. Remove the meat or vegetables from the hot oil once they're golden brown using a metal scoop. Pop them on some paper towel to drain before serving.
  8. Sprinkle with salt if desired.

Have everything laid out ready to go when you're ready to start frying - it will make things much easier and cleaner when you're ready to start frying.

Tips for Using Sourdough Discard Batter

Oil - If you do not have vegetable oil you can fry  in canola oil, rice bran oil, peanut oil or grapeseed oil. You want a light flavored oil that won't add too much flavor to the food you're frying. Do not over batter the pieces or you risk making them soggy.

Cooking Temperature - The temperature of the oil is really important for the best result. Too cool and the batter will be greasy, too hot and it will burn. 

Seltzer Water - I use seltzer water that I make using my soda stream - but you can use any store bought carbonated water (it could be called sparkling mineral water, soda water or carbonated water depending on where you live).

Beer - You can use beer instead of seltzer water if you wish, this will add more color and flavor to your batter. I love using beer when we are frying fish in this sourdough discard batter.

    We did this sourdough discard batter with 5 lbs. of cod, fantastic. I also did use a light beer in lieu of the seltzer water, family said it was the best they have tasted, light yet crispy, without overpowering due to oil retention.
