Vegan Okonomiyaki with sourdough discard. I made this recipe because of my current project which is to make my own sourdough starter, hence this recipe is about okonomiyaki using a discard of my sourdough starter.

I hope I am not confusing you when I mentioned sourdough starter and discard. To give you a brief background and idea, a sourdough starter is a process of combining flour and water to make your own leaven which you will use in making your own bread and add flavor to your bread.

Now the discard is the part of your sourdough starter which you have to remove before feeding again your starter. The reason for removing the discard is to be able to maintain the same amount of flour and water you feed your starter because if not, you’ll end up feeding it more.
Having a sourdough starter is like having a pet that you need to check and feed especially on the first 5 to 7 days or up to 14 days depending on how warm or cold your area is and where you store your sourdough starter.
My sourdough starter is made of bread flour and water mixed together. The discard that I use for vegan okonomiyaki is from day 8 of my sourdough starter stored in a glass container which I keep inside the fridge. It is an unfed sourdough starter that can be kept for a few days in the fridge.
I only recommend to keep it for a few days or few weeks because since it is unfed it will also get hungry and therefore will create hooch ( a black liquid color) that you see on top of your discard which you can also remove but if not it will eventually have molds if totally neglected.
What is Okonomiyaki?
Okonomiyaki is a “Japanese savory pancake” that is made with flour based batter which is wheat flour. The word okonomi means “ what you like” while “yaki” means “grill” but here in this process, we’ll just fry.
There are two main styles of making Okonomiyaki. Osaka-Kansai style and Hiroshima although Okonomiyaki is widely available in Japan especially on the streets. And this makes me miss Osaka style Okonomiyaki.
Looking for a skillet try this cast iron skillet from Lodge
Osaka-Kansai Style Okonomiyaki – consists of flour, nagaimo (long type of yam), water, eggs, cabbage, onion, water, meat of your choice ( usually pork), seafood. The batter is mixed first then adding all ingredients and mix again before frying or grilling.
Hiroshima style Okonomiyaki – instead of mixing the ingredients it is cooked in a layering style and topped with yakisoba noodles. The ingredients are batter, cabbage, pork, with optional squid and prawn top with noodles (udon or yakisoba) and a fried egg. It is served with okonomiyaki sauce.
For now, I did the Osaka style Okonomiyaki pancake and soon will try Hiroshima style too.

But what if you only have leftover vegetables, then this recipe is for you. The good thing about okonomiyaki, it is very versatile that you can put in any vegetables you have and still enjoy this meal from Japan at the comfort of your home.
