What does jianbing taste like?

Jianbing tastes sweet because of the sweet bean sauce but also savory thanks to the bacon and hot dog sausage. If I had to describe it, I'd say it's like a British bacon and egg breakfast but "Asianized".

Is this jianbing recipe traditional?

No, this recipe is not traditional. It is created with substitute ingredients since millet flour and mung bean flour can be difficult to find. The same goes for some Chinese sauces which can be hard to find. BUT don't worry, these crepes are still really delicious even without being traditional!

Can I Make Jianbing in advance?

Yes, you can prepare the batter in advance and keep it in the refrigerator. You can also fry the wonton crackers and leave them at room temperature. Then prep all your vegetables and keep them in airtight containers in the refrigerator. When you're ready to eat, cook the crepes and assemble the jianbing. I don't recommend making the entire jianbing and keeping it for the next day, the crepe will become harder (as it is made of flour and water only). Furthermore, the bacon and sausage need to be reheated while the lettuce and wonton cracker cannot be reheated. So the best is to assemble right before serving.
