If you love your liver with potato, then cube the potato before you start and deep fry them until crispy. When the liver is cooked, add in the potatoes and stir only for 30 seconds - you want the potatoes to take in the masala of the liver but not get overcooked as you want them to retain the crunch.
Fry an egg sunny side up and serve it on top of the Kaleji just before serving
Slice some pav and put some of the liver (and potato if you like) inside. Add some kachubar as well to give it a tangy bite. Serve as an open sandwich or Mumbai-style as a meaty vada pav.
If you are a true blue Parsi you will do all three and add in both the potato as well as the eggs and then have it with the bread - take your pick.
