Add some water as you do not want the beetroot to burn.
Once the beetroots are cooked to your satisfaction add salt.
Let it sit covered for some time.
Just before serving add the sesame seeds and lemon juice.
Notes
n case you grate the peeled beetroot then you just need to add the grated beetroot to the tempering, stir. Close the lid and switch off the gas. Let it sit for about 5 minutes before opening the pan.
