If you want to get long sprouts leave it for longer then you get longer sprouts.
The sprouts should be steamed for short time only so that colour and nutrients are intact.
I have not added lemon juice if you want you can add and for more spiciness you can add some chopped green chillies.
The ingredients added can be anything that will go with the salad it may be some chopped cucumber some pomegranate or even boiled potatoes.
