Upma

Almost all south-indian restaurants serve this upma. There are many udipi restaurants in Matunga(central) area. Just to name the few are... Sharada bhavan, Amba bhavan, Ramashraya, Udipi, Mysore Cafe..... Udipi Shrikrishna and Mahabhoj are also located in the same area  but they only serve full meals.
The upma that I make and that from the restaurant are different in taste though the ingredients are same. I think the difference is I use roasted rawa and they don't ( or the time for roasting varies)
I have not tried the upma with plain semolina(non-roasted) as my children like the way I make it....:)

Ingredients
1 cup jada rawa/semolina
1/4 cup green peas(optional)
2 and1/2 cup of hot water
salt and sugar to taste

Tempering
2 tsp oil /ghee (tastes better in ghee)
1/2 tsp mustard seeds
1/2 tsp chana dal
1/2 tsp udad dal
4-5 cashew nuts
1 tsp asafoetida
5-6 curry leaves
2-3 chopped dry red chilies(halved)/green chilies (chopped)

Garnishing
Freshly grated coconut
Chopped coriander leaves
lemon juice

Method

1.Heat the oil/ghee in the pan.
2.Add all the ingredients of tempering.
3.Add green peas.
4.Add semolina. Roast well for 5-7 minutes.
5.Add boiled water (you can add salt and sugar while boiling)Cover the pan.Let it cook for 3-5 minutes or till all the water gets soaked
6.Squeeze in the lemon.
7. Garnish with coconut and coriander and serve.

Note
My mom used to keep pre-roasted rawa handy. (that served two purposes...1. It saved her time by 5-7 minutes and 2. increased the shelf life of rawa.
Nowadays refrigerating it is another option.
