Growing up in Goa this was my favorite tea time snack.
1. Add the rava into a pan and roast on low flame for approximately 3-5 minutes and set aside.
2. In a pan, add the water, ghee and sugar and stir continuously till all the sugar is dissolved. Add the food color and stir. Optionally, you could add elaichi powder (cardamom) for additional flavor. Now add the previously roasted rava and keep stirring on low flame.
3. Keep stirring the rava, till water disappears. When the Sheera is ready the rava grains are no longer be visible. Garnish the Sheera with cashewnuts.
