Add sugar only after rice is thorougly cooked.
Mawa can be either store-bought or home-made. Though making Mawa at home is a tedious affair, that home-made taste is often compromised in the store-bought ones. If you have the time and patience, go for it. Here are some super easy ways to make your own using evaporated milk and dry milk powder.
Mawa is usually available in world food markets or Indian grocery stores in frozen form.
Add only just enough saffron as mentioned to add a touch of color to Payesh so that saffron aroma stays from clashing with that of rose.
If using rose essence, add a few drops and check first and adjust accordingly. Do not add all at once as essence is much stronger than rose-water. Pure rose-water is simply the distilled water of roses.
I have used CORTAS rose-water with ingredients listed as only distilled rose-water.
Rose essence however almost always comes with some kind of alcohol along with the rose oil.
As mawa is rich by itself, I have used non-fat milk. However, go for 2% milk or even whole milk if you are looking for a richer and creamier Payesh.
If you want to make this recipe healthier, substituting white basmati with brown basmati rice would be a good start.
Don't
Add rose-water to hot payesh or the rose aroma evaporates due to the heat.
Skip setting the strained rice aside for 30 mins. It is essential for the basmati rice to cook well.
