In a small bowl add the Saffron strings and the water. The Water will take out the orange red natural color from the saffron strings. Let the strings soak a little bit.
Add Sugar and Cardamom powder to the Greek EkoYogurt & mix well.
Continue to add to the yogurt mixture the Saffron strings with the colored red water. Also add in the crushed Pistachios and Almonds. Mix the whole content well.
Keep in the fridge to cool. Shrikhand has to be served cold.
