Pour boiling water over the ground saffron, cover with a saucer, and set it aside.
Alternatively, place an ice cube on top and let it stand until it has melted. Shake occasionally to combine saffron and ice.
Add the minced meat and fry until crumbly.
Mix in the Advieh Polo, or the spice mix, turmeric, salt, and pepper.
Add the green beans, 2 tablespoons of saffron essence, 300ml of water and lemon juice.
Cover the bottom of a non-stick pot or a rice-cooker with ghee or oil, then add 2-3 tablespoons of saffron essence and mix well.
Wrap the lid of the pot with a clean tea towel and place it firmly on the pot to prevent condensation from dripping into the rice. (This step is not necessary with the Reishunger rice-cooker.)
Steam the rice cakes over very low heat for 30 to 45 minutes until the rice is fully cooked and the flavors are well infused. Do not open the lid in the meantime.
Loobia polo is traditionally served with a shirazi salad, natural yogurt, mast-o khiyar, or pickled vegetables (torshi) or sir torshi.
