Rice and Lentils
- 2 cups Basmati rice
- 1 cup green lentils (or brown lentils)
- 2 teaspoons ground cinnamon
- 2 tablespoons kosher salt
- 1/2 teaspoon ground saffron (from saffron threads)
- 1/3 cup water (for blooming saffron)
Vegetables and Flavorings
- 1/4 cup extra virgin olive oil
- 2 yellow onions, finely sliced
- 1 cup raisins
- 8 Medjool dates, pitted and quartered
- 2 tablespoons neutral oil (vegetable oil recommended)
- Rinse and soak the rice: Rinse the basmati rice under cold water until the water runs clear. Place in a bowl, cover with cold water about two inches above the rice, and soak for at least 30 minutes or overnight for best results. Drain before cooking.
- Bloom the saffron: Grind saffron threads into a fine powder using a mortar and pestle or spice grinder. Combine the ground saffron with 1/3 cup water in a small bowl and set aside to bloom, releasing its color and aroma.
- Cook the lentils: Place lentils in a medium saucepan, cover with water two inches above, and bring to a boil over medium-high heat. Simmer until lentils are tender on the outside but still slightly firm in the center, about 20 minutes. Drain using a fine mesh strainer.
- Season the lentils: Return drained lentils to the pan off the heat. Stir in the ground cinnamon and 1 tablespoon of extra virgin olive oil until combined. Set aside.
- Prepare the onions: Heat a large cast iron skillet over medium-high heat and add the remaining 3 tablespoons of olive oil. When shimmering, add the sliced onions and sauté, stirring regularly, until golden and crisp, about 20 minutes. Adjust heat as needed to prevent burning. Using a slotted spoon, transfer onions to a paper towel-lined plate to drain.
- Season the raisins: In the same skillet, reduce heat to low and add raisins. Stir for about 1 minute, coating them in the onion-flavored oil. Transfer raisins to a bowl and set aside.
- Parboil the rice: In a large non-stick pot, bring 8 cups of water with 2 tablespoons kosher salt to a boil over high heat. Add soaked and drained rice and cook 5 to 7 minutes until slightly softened but still firm. Drain rice through a fine mesh strainer and stir into the cinnamon-spiced lentils mixture. Rinse the pot and return it to the stove.
- Prepare the tahdig layer: In a medium bowl, combine 1 cup of the cooked rice and lentil mixture with 1 tablespoon of the bloomed saffron water. Gently stir until the rice turns a golden yellow color.
- Crisp the tahdig layer: Pour 2 tablespoons of the neutral (vegetable) oil into the pot. Without turning on the heat, add the saffron-infused rice and lentil mixture and gently press it into an even layer using the back of a spoon.
- Layer the rice: Add the remaining rice and lentil mixture on top without pressing down. Scatter the caramelized onions, then the raisins, dates, and drizzle the remaining saffron water over the top. Use a spoon to poke five evenly spaced holes through the rice, reaching the bottom of the pot to allow steam circulation.
- Steam the rice: Cover the pot with a lid and bring heat to high until steam starts to rise. Reduce the heat to low and continue steaming for 1 hour, ideally wrapping a clean tea towel around the lid to absorb moisture and prevent condensation dripping. Monitor closely to avoid burning the tahdig.
- Serve the rice: Remove the lid and gently fluff the rice to mix the layers. Use a spatula to carefully lift the crispy tahdig (bottom crust) from the pot, either serving it whole or broken into pieces alongside the rice in the serving dish.
Notes
- For best flavor and texture, soak the rice overnight instead of the minimum 30 minutes.
- Use a heavy-bottomed pot or cast iron to ensure even cooking and prevent burning the tahdig.
- The tahdig layer is the prized crispy crust at the bottom; avoid stirring vigorously to keep it intact.
- Blooming saffron is essential to unlock its full flavor and vibrant color.
- You can substitute green lentils with brown lentils if preferred.
- Adjust cinnamon quantity based on personal taste for spiciness.
