Prep the Rice: Take your leftover cooked rice in a large bowl and gently fluff it with a fork or your fingers. Ensure there are no large lumps so the tempering coats every grain evenly.
Roast the Peanuts: Heat 2 tablespoons of groundnut oil in a pan or kadai over medium heat. Add the peanuts and fry them until they turn golden brown and aromatic. Remove the roasted peanuts from the oil and keep them aside in a small bowl to maintain their crunch.
The Tempering: In the same hot oil, add the mustard seeds. Once they start spluttering, add the channa dal. Sauté for a few seconds until the dal turns light golden.
Infuse Aromatics: Add the broken red chilies, curry leaves, and a pinch of hing. Stir for 10 seconds until the leaves are crisp and the chilies change color slightly.
Add Color: Lower the heat and add the turmeric powder. Stir quickly for 2-3 seconds, be careful not to burn the turmeric, as it can turn bitter.
Incorporate Rice: Immediately add the fluffed leftover rice to the pan. Mix gently but thoroughly using a spatula until the rice is completely coated in the yellow tempering.
The Lemon Finish: Turn off the heat. This is important to prevent the lemon juice from turning bitter. Squeeze half a fresh lemon over the rice and add salt to taste.
Final Toss: Add the roasted peanuts back into the pan. Give it one final gentle mix and serve your vibrant Elumichai Sadam warm.
