Note: This recipe is all about toasting different spices and lentils of varying thickness. The rule of thumb is that the thinner or more delicate spices are toasted for a shorter period of time and the thicker lentils are toasted for a longer period of time. It is important to really take the time to get a nice toast on each ingredient to really get a deep and nutty taste!
In a medium pan, on medium-low heat dry roast 7-10 whole dried red guntur or chili de arbol. Constantly move the chilis so they don't burn. You are looking for the chilis to dry further and warm enough to release their essential oils. This should take ~3-4 minutes. Remove the chilis from heat and allow to cool in a small bowl. A good indicator that the chilis were toasted properly is that they will snap when broken in half. If they are soft when you bend the chilis, that is an indicator that they need to be toasted longer.
Add the 20 curry leaves to the pan and toast until the curry leaves dry and crisp. It should be fairly quick and take between 1-2 minutes if that. The curry leaves should be crunchy and brittle when cooled. Transfer the curry leaves to a separate small bowl from the chilis.
Turn up the heat to medium. Add ¼ cup split urad dal and dry roast until the urad dal gets golden. It should take ~4-5 minutes for this to happen. Transfer the urad dal to the bowl with the curry leaves.
Turn up the heat to medium-high. Add 2 tablespoons chana dal to the medium pan and dry roast until the chana dal is golden brown. Turn off the heat. Be patient as the chana dal is thicker and will take 5-6 minutes to really toast and turn golden brown. Transfer the chana dal to the same bowl as the urad dal.
Allow all the spices to cool for 5-10 minutes. This is important as warm spices will create condensation when ground and therefore reduce the shelf life of the milagai podi.
In a spice grinder, first add the dried chilis. It helps to snap the chilis into smaller pieces to help the grinder blend. If the grinder is too full, grind the chilis in batches to ensure there is enough space in the grinder. Grind the dried chilis until they are a fine powder. Try to get the chilis as fine as your grinder will allow. Tap the spice grinder lid to push the spices into the grinder when opening it, to prevent powder from flying around and being wasted. When opening the spice grinder, do not directly smell the powder as the chilis can irritate your nose. Empty the chili powder back into the small bowl.
Add the toasted and cooled chana dal, urad dal, and curry leaves into the spice grinder. You may need to grind these ingredients in batches depending on the capacity of your spice grinder. Pulse the grinder to get a coarse powder that has pieces that are not fine but not too big that it would hurt to bite through. The coarse bits of urad dal and chana dal add a crunchy element to the podi that makes it taste so delicious.
Mix together the fine chili powder, coarse dal and curry leaf powder, 1 teaspoon asafetida, and ¼ teaspoon fine sea salt. The milagai podi is now ready.
When tasting the milagai podi, do not eat on its on as it is very spicy. Milagai podi is best eaten when mixed with warmed ghee to create a condiment to dip idlis and dosas into. The ghee helps temper the milagai podi and add a buttery/nutty element to balance the heat. This podi is also a great seasoning to add on top of crunchy roasted potatoes!
