Trim the edges of radish and carrot and peel the skin. Chop them into chunks and pressure cook in an Instant Pot for one minute. When the cooking is complete, quickly release the pressure and take the veggies out.
Let it cool, and chop the veggies into small cubes. VVK Tip: I love to chop veggies like beets, turnips, carrots, and radishes after steaming. It makes it very easy. If you are using a stove-top pressure cooker, you can pressure cook for one whistle and let the pressure release quickly. You can also microwave the veggies. Fill a microwave-safe bowl with water and add the veggies. Cook for 7 to 8 minutes. This timing differs based on your microwave power setting.
Heat the kadai and add oil. Once the oil is hot, add mustard seeds, urad dal, and channa dal. When they start spluttering, add dried red chilies, curry leaves, and asafoetida. Fry them for a minute.
Add the boiled veggies and salt.
Mix them well; once the water(if any) is all evaporated, add the coconut and almond flour.
Let it cook for a couple of minutes on low heat, and that is, the poriyal is ready. Garnish with cilantro and enjoy.
Notes
If you want to skip steaming in a pressure cooker, after the tempering part, you can add the chopped veggies and salt and about ¼ cup of water. Cover and cook till they become tender.
Adjust the salt and spices according to your preference.
