Thechwani is a rustic curry from Uttarakhand, made using smashed potatoes and/or radishes. Try out my version of potato-black eyed peas, prepared Thechwani style!
You can omit the black eyed peas and make this curry with just potatoes, or radish or a mix of radish and potatoes. Smash the radish, with a mortar-pestle, just like you would, the potatoes. If you don't like the taste of mustard oil, use regular neutral flavoured cooking oil.
