If you are not using leftover mashed potato, boil or steam the potatoes and mash them. It should be around 1 cup of mashed potatoes.
Finely chop mushrooms, walnuts, and cilantro leaves.
Heat a saucepan or skillet over medium heat and add a teaspoon of oil. Once it is hot, add chopped mushrooms.
On high heat, saute the mushrooms. Mushrooms will start releasing their water.
Let them cook till all the water gets evaporated and switch off the flame. It took around 8 minutes for me.
Now take a mixing bowl and add mashed potatoes, sauteed mushrooms, chopped cilantro leaves, walnuts, salt, ginger paste, garlic paste, and spice powders. I used puffed amaranth seeds for the crunch and binding.
Mix this potato mixture well and form a dough out of these. If you cannot make a dough, add more puffed amaranth.
Make small orange-sized balls out of the dough and shape them into patties.
Roll them over puffed amaranth so that these get coated well.
Take a pan and fry these over medium heat using little oil on both sides.
And the easy, delicious, and crispy mashed potato patties are ready to serve!
