Everyone loves this potato curry.
Take three or four large whole potatoes and simmer gently in salted water until they are just cooked through. Peel and cut into about 1" cubes.
In a large saucepan (a Wok is ideal) put about 3 teaspoons of black mustard seeds and about two tablespoons of vegetable oil. Gently raise the heat until the mustard seeds pop. Be careful not to burn them.
Add one large finely chopped onion and cook until it starts to brown. Add a couple of crushed garlic cloves.
Then add the spices: 1 desert spoon of good curry powder and about a teaspoon of garam masala (adjust to taste).
When the spices release their aroma add the potatoes. Carefully turn and mix the potatoes until they are covered with the spice mix and onions. Salt to taste (I like lots!).
It can be eaten hot or cold, as a side dish or as a main.
In fact, its so versatile we even had it as a side dish with my wife's thanksgiving turkey. Heresy you say?
Possibly, but very nice heresy
