West: Anglo Indian Curry Sauce

Directions

Heat oil in a heavy, medium-sized skillet over medium heat.

Add onions and stir-fry until onions turn caramel brown, about 12 to 15 minutes.

Remove from heat.

Place in a blender with the ginger, tomatoes, cilantro, cayenne and salt; purée until smooth.

Transfer to a medium-size saucepan.

Stir in garam masala or curry powder, cover, and cook over medium heat until tomatoes loose their raw aroma, 15 to 18 minutes.
