In a bowl, mix together the instant mashed potato flakes, flour, and a pinch of salt.
In a separate bowl, whisk the water and egg until well combined.
Pour the water and egg mixture into the dry ingredients and stir until a dough begins to form.
Knead the dough gently for a short time, then roll it into logs and cut them into small pieces.
Shape the gnocchi as you like, either by using a fork or by cutting them into squares.
Bring a pot of water to a boil and cook the gnocchi for about two minutes, or until they rise to the surface.
To make the sauce, melt butter in a pan until it turns a golden brown color, then add the capers.
Toss the cooked gnocchi in the brown butter and caper sauce before serving.
