Ginger Yogurt (Allam Perugu) chutney

The other day when we were at my cousin's place, she prepared this chutney, which goes well with either utappam or with paratha's also. It was quick to make, good for your tummy and yummy to eat. So here goes the recipe from her:

Ingredients
Ginger - small piece (grate it or smash it in mortar)
Yogurt - desired quantity (probably 1 cup)
Salt to taste - (1/2 tea spoon)
Lemon juice - 1/2 tea spoon

Method of preparation
Mix all the ingredients well and serve it cool with either hot utappam or paratha.
