This is usually made on Sri Rama Navami.
Jaggery, Black pepper, water
Mix jaggery with cold water. It takes time to dissolve. After the jaggery completely dissolves, filter the water. Then add some finely powdered black pepper. I prefer to grind the pepper myself instead of store bought pepper powder. This gives a very nice flavor.
When you taste it, you should be able to taste the sweetness of jaggery and the spice from the pepper.
