Here's how you do it. Start with about a cup of dry milk powder and about 1/2 cup flour. Add a teaspoon of baking soda. Then mix your dry ingredients. Add a little melted butter and wet the whole mixture with milk until it comes together. You should be able to roll it into balls. You can always adjust a little bit here and there. Fry it up :)
Make some simple syrup infused with cardamom seeds. Pour over the gulab jamun while warm.
