Basically the bars are formed in a pan like rice crispy treats and the Laddu are balls formed of the same mixture. Mamra is puffed rice with just a touch of salt from India. I found it in a great new market and am finding new recipes to use it. If you use Rice Crispies add just a little salt. It will not be the same, but should work well. With peanuts added it tastes like a crunchy PayDay or Peanut Bar. Variations: Peanuts, cashews, roasted edamame, pretzels, rice crackers, wasabi peas, coconut, raisins, almonds, pecans etc etc.
