Heat a thick bottomed skillet or frying pan or kadai (wok). Keep the heat to low or medium and add the raw dried peanuts.
Stirring at intervals begin to roast the peanuts.
Keep on roasting till the peanuts become crunchy. The peanuts should not have even a bit of rawness in them. They should be roasted very well.
Just cool and taste a few peanuts. You should not feel even a bit of hardness or rawness while eating them. If you get the raw taste, then continue to roast for some more minutes. You can also opt to roast the peanuts in an oven.
Once the peanuts are roasted well, keep the pan on the kitchen countertop. Let the peanuts cool at room temperature.
When the peanuts are completely cooled, rub the peanuts between your palms, so that their skin peels off. Do this with all the peanuts. This part of peeling peanuts takes some time.
Making peanut ladoo mixture
Now add the peanuts in a grinder jar.
Add jaggery powder or grated jaggery.
Run the mixie or grinder for a few seconds and then stop. Check the texture of the ground peanuts. Continue again for few seconds and stop. Grind till you get a coarse consistency in the peanuts.
You can also use the pulse option in your mixer-grinder. You have to grind in parts till a bit of oil releases from the peanuts. Take a small portion of the mixture in your hands and then press. It should hold shape and not crumble.
Don't grind at one stretch or grind too much as then much oil will be released from the peanuts and you will get peanut butter.
Take the ladoo mixture in a plate or tray.
Making peanut laddu
Now take a small portion of the ladoo mixture in your palms and begin to shape it into peanut ladoos.
Make ladoos with the rest of the mixture.
This recipe yields 10 to 12 ladoos. The recipe can be easily doubled or tripled. Store the peanuts ladoos in an airtight jar.
If living in a warm or humid place, then keep the jar in the fridge. If living in a cool or cold climate, then you can keep at room temperature.
Serve these healthy peanut ladoo plain as a sweet snack.
Before beginning with the recipe, check the smell and taste of peanuts. They should not smell moldy and taste sour or bitter. This means that the nuts have become rancid. So do not use these peanuts at all and trash them.
