Here is how  you make plain MEDHU VADAI  using simple cumin & pepper.

Soak urad dal in enough water for atleast 3 hours… Grind to a fluffy conistency using green chilli , ginger and salt using very little water.

Check my Onion  Medhu Vadai post  to make vadais. You may use leftover vadai to make this… and thats how this dish originated 🙂 Adding onions is optional…

Add in spicy variety of chillies and some ginger while grinding.  Add in salt too while grinding to yield a good texture. Using kallu uppu / edible rock salt / crystal salt does make a difference.

Add very little water while grinding. iam using a wet grinder… if using regular mixer mate, then use ice cold water to grind.

The vadai batter should look fluffy like an angel… it should float when dropped in water.

Add in coriander or onion if you like and shape them. Check all our VADAI RECIPES here.

Fry them over medium high flame … make sure not to brown too much.

Once done remove and cool completely before adding to the warm milk. Caution: Adding hot vadai to hot milk or water will make them loosen too much and break apart. 

Soak them in warm water  or warm milk… my aunt use to soak them in dilute mor / buttermilk that way it drinks up the liquid as well the curd flavor. Try our BREAD VADAI by  Mrs.Priya

Here is another version of THAYIR VADAI by Mrs. Kalpana Murali

Then temper the curd with all the spices and soak the vadai in curd mix for 30 minutes. Decoration is optional… it taste good plain with light tempering… serve chilled or at room temperature.

Use all the topping only before serving.. to keep it crunchy!

Notes

• Warm Milk works for soaking. Same way warm water woks too. I have seen my aunts saoking these vadai in light buttermilk first for few minutes and then add it to the curd mix.
• Do not add hot vadai to curd mix. Do not soak vadai in hot water or warm water… it will loose its shape.
