Wash the cowpea beans well and place into a pressure cooker.
Add the chopped pumpkin, pour water just till leveled, not too much. Add in the turmeric and red chilli powder along with salt.
Pressure cook for three whistles and then leave it on simmer for around 30 minutes. Switch off and allow the pressure to go by itself.
Meanwhile, grind all the “for grinding” ingredients till smooth.
Open the cooker lid, add in the ground ingredients and mix well. You will see that the pumpkin is all mashed up and coated over the cow pea beans.
Cook on low flame till just warm.
Heat up the oil in a little saucepan and splutter the mustard seeds. Pour it into mathanum payarum and mix well.
Serve as side for rice and any curry! I love to eat it as is…
