Tomato chutney is very normal in all tamil families. In india we all use dry red chilli for chutney. It brings nice flavour to the chutney. But i live abroad. Here we dont get dry chilli frequently. so i tried it with red chilli powder it came out well.
salt as required
mustard seed- 1/2 sp
curry leaf - little
Put oil in the kadai, fry the onion nicely and add tomatoes and tamarind.
After the tomato get fried put chilli powder and salt
Nicely saute it, it will come to gravy consistency.
Remove the mixer from the kadai and keep it in other plate so that it will cool.
After it got cool. grind it in the mixie. while grinding add little water.
Again keep the kadai with oil to season, season it with mustard seeds and curry leaf and perungaya thool.
put the grinded chutney it the kadai and allow it to heat till the oil comes out or till it becomes thick
Serve it with hot idaly. Comes out very nice. I remeber my mother usualy bring this chutney while we go for picnic. Taste will be very good.
