How are Grofers in-house items

Bad

Their pulses and dry fruits are good, ghee isnt upto the mark

As per my experience grofers own brand items are not so good.
But you can try brand “family farm” specially pulses which I think are good in quality as per price.
Family farm is also their brand I think.

Mustard oil, sunflower oil are good. Ketchup is good, kadak tea is very good. Washing machine powder is good. Sonamasuri rice is good.
Detergent soap really bad. Family farm pulses are good. Family farm besan is really bad, not pure mixed with something.That is why besan I prefer freshly grinded from chana dal or Tata sampann.
Mother’s choice ghee ok, pickle good.
Mother’s choice pulses are also good. Some masala are good. Garam masala not upto the standard.
Some biscuits like wheat and coconut ones are really bad. No taste. Masala peanut is also bad.
Grofers rose syrup is also good. Using it to make rose lassi, comparable to rooh afza.
So only when you try you will know.
Ps: quality depends on local brands because they have tied with them only. So quality may differ state to state.
