Signs Curd / Dahi (homemade) has gone bad
- Strongly sour, yeasty, or alcoholic smell beyond normal tang.
- Pink, grey, or black mold spots.
- Fizzy or bubbling surface from wild yeast.
Still good if
- A thin layer of watery whey on top — stir it back in or drain it off.
- Slightly more sour than fresh, but clean-smelling with no mold.
Discard immediately if
- Any coloured mold spots
- Fizzy or bubbling texture
- Sharp, acrid, or alcoholic smell
Why guidance varies
Homemade dahi has live cultures and no stabilisers, so its safe window depends on how warm the kitchen was while it set, how fast it was chilled, and fridge temperature. High Indian ambient temperatures cause faster souring and separation.
