A couple of days ago I put some left over madras and vindaloo, which I had cooked, in bowls covered in foil for storage in the fridge. The next day, there were holes in the foil where it had touched the curry and flakes of foil in the food. I normally use plastic wrap and will make sure I have some in the house for next time.

In the meantime, has anyone else experienced this? Could it be due to the lemon juice that I put in the two curries?

Any thoughts appreciated..

I used to store my gravy in ali takeaway containers. I discovered that the gravy had started to eat away at the bottom producing tiny pin holes .  Mind you, it had been in there for quite some time.  I now use plastic food bags   I'll give the foil a miss then when it comes to covering curry then  :

Yes I won't be using it again. I wonder if this is why Indian T-A's are increasingly served in plastic as opposed to the old alu containers?
