Where do you keep your food?

Pantry if you can walk into it, cupboard if you can't (Australia).

'Larder' sounds very British. I don't think you could say the word in Australia without putting on an English accent.

Maybe 'larder' was less used because all those non-rhotic accented people confused it with 'ladder'?

An ngram of pantry and larder is interesting - for people who find such things interesting.

It's still used by non-rhotic speakers in England and because the vowels are so different there's no confusion. Even if they were homophones, context would make it clear. (Apologies if you were joking and I've taken your comment too seriously!)

NZ and for me: I would use a pantry and a cupboard to mean the same thing. I would say all pantries are cupboards (incl walk in cupboards) but not all cupboards are pantries. For example, I would keep food in a pantry but I might also call it a pantry. I keep plates & cups in a kitchen cupboard but I wouldn't store them in a pantry. Although i just looked at what wiki said and apparently a butlers pantry would keep those items.

I think larder is more unusual but I'm not sure if that's because it's simply not used, if it was used for a different purpose or even if it's a regional variation and I just am not aware of it.

No, it would sound like the car. Pantry is in use here (Scotland) to describe a walk-in household food cupboard. "Larder" is a bit more abstract, most often used for food store in general but not a specific place. Like in the TV show "Scotland's Larder", or this link

Rats, my proofing skills have failed me again.

I absolutely have to start using emoticons!

I think pantry is still in common use in NZ and Aus. It's an extra large full height cupboard for food storage, yes a cupboard but def. called a pantry or sometimes a pantry cupboard! In older homes, as already described, it was a seperate room. Some new homes, large ones, will have a 'butlers pantry' which is basically the same thing. Re. the fridge reminiscing, my grandmother in NZ didn't have one, her old villa style house had a "safe", sometimes called a meat safe, once very common. It was a shelved box built into the kitchen wall so it stuck outside, to catch the breezes, and had mesh walls to keep the flies etc. out. We had a portable tin version we took camping.

ooh yeah my grandmother had one of those. Or at least, a cool cupboard type thing. She's always had a fridge in the house since she moved into it but the house was also built with that cool cupboard. Even now she finds that she prefers to keep some food cool - but not cold - in that box.
