I have thing for curry in summer - I'm not sure why. It makes no sense to eat hot food in hot weather......
IMO there few things that go together as well a hot curry, a cold drink and a summer evening.
How hot?
My father use to tell me that something hot in hot weather is good for cooling you down...? cause it makes you sweat...not sure about the logics but he has lived in some hot places, so I guess he has some idea
DH loves a curry and cold larger anytime of year - and I do too (though I cant eat as hot as I used to since spending a few months in Bangladesh), but we`ll see if that still applies once we have our first summer in Australia

I usually keep some dried and tinned chickpeas too, but was hoping a slow cooker might be a easy/lazy way of doing the dried one.
