Pods from an Indian store in Europe (UK or ?,I forget)
These were the only ones the person could find in a semi ripe condition to get seeds from,they are used/sold green.
Though they look the same they weren't..
Some were hot,others weren't.All were slightly different in some way from each other.
These were actually 14 different chile types - had different names/bins at the market.
I also got a couple birds eye types but cannot find the pic.
I'd guess you would have to go to a market that gets their pods only from India sources in India to get the real thing.
I'd bet the markets selling new mex or whatever varieties are only using a substitute pepper because it's easier to get or cheaper and still sells.
I've seen HUGE piles in pics of peppers drying in the sun in India that look similar to my pic.
Never seen anything other than pods that look like my pic or a birds eye sold in the Indian markets I've been to.
Well until Bhuts,Nagas etc. showed up and became popular.
