These are Turkish Doritos, and the flavour is called TURKISH. A marketing masterclass is in play here.
The flavour is subtle but nice - poppy seeds are infused into the corn chip unlike those seeded bagels you get where the poppy do a mass emigration as soon as your gnashers sink in. I do like the flavour of poppy seeds.
The tomato flavouring is sweet and subtle but it works quite well. Normally Doritos flavours are quite on the extreme side so dipping into these expecting that same extremity will leave you disappointed but as they are i'm pretty happy with this interesting variety on a Dorito. the fact they corners are slightly more rounded than normal clearly make no difference - but maybe help when accompanying with the right dip?
