If you've ever read a menu at a Persian restaurant, you probably would have seen kashk-e bademjan, a delicious eggplant dip, topped with kashk, a by-product of cheesemaking that's strained and dried to varying degrees. The result is a thick concentrate milk solids that carry a distinctive smell and can be sold in anything from jars of paste to dried balls that get rehydrated before use.
Use this ingredient as a topping where you would use a creamy feta or a strong, salty yoghurt. You can even try using it to thicken a hearty winter soup, like this Persian ash-e-reshteh, filled with vegetables, noodles and beans, or add it to your favourite baba ganouj recipe for a creamy twist.
So, how did our judges do in the blind taste test?

Have the TCL judges ever tasted this fermented dairy product? Source: The Chefs' Line
[Dan] I know!
[Melissa] It's on the tip of my tongue, but I can't...
[Dan] I've got it...I think.

What will their final guess be? Source: The Chefs Line
[Melissa] I don't know!!
(It's kashk. A Middle Eastern fermented whey.)

Our chefs take their best guesses... Source: The Chefs' Line
[Melissa] Ahhhhhh.
[Dan] Ah okay. And what animal?
(Cow)
[Dan] Really? Damn, I wrote goat's cheese.
(What sort of flavours did you get eating it?)

[Mark] It was sour.
[Dan] It was like a cheese spread.
[Melissa] Yeah it was kinda like that parmesan-y, umami...
[Dan] I got that goat's feta...
[Melissa] Yeah I would've said goat or sheep.
[Mark] Sheep, definitely sheep.
[Melissa] Kinda like in-between parmesan and you know that cheese that's parmesan-but-not-parmesan-that's-not-refrigerated? That stuff.
