Twizzlers. I like that it has a good chew. A lot of people recommend me different kinds of licorice or say that twizzlers aren't real licorice, but it's not the flavor that I like. I don't really care for the flavor of twizzler to be honest. I just like the consistency when I'm chewing on it.
Baked tofu. It's the blandest substance in the known universe, but it's cripsy and chewy and dense, and your brain is just like fuckyeah, protein.
Yes you can season the outside of it, but that's true for literally any substance. Hey, if you put barbecue sauce on carpet, it becomes barbecue flavour. No kidding.
Chicharron bulaklak. It's deep fried intestinal fat or something like that. Ok it doesn't sound too appetizing but when it's fresh it's so nice and crispy and melts in your mouth. Dip it in the vinegar to balance the oiliness and the texture+flavor combination is just amazing. Your arteries will hate you, but that's ok every now and then.
I think tripas used in tacos is typically from small intestine whereas the tripe in pho is from the stomach. That said, when done right the texture of both are quite unique and pretty damn awesome. Undercooked or overcooked tripas though... yikes!
Rock candy. I love how the crystals separate along flat planes as you chew. Don't get me wrong, the sugar is nice too, but mostly it's the texture experience for me.
Anything creamy and "fluffy": cheesecake, tiramisu, pastry cream, even pudding with whipped cream folded in (like in ambrosia salad). Cream puffs are especially nice, having that soft filling inside a pastry, mmm...
I've been buying these "Coco rolls" snacks recently. They're a crunchy flaky slightly sweet snack and I just can't get enough of the texture of them. They taste good too, but it's the texture that I crave.
Dragee stuff. Like sweets with a hard coating and a softer inside (dragee eggs). When you break the coating the whole thing starts to melt in your mouth.
One thing I love and simply haven't found a replacement yet: "Obstgarten" yogurt which is very fluffy quark with a bit of fruit jam underneath. I don't want the fruit jam, but I do love the quark part. If you buy other quark products they simply don't have the same texture (which is probably created with nitrogen in an industrial process and can't easily be replicated at home).
