What ingredient do you find in gluten?

Gluten is actually a protein, not a single ingredient. It's a combination of two proteins found in wheat, rye, and barley:

* Glutenin: This protein gives dough its elasticity and allows it to rise.

* Gliadin: This protein provides the stickiness and strength to the dough.

So, while gluten itself isn't an ingredient, it is formed by the combination of glutenin and gliadin found in certain grains.
