Chips Texture – How to Make Bubbles on the Surface of Chips?

enter image description hereI've never asked a question on here as i'm a new user, I was just wondering if someone could explain how to put bubbles into chips. Ours is a protein based chip and we had a batch that fried and had a lot of bubbles causing a different texture and more crunch but we are having troubles replicating that.

Admins you can delete this if it's not uniform enough.

We fry with Sunflower oil. The protein is mixed with tapioca starch and seasonings

The bubbles are formed by gases expanding inside the chip as it is heated.

Do this slow enough and the bubbles will escape before the chip hardens (giving it that chip crunch).

Do this fast enough and the bubbles will be trapped.

You could try higher heat for a shorter period of time - or even very high heat to "seal" in the bubbles then finish at a lower temperature.
