Great! It’s one of those recipes that needs a few tweaks but worth it once you get it. Good luck!

Sounds like you overmixed it. Gluten causes it to act Ike that. Don’t use a mixer, hand knead it. You only need to knead it about 10 times. Also seems like your batter is too thick. I’d recommend a little bit more liquid. These should help.

Edit to add: YouTube is great for this as well so you can see what’s it’s supposed to look like.

Even when I lived in texas I made my own. I just google a recipe and follow it. The secret for me is letting the dough rest for 20-30 minutes. Helps with texture and flavor.
