Why is my dough so sticky?

Name: Gluten-Free Dairy-Free Puff Pastry (Lots of Flaky Layers!)
Prep time: 60 min
Cook time: 25 min
Total time: 205 min
Ingredients: 2 1/2 cups gluten free flour blend (* see notes!); 1/4 cup cane sugar; 1/4 teaspoon salt; 13 tablespoons frozen dairy-free butter (I tested Miyoko's only); 3/4 cup COLD purified water (add 1-2 TBSP as needed)

Question

Accepted Answer

Rolling out the butter in the dough will make this dough sticky in areas. This is why dusting the silicone mat and the top of the dough with gluten-free flour is important. Keep the surface well floured and don't be afraid to chill the dough more often if it gets too soft.
