Top 100 Five-Ingredient Dinners

I have made this 4 times now, it is delicious. However, it is very crumbly in the middle and is not firm enough for slicing. I add the full amount of flour, but the dough is still sticky. I use fresh milled einkorn and kamut. Should I add more flour? Mix it longer?

I will never use another recipe! I have tried way too many that has resulted in many broken extruder dies. This one was amazing!
