I'm not sure why they took off my recommendation when I posted the recipe - I suggested serving them with a roasted red pepper sauce, but tzatziki or something similar would be just as good. Definitely better with some sort of sauce though, I agree!
Just a comment for everybody on the stiffness - it is a pretty stiff batter, but one thing that might help is that I weigh my flour - 303 grams is about 2 1/4 cups for me, but your flour may be heavier/more packed! Try weighing out 303 grams and see if that helps. :) Thanks!
