"This was disappointing. It was beyond bland even after adding more salt and even adding garlic. I'm sure I'll end up throwing this away."

"Followed the recipe precisely, easy to make. It tasted ok, just a bit bland. I will definitely make this again, but will add more S&P and ground mustard, and will probably add some garlic for sure!"

"I made only a half a batch because there are only 2 in household. I didn't any other changes and it was very good."

"Excellent taste and everyone loved it. I made it in the microwave in a covered stone cooker due to conflicts with the oven and it turned out great."
