Chicken Wings, Katsu Sauce Recipe Book: Nigel Slater - Eat Review: ⭐️⭐️⭐️⭐️. Very nice. For us it didn’t quite hit the spot for a 5⭐️ but it was still good. We had loads of sauce left so next time I’d make half the portion of sauce. It tasted a bit like satay your me even though there was no peanut butter in it. I had to substitute medium curry powder for mild as I didn’t have any mild in, but it tasted good regardless. Easy enough to make, basically chuck all the sauce ingredients in the blender. Aga conversion: I did most of it on the hot plates, I used the boiling plate for the first 5 minutes and then simmered for 30 minutes on the floor of the simmering oven. I did the final crisping you fry on the boiling plate. Will I make this again? Yes it was good, probably just use chicken breast next time as it was a bit messy to eat though.
