I've made these a few times and whenever I've pan fried them, they're just wrong. The flavour is awesome but they are still soft and a bit stringy / undercooked inside and undercooked seitan just makes me gag!!
So I baked them and they were absolutely stunning! With some plain sugarsnaps and sweet potato fries. Mmm Mmm MMMM!
I also borrowed the mustard sauce recipe from V'con to go with. I say borrowed as I didn't have exactly the right ingredients. I subbed dijon mustard for the wholegrain called for in the recipe and I subbed arrowroot for the cornstarch. It was really REALLY good (I'm loving mustard lately!) and luckily there's some left to go in a sammie for lunch tomorrow with the leftover cutlets. YAY.
