I love it. I was searching for this recipe. Sure glad I found it. I'm originally from Cornwall, which is only a few miles from Lancaster. Boy I sure miss the Perch Rolls. Mmmmmmmmm good!

This sauce had a nice flavor, but it never thickened for me. I did everything per the recipe, and cooked the sauce for 30 minutes before I gave up on it ever getting thicker. Maybe next time I will try adding more flour?

WOW what a surprise. I was a little leary becauce of the mixture of ingredients but what a surprise. Even after substituting eggbeaters and margaring for the eggs and butter it was still great. Might reduce the sugar by a couple of tablespoons next time. I used it on Ahi Tuna and Halibut and got rave reviews. Definitely a keeper.

I am so glad I found this recipe. I'm a university student who lives 8 hours from Cornwall, where I grew up. I was getting home sick and craving a perch roll. You made my week!!!!!

I live in Cornwall and my husband just called to say he had a mess of perch for dinner! Found this and made half the quantity (no water as per another review)and only 1/4 cup sugar. It came out perfect. Having had a Blue Anchor fish roll last week, I feel good about calling it 5 Stars. Could the water be for the bottom of the double boiler??

A very tasty sauce for any fish. Beware, it makes a lot! Delicious!

If you've ever had Lancaster Perch rolls, then this sauce won't disappoint. My husband is a die hard fan of Lancaster perch rolls and he considers himself an expert on the taste of the sauce. He says it's "bang on! No doubt about it!"
