I am not a big fan of that kind of galettes — rustic looking flat cakes stuffed with whatever. This one is the first I’ve ever made, and the reason it made me curious was a combination of fish and rye. The origins of rustic rye pie with fish, I believe, come from Northen Europe. Kalakukko is a good example. My friend’s recipe inspired me, but the amount of vegetable oil in the dough forced me to go through several rye crust recipes available online just to see what else is out there. There were plenty and all of them overloaded with fat. One, in particular, made me almost give up my search for the low-fat version. It was a very tempting flaky rye crust made with tons of butter using the same method as for the flaky Pâte Brisée. But then I remembered my recently discovered The-Best-Ever dough. I tried using the same method for the rye and wheat mix of flours, and it worked! Again.
