In order to thicken the sauce, you are going to need to use potato starch in lieu of flour and in lieu of butter, Mother’s parve margarine. The fat and flour are needed to thicken, and matza meal is too course. Potato starch, though, is nice and fine. (Or try cake meal).
rd: thanks, I’m using cake meal so I think it is fine enough to thicken. My father said to forget the margarine though, but I’ not sure why. Maybe I’ll add it anyway.
Thanks for bumping. It was actually quite terrifically good. You may ask any of my siblings (I made it in my parents’ house–I just wrote in-laws to make that joke.)
And we did sing v’osso buco for each line of chad gadya. We just replaced whatever was the new one with buco and then sang whatever was the rest of that stanza.
