I’ve been making this for years and it’s always good and enjoyed! I sub oil for the margarine and it’s fine. I also make a Pesachdik version and have used it as a base for appetizers, like some sort of chicken or meat mixture on top.
does anyone know if can sub oil for margaring in this recipe
You should be able to but I haven’t tried it so not sure if the measurements would be exactly the same. My concern would be if it became too oily.
i would like to make this for yom tov, however i want to know if i can sub the margarine for oil
Hi Tamar,
I actually just tried this recipe and yes, you can substitute the margarine for oil (for every 1 tablespoon of margarine do 3/4 of oil). I used avocado oil (4.5 ounces) and had good results!
