Boiled sweet potato(still hot or warm when combining with the flour) heat up the sweet potato if you are using left over. All purpose flour 1:1. I used Jovial organic einkorn ancient flour. Sea salt, a pinch or two.
I did not want to use my hand but I had to.
I tried to use griddle cast iron. Melted coconut oil.
It was better in smooth surface. Make sure you invert after just placing the dough in the pan to spread coconut oil better.
So to absorb the oil...
Rub more coconut oil so it won't be hard.
