You don't need anything too fancy for this.
: homemade or from the store (I had a 30oz. package and did not use it all for two pies)
(1 box of 19.4oz. was enough for two pies)
I ended up using Dulce de Leche
which was great, but expensive (1lb. and didn't use it all for one pie)
: 2 or you can use the same one twice (Mine is 7 inches in diameter on the bottom)
(Some of my ingredients were for two pies because I experimented first and failed which you will see in the last step.)
