Inca's Food Aji Amarillo Yellow Hot Pepper Paste - 7.5 oz

Which one is better, this or Dona Isabel?

I just ordered this and when it arrived it’s sealed but out of date and a more orange color than yellow. Is that normal?

In Bolivia, we have a dish called, Fricase and we usually use aji amarillo en polvo, does anyone know if i can use this aji amarillo to make fricase?

How much of this paste would I use to sub for an aji amarillo pepper?
