While I may take some heat for saying it, I fully subscribe to your grocery store classifications 🤣🤣.

I am constantly looking for passion fruit puree wherever I go. The most accessible really is Amazon. It's a large portion, but as others have stated, you can freeze 1 oz cubes and use as needed later.

Cheers and good luck my friend!
