A few years ago I bought fresh pawpaws from Integration Acres (
http://www.integrationacres.com), based in southern OH. With shipping it was $23 for 2 lbs but I don't know what the pricing is now as the season has ended in southern OH. It looks like they currently have 2lb packages of frozen pulp for $16 + shipping.
If I remember correctly, the order was only filled once the fruit was ready, which was many weeks after I placed my order. A ripe pawpaw is very fragile, so the fruit came very carefully wrapped in newspaper. Fortunately, all my fruit arrived intact although a couple had to be eaten immediately because they were so ripe. The remaining fruit slowly ripened over the course of a few days.
While all the pawpaws had a custardy texture, the flavor varied significantly from fruit to fruit. They were always tropical but some tasted more of banana/pineapple/mango/passionfruit while others also had a richer chocolate/coffee flavor.
I was very happy with the quality of the fruit, but the cost and need to remember to order a month or two early means that I'll probably only buy them every few years.
