You will find that women discuss recipes and menus practically anywhere. Especially around Yom Tov time. Whether at the bus stop early in the morning, or at the beauty parlor: If the recipe is being described with great enthusiasm, I recommend you listen up. You might be onto something great.   This divine sorbet is the result of me tuning in, on one such occasion. It was a week before Rosh Hashanah and I was searching for a fresh dessert idea. I heard Pnina describe this incredibly refreshing sorbet with such passion (pun intended) that it was impossible not to listen. And out came my trusted notebook and pen. I had never heard of passion fruit pulp before. And what a discovery that was! I now stock up on it whenever I’m at Shop Rite.   I have served this sorbet many times since, and will not tire of it. After some digging, I finally found the woman responsible for this creamy goodness: her name is Eva Ben Dayan, and the credit is all hers.
