Yesterday, a friend of mine stopped by with a gift from her back yard. She has a graviola (soursop in English) tree growing there, and we're currently in the middle of the harvest season for graviola here in Fortaleza. She's overwhelmed with graviola, and kindly brought a good-sized one over as a present.
The fruit was very ripe, and I knew I had to do something fairly quickly with it, even though I refrigerated it immediately. I am a total fan of graviola juice, and so decided I would make fresh juice with the aid of my blender. I snooped around the internet a bit before I started, and found a suggestion to add the juice of one maracujá (passion fruit) per jar of graviola juice, which I thought was a wonderful idea. First, because I love maracujá. Second, the highly-acidic juice of the maracujá might cut the sometimes-sticky, custardy flavors of the graviola and would provide just a bit of a bite, which seemed to me would be a good thing. Fortunately, I had a couple of maracujás in the house, so I didn't need to go shopping before beginning.
I started off with one medium-sized graviola, very ripe.
First, I cut the graviola in half, and with my hands pulled the pulp out from the halves, seeds included.
I placed the pulp in a blender, and blended until the pulp was pureed and smooth. I then strained the pulp through a small sieve to remove the seeds and seed bits, plus any woody remainders of the pulp.
Then I poured the strained graviola puree into a juice car.
Next up was the maracujá.
I cut it in half, blended it and strained it just as I had done with the graviola. I was left with a small amount of juice that was very concentrated and acidic.
The juice was creamy and rich, and absolutely delicious. Pure graviola juice can be overly aromatic and almost cloying in texture and taste, and I thought the maracujá juice was exactly what was needed to avoid both of those problems. The juice still tasted like graviola juice, not maracujá juice. But it was tamed by the presence of maracujá and certainly made more refreshing. From here on out, I'll not make graviola juice without adding that magic ingredient - maracujá.
