So, I combined a several different recipes I came across and here's what I made:
2 large peaches, peeled and mashed with a potato masher
1/4 cup orange juice
6 oz. passion fruit Greek yogurt
1/4 cup milk
1 tbsp. honey
1 large peach, peeled and diced
Mix all ingredients together and place in popsicle containers and freeze for at least 4 hours.
This did work out well with the mashing of the peaches. And then I added a diced one in at the end just because I love the chunky texture of fruit. And the passion fruit was a nice addition. I was trying to avoid sugar, so I used honey. It could have used a little bit to sweeten it up. The honey wasn't quite enough and it still was a bit tart, but I wouldn't really want to up the honey and have it overpower the fruit. All in all, not a bad experiment.
