Recipe ReDux:Grapefruit Sherbet & An Ode to Fermentation

grapefruit sherbetRefreshingly Healthful: Grapefruit Sherbet made with Kefir.  

Oh, my goodness…

This Recipe ReDux challenge put me in to full on panic mode when I first saw this months reveal…

September-Fermented Foods-With the start of the school year, get your gut back in gear with natural fermentation!  Think sauerkraut, yogurt, grape juice.

You see, this is the thing…

I was a tad bit tardy checking out the theme for this month’s post, and I had spooky visions of bad college chemistry experiments gone awry as I attempted to ferment something…anything…in a matter of two days, especially considering the fact that the only thing in my life I had ever fermented was to try and turn grape juice in to wine. {Another big time college fail in one of my nutrition classes!}

Thank goodness the fermenting Gods were on my side as I read a little more of the reveal…

Don’t have a yogurt maker or any cabbage to ferment in a bowl?  Tell us how you use your favorite fermented food…beyond yogurt parfaits, if you please!  For inspiration check out this article on fermentation from Saveur magazine. Inspiration for this theme from EA Stewart of The Spicy RD blog. {Oh, wow…That’s me.  I have no excuses for passing on this ReDux!}

Ahh…this was my out though!  I didn’t have to actually ferment something on my own, but instead I could create something delicious with one of my favorite fermented foods…

Sauerkraut?  No thanks!

Kimchi?  Hmm…not a huge fan either…

Yogurt…Been there done that. {Love this Ginger Peach frozen yogurt I created last year!}

But what about something similar, but a little different, and loaded with good for your GI tract buggies…


Kefir on display at Whole FoodsOh my goodness there are a lot of Kefir bottles to choose from!

So here’s what I came up with…

Grapefruit Sherbet made with kefir.

I know what you’re thinking…

It’s fall 1 day before fall officially starts {September 22}, and who wants to be thinking about ice cold sherbet when cinnamon scented apple pies are starting to pop out of ovens??

Well, here’s the thing…

It’s still really hot here, and grapefruit season is still in full swing in San Diego…

…and, really, is it ever a bad time to enjoy a delicious frozen treat, especially when it’s kinda good for you too?

I certainly think not!

Here’s my super easy recipe…

Nutrition Info…

  • Naturally gluten-free and vegetarian.   I used Lifeway Kefir, made from cow’s milk, but you can also find goat’s milk kefir, and coconut milk kefir too, which can be used to make a vegan version of this sherbet.
  • Kefir is a cultured probiotic beverage, similar to yogurt in taste, and made from milk fermented with kefir cultures.
  • Like yogurt, kefir contains good for your gut probiotics, but in greater amounts than yogurt.  In addition, kefir seems to be well tolerated by people with lactose intolerance.
  • Kefir is a good source of calcium, potassium, and protein.
  • Grapefruit juice is a good source of vitamin C and other nutrients. You can read more about the nutrition scoop on grapefruit here.

  1. I tried making a Grapefruit Sherbet sometime last year and I hated it… the recipe called for champagne, and I thought, WOW that will be one awesome dessert… it wasn’t. 🙂 BUT, this recipe sounds amazing…especially with the Kefir! YUMMO!!

  2. OMG!! I love it! I have been buying Kefir religiously over the last 2 months, I love it I just drink it plain this idea is fantastic! I need to get a little more creative with it. I don’t have an ice cream maker so bumm-er! I do love fermented foods. Sauerkraut and Kimchee but who often does a person eat those??!!

  3. did not know (may have suspected) kefir has more probiotics than yogurt. I’m so with you on the lack of desire to ferment myself. I do have some fermented products I like, a great hot sauce in particular.

  4. I love this!! I have never tried kefir.
    In regards to this challenge, there aren’t too any foods I have fermented but want to start.
    I think this recipe would be the way to go.
    I really wanted to participate this month, but had so much going on with starting a new job. I know, excuses, excuses. I will try for next month.

  5. I’m going out to pick up a few grapefruits for the weekend, they look gorgeous in your photo;-)
    I like Kefir but always forget to about it and normally go for yogurt instead. Your sherbet recipe sounds delicious and is just the kind of creativity I enjoy, thanks for your recipe;-)

    1. Thanks so much for stopping by Patty! I’m the same as you re: using more yogurt than Kefir, but I’m going to start stocking it in my fridge from now on. Happy grapefruit eating!!

  6. Great idea – I love the sound of this! I haven’t bought kefir before, only made it at home a few years back. Wish I had thought to make a treat like this with the kefir as I didn’t like it straight up.

    1. Thanks Jeanette! If you like grapefruit, I think you will really like it. My husband and I really enjoyed it last night after dinner. My kids, however, are not grapefruit fans so they each took one bite and wrinkled up their noses. Hmmm…more for me 🙂

  7. NICE WORK!! I love kefir, but I rarely eat it. I wish it was more thick, like yogurt. The flavored ones are always loaded with sugar too, which is a bummer ( and the plain one is just boring, but I love it in smoothies!). Your recipe sounds like a keeper. Not too much sugar at all, but plenty of delicious flavor!

    1. Thanks so much Gina!! So true what you say about most of the flavored kefir’s being high in sugar. This sherbet is definitely lower in sugar than most store bought ones are, and the grapefruit adds such a refreshing twist. Hope you make some!

  8. Wow, this looks SO refreshing, EA. Lol how the Redux challenge was actually inspired by you! It is quickly getting cold here but I can see this as a great alternative to a lassi with an Indian meal. We get some amazing Polish kefir over here, and this looks so easy, no excuse not to try it 😀
