Grapefruit Tarts

I am such a sucker for a good deal. While shopping recently, I noticed that the store was selling 6 grapefruit for $1. Instantly my grapefruit alert levels skyrocketed from Complete Apathy to I Need Six Grapefruit IMMEDIATELY. I tossed them in my cart with Michael Jordan aplomb and gave myself giant pats on the back for being such a clever shopper.

Cut to several weeks later, when six grapefruit are still staring at me accusingly from my overstuffed refrigerator. Suddenly I’m not the World’s Smartest Shopper, I’m the World’s Biggest Sucker, and I need to get rid of those grapefruit stat.

I ate a few of them plain, but I also saved a few to use in a dessert. I haven’t baked with grapefruit since making Grapefruit Meringue Pie earlier this year, and it was definitely time to work some sugar magic on my tart little friends.

I ended up making a grapefruit curd and pouring it into mini tarts, topped with fresh mint whipped cream and a scattering of edible flower petals. (You may be wondering about the economics of buying cheap fruit and then combining them with lots of expensive butter and sugar and cream…shush, shush my pet…none of that logic here…) The important thing is that I got a screaming deal on grapefruit, and put it to excellent use in these tarts. Giant back pats all around.

The best part about these tarts, for me, was the interplay between the tart grapefruit, buttery crust, and refreshing mint whipped cream. I wish I could take credit for thinking up the grapefruit + mint combination, but the truth is, I totally stole this idea from my new favorite book: The Flavor Bible.

I bought The Flavor Bible a few months ago, and it’s quickly becoming my go-to resource when I’m dreaming up new recipes. It’s basically a huge listing of foods, and the flavors that pair best with them. The authors interviewed dozens of chefs and compiled their feedback into lists of complimentary flavors. For instance, in the listing for grapefruit, some of the suggested pairings are Champagne, ginger, honey, lemon and lime, fresh mint, and pomegranate. (There are dozens more suggestions, but you get the idea.) Some of the pairings are obvious, like lemon and lime with grapefruit, or cinnamon with apples, but some of them are combinations I’d never considered before. Ginger-grapefruit scone? I’m coming for you next.

They also include snippets from interviews with the chefs, where they provide mini-recipes for working with these flavor combinations. Of course it’s all subjective, and I’m not sold on every combination listed, but overall The Flavor Bible has been a great resource and a way to spark my imagination. I linked to the physical book, but I bought the Kindle version and just open it up on my computer when I want to consult with it—it’s cheaper, and unlike most cookbooks, I don’t think it loses anything in the formatting or presentation when viewed electronically. (I should note that those are Amazon affiliate links, but I’m not being paid or perked in any way to promote this book—I’m sure the authors have no idea I exist. I just really, really love it and thought you guys might find it useful too!)

My other favorite thing about these tarts was the scattering of edible flower petals on top. It’s amazing how just a few bright petals immediately elevate the tarts from “business as usual” to “hot dog, that’s one beautiful tart!”

I buy my edible flowers at Whole Foods—they’re sold next to the prepackaged herbs in the produce department. I imagine some farmer’s markets might carry them too, but mine does not. It only takes a few petals to make these tarts pop, and so I usually end up adding the rest of the flowers to our salads throughout the week, and we pretend that we are Very Fancy People Indeed.

So there you have it—discount grapefruit, obsessive cookbook reading, and flower munching, all combined into one handy dessert. Just business as usual in the SugarHero kitchen.

Recipe Notes: I always like to add a little gelatin to my curds when I use them for tarts. I think this gives them a little more stability and makes them easier to cut and eat, especially if they’re going to sit at room temperature a bit before serving. The small amount of gelatin in this recipe will make the curd more stable but won’t make it jiggly or gummy. If you’re not a gelatin fan or don’t have any available, it can be omitted, and you will just need to keep the tarts refrigerated until you’re ready to serve them.

Grapefruit Curd Tarts
yield: five 6” tarts

For the Tart Shells:
1 1/2 cups all-purpose flour
1/2 cup powdered sugar
1/4 tsp salt
5 oz cold unsalted butter
1 egg yolk

For the Grapefruit Curd:
1 1/2 tsps unflavored powdered gelatin
3 tbsp cold water
4 oz unsalted butter, at room temperature
1 1/3 cup granulated sugar
3 eggs
3 egg yolks
1 cup fresh grapefruit juice
2 tsp grapefruit zest
1 – 1 1/2 tbsp fresh lemon juice
pinch salt

For the Fresh Mint Whipped Cream:
1 cup heavy cream
1/2 cup lightly packed fresh mint leaves
1/4 cup powdered sugar

To Make the Tart Shells:
Combine the flour, sugar, and salt in the bowl of a food processor, and pulse briefly until everything is well-blended. Add the cold cubed butter and pulse until it is in small pea-sized pieces. Add the egg yolk and pulse in long 5-second bursts until the dough starts clumping together.

Turn the dough out of the food processor and knead it lightly several times to incorporate any extra flour. At this point, the dough can be wrapped and refrigerated for several days. If you’re ready to use it now, spray five 6-inch tart pan with removable bottoms with nonstick cooking spray.

Press the dough into the bottoms and sides of the pans in an even layer. Freeze the shells for 30 minutes, and while they’re in the freezer, preheat the oven to 375 degrees F. Spray the tops of the tart dough with nonstick spray, then press a sheet of foil onto the shells, shiny side down, and fill the foil with dry beans, rice, or pie weights.

Bake the shells for 15 minutes, until the sides start to take on a little color and the center no longer looks raw, then carefully remove the foil and weights. Bake for an additional 10 minutes, until the shells are golden brown. You might want to cover the sides with foil to prevent them from getting too dark. Let the shells cool completely before filling them

To Make the Grapefruit Curd:
Whisk together the gelatin and cold water in a small bowl, and set aside to let the gelatin absorb the water.

Fill the bottom of a double boiler (or a regular saucepan) with about an inch of water and bring it to a simmer on the stovetop. In a large mixing bowl, cream together the butter and the sugar with a handheld or stand mixer until the mixture is light and fluffy. Slowly add the eggs and yolks, and beat for 1 minute more. Add the grapefruit juice and mix—at this point the mixture will look curdled.

Pour the liquid into the top of a double boiler or a bowl that fits snugly over your saucepan. (I actually like to use the metal mixing bowl that goes on my stand mixer so I’m not dirtying too many dishes.) Cook the mixture over the simmering water, whisking frequently, until it thickens enough to coat the back of a spoon. If you want to use a candy thermometer, cook the curd until it reaches 175 degrees F.

Once the curd thickens, remove the pan from the heat and pour it through a fine mesh strainer into a large bowl to remove any bits of cooked egg. Microwave the small bowl of gelatin for 10 seconds, until it is liquid. Add the grapefruit zest, 1 tbsp fresh lemon juice, and liquefied gelatin to the bowl of grapefruit curd, and whisk well. Give it a taste, and add more lemon juice if desired, to get it as tart as you like.

Pour the curd into the baked and cooled tart shells, and transfer them to the refrigerator. Chill until the curd is set. Once set, top with fresh mint whipped cream and edible flower petals, if desired.

To Make the Fresh Mint Whipped Cream:
Combine the heavy cream and fresh mint leaves in a small saucepan over low heat. Heat until the cream is warm, but don’t allow it to come to a boil. Once warm, remove from the heat, cover, and let it sit and infuse the cream with mint flavor for 20 minutes. After 20 minutes, remove the mint and chill the cream in the refrigerator until cold.

Beat the cold cream with the powdered sugar until it holds medium peaks. Dollop the cream on top of the tarts.

  1. I love the Flavor Bible! It’s come in handy so many times when I need inspiration for new flavor combos for the sushi I post on my SushiDay blog.

    These grapefruit tarts are so pretty, and they sound delicious! If I ever have grapefruit that needs getting rid of, this is definitely happening. :D

      Isn’t it amazing? I wish I had bought it years ago–I use it all the time! So glad to find another Flavor Bible fan. I can imagine it would be super useful in dreaming up sushi recipes, too!

  2. Grapefruit curd sounds so amazing! And these tarts look super lovely and cute, I’m loving them so so so much ;-)
    And The Flavor Bible must be a wonderful book, I need to get my hands on it asap!

    • Elizabeth says:

      Thanks Consuelo! The book is AWESOME–I’ve gotten so many ideas from it. It’s perfect when you feel like making, say, a strawberry tart, but want to put a different twist on it. Browse the book, get some flavor ideas, and bam–your own original tart, coming right up. :)

    I think I need to become your new neighbor and I’ll come over and taste-test everything for you. Deal? I think so! You always make my favorite things! :)

      Yeah you do! We give away and toss SO much stuff, it’s ridiculous. Although I suspect you have just as many baked goods in your house as I do–but at least we could do a swap and eat different stuff, right? :)

  4. Amy Murnan says:

    I always think grapefruit is going to be too bitter in bakes and get too scared to try it! These look great though – I have a similar book called the Flavour Thesaurus that I use all the time too.

    • Elizabeth says:

      Don’t be scurred! Grapefruit is one of my faves, hovering in between lemon and oranges on the tartness scale. It’s a nice compromise for people who think lemon desserts are a bit too much. The Flavor Thesaurus sounds similar–isn’t it a genius idea? So glad someone else has done all the work of compiling it so we can reap the benefits!

  6. Becky says:

    I love me some grapefruit cake, but these look amazing. Adding them to my list of things to try! And as far as combining bargain ingredients with expensive ones is concerned, I’m pretty sure they cancel each other out… by my calculations, you made those tarts for free.

    • Elizabeth says:

      Yes, grapefruit cake is awesome! And I LOVE your math. Since these were free to make, and I would otherwise have spent money on dessert, I actually SAVED the family a bunch of money, right? Money that I can re-funnel into more expensive baking ingredients? I’m pretty sure that’s how that works!

  7. Amy Tong says:

    I’m a sucker for good deals too! $1 for 6 grapefruit? I would be getting them home without a second thought too.

    These Grapefruit Tarts are gorgeous and I love the citrus flavor. Wish I get such a good deal of fruit here!

  9. “aplomb”? Really? I’m googling right now. It’s my vocab word for the day. And the sentence, “I always like to add a little gelatin to my curds when I make tarts. . .” I must admit – never made curd, never made a tart. *shame!* There’s just not enough time!! AND I’ve done the exact same thing – bought the great deal and then let it rot in my fridge. Sucker, I am. If I had too many grapefruits? I’d probably have gone the route of marmelade. . . . Your tarts are WAY more fun!

    • Elizabeth says:

      Haha, no shame in that game! There are WAY too many treats in the world, and only so many hours in the day!

      I need to keep marmalade in mind for next time–grapefruit marmalade sounds delicious! Thanks Sara. :)

  10. I have been meaning to get my hands on the flavor bibles for ages now. These grapefruit tarts sound like a refreshing end to summer.

    • Elizabeth says:

      Thanks Nicole! HIGHLY recommend the book. And the Kindle version is pretty reasonably priced! Unfortunately it feels like our summer in LA is just starting, but at least I know what I’ll be eating during the next two “summer” months.

  11. YUM! this looks and sound amazing! perfect for a late summer snack and pretty healthy to boot!

    What a wonderful idea! I think the Flavor Bible might be a book that I need to pick-up soon–I love to try new things, but I’m not always sure of ways to pair atypical flavors. Thanks!
