Venn Diagrams.

When just out of college, my friend Martha bought me a cookbook by the renowned Parisian pastry chef Gaston Lenôtre. I was already cooking a lot by then, but I certainly wasn’t up to the level of Lenôtre’s recipes. I certainly spent a lot of time drooling over them, though. 

One in particular caught my eye. It was an orange upside down cake with a pavé of orange slices. It’s like a Venn diagram of citrus! I lost the book decades ago in a move, but the image of that cake stuck with me. (After writing this post, I bought a used copy; when I opened the book it literally opened to the orange cake. This was meant to be.)

I decided to try my hand at my own version of an orange upside down cake. Using my standard upside down method wouldn’t do, as I didn’t want the oranges browned with caramel. But the cake part of the recipe would work just fine. 

I looked to the internet for a cake with a topping like the one I envisioned and found several. I merged and tinkered and tested the top three different ways, and was happy with the final results. To the cake base I add a good dose of cardamom powder and orange zest which gives it a wonderful flavor.

    Just wonderful: the taste and the presentation!
    The amount of cardamom might depend of using the the powder from the whole buds or only of its seeds…

      Thank you, Felix. Here, ground cardamom is only the seeds ground to a fine powder.

      Thanks, Barb — you can see why I was inspired by Lenôtre’s version.

    Hi, David. This sounds so lovely, I am a huge cardamom fan! Can you clarify the amount of sugar used, please?

      Hi Allison — I hadn’t realized I added the sugar twice to the list of ingredients. Thanks for letting me know! You use a total of 2 1/4 cups: 1 1/2 cups for cooking the orange slices and the remaining 3/4 cup for the cake. Hope you are well!

    What a bright and sunny cake, David. There’s something special about an upside down cake — I’m not even sure what it is, but I love making them and eating them! This one is particularly beautiful, and I love the Venn Diagram comparison. And I’m a huge fan of cardamom in baked goods. 🙂 ~Valentina

      Thanks so much, Valentina — I know what you mean about upside down cakes; i feel the same. And cardamom? Such an under-utilized spice!

    Glad you explained the process of arranging the oranges! I would have started arranging them on the outside and worked inward, thereby probably stuffing up the whole thing! My next ‘Venn diagram challenge’ is to do a Lattice Pie Crust- that should be challenging. Your cake looks lovely and I’m sure it’s also lovely to eat!

      I’m sure it would taste just as good in reverse order, Fran! I love making lattice crust. you are going to enjoy it, as well. It’s much easier than it sounds.

    Am smiling – as usual with your posts I look at the artistry of the presentation before I read the recipe . . . just love your photo of the four oranges > shall quietly file that under your name . . . oh, and I love cardamom also . . .

      Thanks, Eha — I do think the cardamom is one of the least appreciated spices. It’s so wonderful, and goes so well with orange.

    Magnificent cake! Upside-down cakes are a favorite of mine, and so far I’ve made 10 versions, each one with a different type of fruit. I’ll hope to find such nice oranges, to make this one soon! 🙂

    I can’t believe how perfectly this cake came out! I’ve made plenty of upside-down cakes (but not orange), and I usually start by trying my hand at a design, but then it inevitably goes awry, and I hope it looks at least a little attractive. Anyway, curious why you didn’t want a caramel? For looks? Or flavor? Or because the recipe that inspired you didn’t use one?

      It took a couple of tries to get it to look this good, Jeff! I should’ve told people why I didn’t do the caramel… First, the flavor would be too strong for the delicacy of the cardamom cake, and second, you would lose the brightness of the citrus fruit with the darkness of the caramel. Excellent questions… Thanks for your nice comment!
