Hi folks, I thought I’d share with you today a surprising discovery – a delightful recipe from almost 100 years ago! The very snappily named “Manual for home storage, pickling, fermentation and salting vegetables, with directions for making potato starch, fruit pastes, butters, etc“, first published in 1917 by the “National Emergency Food Garden Commission” dealt with all kinds of  things related to war-time food preservation and usage of said preserved food.

One such technique it teaches in the book is how to make potato starch, and thus then lists several uses for your cache of potato starch. The recipe which caught the eye of my wife during her read-through of the book was actually the “Potato Starch Sponge Cake” – which incidentally happens to be gluten free and has no added fat. The original recipe calls for a little lemon, though I would recommend increasing this to turn it into a real lemon cake, as opposed to just a “faintly lemon-flavoured” cake. Preparation couldn’t be more simple though care must be taken when combining the beaten egg whites with the rest of the mixture. This cake owes its fluffy, airiness to your success when whisking the whites. If this step fails then I suspect the result may be a rather sorry-looking pancake!

I don’t tend to bake many gluten-free things. Fortunately, I’ve never needed to follow a gluten-free diet, and ultimately I’ve never really seen the point of just cutting gluten out for the sake of it, especially when you need to add in curiously-named things like “psyllium husk” as a gluten replacement. Seriously – doesn’t that sound like something you’d find in a movie about aliens?

Sir, sir – we’re on their mothership and we’ve made our way into the hatchery. The eggs seem to have all hatched, there’s psyllium husk all over the floor… dear God! <crash> <static>…

Anyway, this doesn’t have any funky-sounding stuff inside – we’re talking literally eggs, potato starch, sugar and lemon here. It can’t get more simple than this, and the result is a springy, fluffy, incredibly light cake. You should aim to eat the cake the same day as it will go dry, though storage in an air-tight container should help extend the life by a day or so. Alternatively, if you have dry cake left over, you could do what my wife did and make a delicious trifle with it!

Gluten-free Lemon Cake

The original recipe calls for baking in an angel-cake pan, or a “deep, narrow pan”. I unfortunately had neither, so just used my regular 22cm pan, though you should make sure the pan is quite deep as the cake will rise a lot! My photos aren’t ideal and don’t truly reflect how spongey and delicious this cake is. Photographing slices of cake isn’t my forte, but I hope you’ll decide to give it a go anyway – let me know how it turns out! 🙂

Ingredients

Gluten-free Lemon Cake ingredients

  • 220g Sugar
  • 150g Potato Starch
  • 6 large Eggs
  • Grated zest from 1 Lemon, and 2tbsps Juice

Instructions

  1. Start off by preheating your oven to 150 degrees Celsius. Separate the eggs and then whisk the yolks and sugar in a large bowl until pale yellow in colour.
    Whisking the yolks and sugar
  2. In a separate bowl, whisk the egg whites until stiff and dry in appearance. Fold half the whites carefully into the yolks, and fold in the remaining half when completely combined. Add in the lemon zest and juice and stir gently before sifting in the potato starch, stirring very gently as you sift it in to prevent clumping.
    Whisking the egg whites
  3. Grease an angel-cake tin, if you have one. If not, use a deep, narrow tin, preferably with a removable bottom. Pour the mixture in and then place into the oven.
    Preparing the batter for baking
  4. Bake for 1 hour until the cake is well-risen and golden. The cake’s surface will be crispy, and when you stick a skewer into the cake you will see that it doesn’t quite come out cleanly – this is nothing to worry about. Remove from the oven and allow to cool in the tin for 15 minutes or so.
    Fresh from the oven
  5. Remove from the tin and enjoy. Frost it if you wish, or top with cream and fresh fruit. I found it enjoyable to just eat it with powdered sugar on top.

    Some gluten-free recipes are surprisingly simple with outstanding results.. I’m with you, I’ve no need to eat gluten-free but will try a recipe if it doesn’t have any of that strange sounding stuff added in. This is a pretty cake.. and so quick to bring together, I’ll be pinning this one:)

    I enjoy reading gluten-free dessert posts for curiosity’s sake but won’t likely make it as I don’t have any other use for potato starch and can’t see myself making it from scratch. 🙂 Your lemon sponge cake is remarkably light and fluffy looking. I’d be happy to have a regular sponge cake that looks that good. That said I DID buy tapioca starch a few days ago to make Brazilian cheese bread but it wasn’t a dietary concern.

    Incidentally, I HAVE used potato starch … to separate blood and serum proteins via starch gel electrophoresis when I used to work in a lab at the university.

      Heh, I had no idea potato starch was used for such things! 😮

      I have a huge bag of it… I saw it once in a store… a 1kg bag I think and my first thought was “omg, YES!”… and then I took it home and realised that I don’t actually use it that much. I’ve used half of it so far… not sure what else I can do with it, but this is a good use!

    Charles! Saw this on twitter and on youtube. Looks wonderfully delicious- I really cannot believe it has zero fat zero gluten zero nasties- is that even cake?! Liek you, I have nothing against gluten, though I do like a recipe when it’s got none of the weird sounding gums and shitz added- and of course, looks as yum as this. I am not the best baker but this is one recipe I am going to save and do once I get a bit more time on my hands!

    (p.s. and when I get that bit more time on my hands, I will also sort my paris photos and send you the gorgeous photos of your food and lovely Willie)

Seriously… I don’t want to make a cake with “gum” inside. That sounds way too funky.

    People during the war and the depression had to be so resourceful. I guess recipes like this allowed them to have something for dessert or afternoon tea even if they didn’t have the right rations. I’ve never thought of making a cake with potato starch and this does look like it would be very good in a trifle xx

      Absolutely – that whole book is really interesting. I was reading about other things that happened and the government in England recommended people to eat rhubarb leaves as a way of getting more green leaves in their diet during rationing. Yikes! Sadly, it resulted in illness for a lot of people, and even the deaths of one or two small children :(… so sad!

    I should be eating gluten free but I am not. Can’t bring myself to give up bread! This looks so light and airy, lovely! I love lemon sponges. The problem with most GF products is that they do dry up quick, that’s probably why all those weird things are added. I prefer this cake to any store bought. And trifle’s a great use!

    I have a very similar recipe, although not made for a long time. The gluten intolerant brother in law is no longer on the scene!! Anyway, the recipe calls for potato starch or cornflour. I never had any potato starch to hand and always used cornflour with good results.

      Nice – I wonder if they’re interchangeable… in fact I wonder if any GF flour can be chucked in… chestnut flour for example. It’s not as fine as potato starch or cornflour but it’s worth a try!

    This does look like a beautiful, fluffy cake; and I couldn’t agree with you more about the added lemon. My brother has gone gluten free because it apparently affects your immune system so this cake will be perfect for the Thanksgiving weekend we spend with them. I may even do a sour cherry version so my brother can enjoy the cherry squares (remember my guest post from last year?). The potato starch is a very interesting substitution for flour; and I’m with you, the addition of the weird ingredients is not worth the trouble, not to mention the alien bits!

    Charles, you’re hilarious! Love the mothership scenario…my personal favorite in the gluten-free hemisphere is xanthan gum (followed by guar gum). Though I think most will prefer your account ;-), psyllium husk actually has potent health benefits globally. Far from being inert, it is possibly the most effective natural fiber source on the planet and has been shown to both lower cholesterol and regulate blood sugar (so there may indeed be a point to these things even when you’re not gluten intolerant :)).

    Your cake looks absolutely delightful Charles, and I’ve got some serious love for lemon so this sounds right up my happy alley. (I also think your slices look super – full of light and fluffy).

      Interesting – I had no idea it was so great, I guess there is a reason people eat it after all indeed, although I should start a campaign to have it renamed.

      Yikes, though – something the FDA wrote about it though: “Taking this product without adequate fluid may cause it to swell and block your throat or esophagus and may cause choking. Do not take this product if you have difficulty in swallowing. If you experience chest pain, vomiting, or difficulty in swallowing or breathing after taking this product, seek immediate medical attention”.

      Ehm…. I suppose there’s downsides to almost every food, but I don’t fancy the risk of something ballooning up in my throat and choking me :s.

        Haha! Yes, what people aren’t always aware of is that when you increase your fibre intake you have to also increase your water intake otherwise, ironically, you can end up causing further distress from the swelling action without a liquid source to move it along, as it were. When it comes to a fibre as potent as psyllium (I actually like the name – has a lovely ring, a little bit like ‘Celia’) it becomes even more important. It’s not really scarier than that though (a nutritionist would explain all that to you ;-)).

    Ouffff… I have thought for a moment you went on a gluten-free diet (it’s so fashionable recently and even those who have no intolerance start eliminating gluten). The cake looks fabulously soft and tangy. I must prepare it next time a friend who is on such a diet comes to visit me.
    Actually I have seen some regional potato cakes and even breads in an English cookery book recently! They were not labelled as gluten-free of course but just another kind of cakes.

It’s been a part of baking for hundreds of years, makes no sense to me to suddenly decide to cut it out, and not even for a medical reason!

        I’m still amazed how tall and fluffy this gluten-free cake looks. My mom would have referred to the texture as looking like ‘pamuka’. I always thought the word was Romanian for ‘cotton’ but it turns out the word is of Turkish origin. Amazing how the language develops when you have so many nationalities living in close proximity and having to do business with each other on a daily basis, I guess.

          Is “pamuka” at least the Turkish word for ‘cotton’, or does it mean something completely different again? 😀

    Re: Pamuka = cotton

    Yes, pamuka DOES mean cotton in Turkish. I had to fiddle with the spelling a bit when I checked Google Translate because I thought it was spelled p?muc?. It turns out the Romanian word for cotton is bumbac.

    Of course my Romanian mother made baklava and crepes so I shouldn’t be surprised about the language/culinary cross-overs.
