The Tart Tang of Spring in an Old Time Prairie Favourite: Rhubarb Custard Squares
Rhubarb is the boldest and bravest of garden perennials and rearing its head in the early frosty Spring, signalling the end to a dreary long Winter. Tingles of excitement sting through me as I dream of the new growing season to come. I cherish plucking young tender greens from my own tiny urban garden for our family table.
And, thus it was. Amid the flurry and flury of the new TM5 Thermomix launch May 6 of this month, I found solace amongst the billowing young leaves in my black wet garden soil where I discovered tender young red stalks hiding, thrusting upward t’ward the sun. Now, is the time.
Of course, there is no time. No time for friends, for family, for me. No time for pleasure, for fun. Only time to work at training our Thermomix consultants how to use their TM5 machines (that was not hard at all) and to certify them to sell the machines with the new changes introduced to our company. Only time for that. I love that work, but where is the balance? Now, is the time.
Freeing each stalk from the mother root, muddy silt stuck to my fingers and worked its way under my nails as tart juices sprayed everywhere. Doesn’t everyone’s nose get itchy at this very minute? Mine did.
Now is the time for Grandma Maude’s Rhubarb Custard Square. Now is the time to treat my husband for doing everything around the house so I can write the training lessons. Now is the time to take this “state of art” TM5 for a spin to see how much more she can improve the quality of my life.
Grandma’s Custard Square is more like a cake. It is definitely not sticky sweet like most squares. Nor is it dense, like most squares. It is, however, flat like most squares. It isn’t tart, like tarts. It isn’t dense or sweet like tarts. It is light and flavourful, yet deeply satisfying very much like a cake. It just doesn’t look like a cake.
But you don’t need to feel too guilty eating a very big piece, like you would if it was similar to a traditional square recipe.
There you have it. Pastry in very few seconds. That is correct. Flour, cold butter, and sugar into the Thermomix bowl and processed for a few seconds.
Done. Then, pressed into the pan. I chose 2 “fancier” pans with bottoms that come out as I decided to serve one to my Thermomix Consultants at our meeting today. I forgot to, though. We were so busy. They left, and the little labour of love was still on the counter. Sigh.
Sugar (brown and white) are beaten with the eggs till light, fluffy and voluminous.
Flour is then gently folded in. The TM5 is much more precise than the TM31. This surprised me. Nowhere did the literature speak about precision, but precise it is.
The digital screen didn’t “turn me on”. Above, left to right: time, temperature, speed.
The scale is more precise: 5 grams up to 6 kilograms!
What did “turn me on” (and I truly wasn’t expecting it) is the guided recipe chip (whooo-hooo! blush!). Of course, I used the machine manually, for this recipe, but the recipe chip builds confidence through its guided recipes, provides outstanding support in the kitchen and creates perfect food every single time. Precision. There are even three automated recipes. Seriously.
I added in the chopped stalks, and ever so gently folded them into the custard mixture. Below, I removed the butterfly (or whisk) as grandma would leave the custard to “set up for an hour, or so”.
But, why not leave it “set” in the pan, before putting it into the oven? That is what I did. Poured the custard onto the base and left it on the counter for about an hour.
Into the oven for 25 minutes at 350ºF and voilà! The brown crispy bits on the top are the best!
The shortbread-like pastry crust is rich and provides the perfect foil for the tart light topping.
And guess what? Vanja likes it! He likes it! You all know that he is the easiest person in the world to live with, but not the easiest one to cook for as he likes really simple food. Most wives would be thrilled about that, but for me, it is a little torturous. I always know when he will not like something, and I always know about recipes I am not sure about (like this one) – so I just hold my breath, cross my fingers, and hope. This minuscule effort of homemade tender loving care was definitely far past due, and finding that he really enjoys it is deeply satisfying! And, as it is simply too easy to make, there is just no excuse! Anytime, can be “the” time.

Please read Susan’s Comment below. She has LONG been someone I have admired. I love her posts, and it was her post that motivated me to fish out grandma’s recipe… I had just found it a couple of weeks ago doing some spring cleaning. But, I copied Susan’s post onto a word document to make it, before typing up grandma’s…. I saved both on my desk top with similar names. When I wrote up the post, I simply pasted the recipe in and proofed it and published it. But, I had copied Susan’s recipe, not the one I had made. I didn’t make her recipe, however.I made grandma’s recipe for the TM5 Thermomix machine, and was busy measuring and converting the ingredients to grams and writing the instructions for that, so I didn’t even look at the other instructions again. I have therefore corrected the recipe, originally identical to the one in Susan’s post. Apologies to Susan, and please, by all means, stop by her site and enjoy it as I have over the years!
Hi Valerie! Wow, what an amazing coincidence that your Grandma Maude’s recipe is exactly the same as the one I adapted and posted just last week right down to the tablespoon! Gotta love rhubarb recipes!
As a matter of fact – let me add your link here, so my readers can also enjoy your gorgeous post. It looks so different than mine!

I would have to say BETTER!

You are so incredibly gracious, Susan. Love your site, and learn so much from you!
🙂
Valerie
Susan, your recipe is pretty much exactly the same as my grandma’s recipe as well, except she added coconut to hers. She also used brown sugar. It was my dad’s favorite as a child. As a recipe developer I’ve learned that there is no such thing as a recipe that’s uniquly yours, because baking is science. It’s all ratios. I could rattle off a cookie base recipe right now, add in a few things, google it and find that someone else has done it. Would I have copied them? No. I could do this in my sleep. All baking recipes are the same science. Also, as someone who has invested months into researching family recipes and old recipes, I can say without a doubt that they are ALL THE SAME. There is no “coincidence”. One person pulls it from a book, the other pulls it from their grandmother’s archives where it was written. Those recipes were passed around and no one knows where they originated from. Our Grandmothers (bless their hearts) would copy down recipes, change a couple things and call them “theirs”. There was no recipe attribution in those days, you clipped the recipes out, added a couple things and then boom! Grandma had a new recipe.
Words of wisdom? Be very, very careful what you claim is “yours” recipe-wise. I’ve seen a cake I came up with “copied” mere weeks after it was popular on Pinterest. However mine was also based on a retro recipe. Was it mine? A little, I did a few alterations. But can I fault someone else for the same retro recipe that has been passed on for decades? No. Not a stitch.
If I went and posted my grandma’s version today, with the coconut, it still would not be mine. Nor would I be copying Susan. Or Valerie. It’s just a recipe that’s been around decades,
Sorry I went on a tangent, but this is a pet peeve of mine. Retro recipes are owned by everyone. As someone who develops them into brand new recipes I can say that changing two ingredients does NOT make them yours.
Now perhaps I went on a tangent for no reason, but the first comment came across as very attacking and like I said, it’s my pet peeve that people think they own recipes when they change two ingredients.
Yup – it was YOUR recipe that made me dig out hers!!!
I think you got yours from a cookbook and added the strawberries.
I should have mentioned you were my inspiration, Susan – but then felt that would take away from my exhaustion… but you most definitely were my inspiration… after seeing your recipe, I had hers from a recent Spring Clean – dug it out – and yup… I didn’t even compare them, to be perfectly honest. If it is identical that is more than serendipitous!

HI Valerie, love your blog. This recipe has been in my family for years. About ten years ago I was in a hurry and decided to do the rhubarb filling in the microwave. Worked amazingly. Poured it on to cooked shortbread base. Spread with meringue and finished off in the oven. Have been doing it this way ever since. Much faster and no dried out bits of rhubarb either. 🙂
Edie
Edie,
Thank you so much! Yes, I think it is that kind of a recipe. That easy. That good. That much in the right place at the right time. Love your tips.
🙂
Valerie
Thanks so much for the clarification, Valerie! Now I know I have another new rhubarb recipe to try which is exciting 🙂
This recipe popped up in my email at the perfect time! I was given some Rhubarb from a farm we visited on the weekend and wanted to use it up. I made this today and it was a big hit! My husband said it’s his favourite treat so far 🙂 Thanks so much for sharing.
Well, that is excellent validation, Tricia! Thank you!
SO happy to hear this!
Sincerely,
Valerie

Hugs
Valerie
BTW I love your new site Valerie!!! I haven’t popped in for a while and look! It’s all gorgeous and new! <3 <3 I
Dear Valerie,
And a Maritime favourite as well! Rhubarb custard is without a doubt a sign that spring has arrived. As sure as apple blossoms and the vibrant purple hue of violets along the treeline. We never grew any ourselves, but were always gifted with armloads of jewel pink rhubarb from our elderly neighbour. It was very generous on his part and my mum ensured that a custard pie was sent back across the laneway in thanks.
This is a wonderful reminder to dig out that recipe!
Thank you so much.
Best,
Mary
Mary,
Your comments always move me.
I appreciate so much, you taking the time to paint an image inside of my head, too!
XOXOXO
Valerie
This is a recipe I have been looking for a few years. My Mim used to make it but no longer has her old and worn recipe books. But Please tell me Approximately how many cups are in a pound of rhubarb?
Answered privately
But 3-4 cups depending upon the size you slice the rhurbarb.
