Hartree tart

My mum is from the bush so like most bushies, went to boarding school. She tells us lots of great stories from her school days like why she now has a tablespoon of Vegemite on a centimeter of toast, but the best thing she has shared with me recently is her recipe for Hartree Tart. I so wish there was such a thing as Home Ec when I was at school. I think it would have been much better for me than learning about metalanguage (don't ask!) in English.

If I'd been able to take Home Ec I might have learned something like mum's recipe. As soon as I tasted my first bite of this I send mum a text:

'You are a neglectful mother! How can you have never made us Hartree Tart before?!? Now it's your fault if my dress has to be let out!' I can't believe she has kept it to herself for all these years but I was very happy to receive the recipe at my bridal shower.

Hartree tart

My grandma wrote the recipe out originally with the footnote 'eat until you feel sick.' I can see how that would happen because it's very hard to stop at one slice. My grandma also said that mum was so proud of her recipe she used to make it for every occasion. She thinks mum must have made it literally 100 times. Because they weren't allowed to use the oven at school, the recipe is a no-bake so it's a great one for the kiddies. Because it's no-bake you need to make sure you use very fresh eggs.

Last month I skipped entering the Sweet Adventures Blog Hop because my brain was way too full of wedding stuff to be creative but when I saw that this month's theme was lemons I knew I had to make this. So this is my entry in the April Sweet Adventures Blog Hop-Lemons.

If you want to be a part of it, head over to Delicicieux to read the instructions. Happy hopping!

The ingredients

You can see why it was a good recipe to teach kids. There aren't too many ingredients. It also makes it very budget friendly.

Bashing up the biscuits

The first step is to crush up the biscuits. Now of course you can do this in a food processor but seeing as it's a 40 year old recipe, I thought I'd do it the old-fashioned way and use some elbow grease. It didn't take too long to bash them all up.

Adding the butter

Then pour in the butter and mix it all together.

Into the tin

Press the biscuit mixture into a greased fluted, loose bottom tin. If you don't have a loose-bottom tin it's no drama. You can just serve the finished tart in the tin or dish. It would look rather pretty like that too.

Condensed milk and egg yolks

Now it's time to make the filling. Stir the condensed milk and egg yolks together until it's nice and smooth.

Adding the lemon juice

Then add the lemon juice. I switched to a whisk at this stage and mixed it all up well.

Filling the shell

Pour the mixture into the shell and then put it in the fridge to chill.

Beaten egg whites ready to be sweetened up

While the filling is chilling, beat the egg whites until they're stiff. Add the sugar a little at a time and keep beating until it is smooth and glossy.

Meringue topping

Spread the meringue over the top of the tart and fancy it up a bit with the back of a spoon.

Sun-kissed

You could finish it off at that stage but I wanted an excuse to use my new brulee torch. Let's just say I need to work on my skills a bit. I was going for the sun-kissed look but I think I ended up with something a little more like the I-missed-some-spots-with-the-sunscreen-and-got-patchy-burns look. Put it back in the fridge until it's nice and cold.

Out of the shell

Very, very carefully remove the tart from the shell.

Hartree tart

I decided it needed a little bit of something extra before I served it so I topped it off with a few little pieces of lemon zest. Perfect!

Hartree tart

Slice it up and serve it with whipped cream and/or ice-cream and as per my Grandma's instruction, eat until you feel sick. Enjoy!

So what about you? Were you lucky enough to do Home Ec at school?

  • Spread the egg mixture over the crumb base and refrigerate until chilled.
  • Meanwhile, beat the egg whites until they are stiff and then gradually add the sugar. Continue beating until it makes a shiny meringue.
  • Spread the egg white over the lemon layer.

      Oh no I couldn't live without my oven either. The element died on me a while ago and I nearly cried! Luckily it was fixed quickly.

    How wonderful to have a recipe passed down through the generations. I did take Home Ec and fondly remember making funnel cakes in 5th grade - fried dough doused with sugar - thank you America-land! The tart look delicious!

    Oh boy that looks good, Claire. I think I could keep eating this until it was forcibly taken away from me :)

      Yes it's one of those recipes isn't it! Not too sickly sweet to make you want to stop.

    I wish I'd taken Home Ec to. What a great recipe. It looks old school but something that all of us should have in our repertoire. Love lemon and meringue - amazing and unbeaten combination xx

    The tart looks delicious! But believe me no home economics is not a bad thing, I was forced to do it for 3 years and hated every minute and it put me off cooking for years!

      Really Nic? Maybe I have a rose-coloured idea of what Home Ec must have been.

    LOVE old recipes like this - there's always a good story behind them.
    I think 'eat until you feel sick' should be the official postscipt to all your recipes!

    What a fantastic recipe Claire. I love the footnote of "eat until you feel sick"! That made me laugh, as did your text to your Mum. Like Lorraine, I was wondering where the name came from. You'll have to let us know.

    Oh I can see how this could be addictive. The lemons cut the sweetness until just after you have eaten your third piece and thats when the sickness would hit. Very nice to have a recipe thats passed down.... you need to give it a family name!

      That's about when it hits, yes! It seems that mum might have made up the name because she has no idea where it came from!

    Dont know where the name originated! It wasn't after any teachers...cant really say. It used to be very yummy 'tho!

      I didn't realise it wasn't something well known until I just Googled it. I'll ask mum and get back to you about the name. I have a feeling it's named after a teacher.
