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.

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?

    Why have I never heard of this before? It looks divine and I so want to give it a go. If it's no bake, that's one less step I can mess up too!
    We did home ec at school, but nothing so exciting as that. I still use the choc-chip cookie recipe and spiced apple tea cake, but most of the others weren't to my taste. A bit old school.

    Hey Claire,

    This is a great recipe, kind of reminds of lemon curd meeting a cheesecake, I imagine it would be the sweetest thing ever. I didn't get to do Home Ec at school either and my mum never had time to teach me how to cook so when I first moved out of home I didn't even know how to boil an egg! It's great how resourceful we can be though, this recipe is testament to that.

    I also love the footnote 'eat until you're sick', I seem to have that problem more often than not these days! :)

      It is a bit like lemon curd/cheesecake combined and yes rather sweet. Wow I wouldn't have guessed that you'd started at not being able to boil an egg!
