HOMEMADE JAMMIE BICCIES
As promised, here is @autumnrosewell's recipe for Jammie Dodgers! Her handwritten recipe is covered in tea and smudges of jam, so we've written it out into the thread below #BakingBookshops (Yes, that is an Armadillo, and it is extremely important!)

You will need:
250g Salted Butter
100g Caster Sugar ~ plus extra for sprinkling
1 tsp of vanilla paste, or 2 of essence
230g Plain Flour
A pot of nice jam - you choose! I used Hedgerow Jam because it was all I had in the cupboard.

Baking trays
A wire cooling rack

For this I used two different sized heart cookie cutters - but you can use any shape. You can buy cutters that make your biscuits actually look like Jammie Dodgers, but I prefer things to look homemade. If you don't have cookie cutters, don't worry, I have a cunning plan....

... which is: if you haven't spent your life collecting an entire cupboard full of cookie cutters, you can make lovely Thumb Print Biscuits instead. And small fingers can easily make the thumb prints into heart shapes too, like this:

So my friends, onwards... let's get some biscuits made. Preheat your oven to about Gas Mark 2, 150 degrees (or 130 if it is a fan oven), or use the lower part of the bottom right oven on an AGA.

Cream the butter, vanilla and sugar together until it is really fluffy and goes pale. If you have an electric mixer, use that. (If not, use the mixture to pound out your resentment of the still-latent subjugation of, and data-bias against, women in Capitalist society).

(...we're quite serious, have you read this book?!) Anyway, when your mixture is nice and fluffy and pale, start to add the flour slllloooowwwly. You need a firm mixture, almost a little crumbly, that doesn't stick to your hands or the bowl.

When your dough is ready, roll it out quite thin - about 4mm, but really, guessing is fine. You don't need a ruler. Press out an even number of your shapes and then cut smaller shapes in half of them.

Carefully lift your biscuit shapes onto a baking tray. I chose to keep the little cut out heart shapes, because they see nice to dip in coffee when you need a little boost. But you can just roll the cut-outs back into the mixture if you prefer.

If you are doing the thumbprint cookies, roll a small amount of dough into a ball, put it onto a baking tray and squish it flat with your palm. Then use your finger to press a heart shape into the biscuit. If you have small people around, their fingers will love this bit..!

Once all your biscuits are on a baking tray, put them in the fridge to chill, preferably overnight but for at least an hour if you really can't wait until tomorrow. While you are waiting for your biscuits to chill, practice drawing armadillos. This is is very important! Very.

When you're ready to bake, do one tray at a time. All ovens are different so keep an eye on your biccies. I bake mine for 6 minutes, then turn the tray and bake for another 5. They need to be ever-so slightly tinged with gold at the edges. Careful not to over-cook them because...

we will be putting them back into the oven for a few minutes when the jam goes in, to help it set. So don't turn the oven off just yet.

When each tray is baked, leave it for a few minutes before you lift the biscuits onto a wire rack. Your new biscuits will be very sleepy from the warmth of the oven and it is polite to let them wake up a bit. You do NOT want grumpy biscuits, believe me! Oh gosh no.

When your biscuits have cooled down and firmed up a bit, put a nice blob of jam in the middle of each of the base pieces, and then carefully put the top bit on. Sprinkle the jammed and sandwiched biscuits with Caster sugar.

If you made thumb print cookies then carefully fill your thumb print holes with jam, thus.. and then dust them with Caster sugar.

Put your sugar sprinkled Jammie Biscuits back onto a baking tray and pop them in the oven for four or five minutes. This just helps the jam to set.

Let them cool completely again and voilà! You have biccies AND you've learned how to draw an Armadillo. Now colour in your Armadillo. I did mine in silver, but you could turn yours into a Pink Fairy Armadillo if you like. They really do exist! Google it if you don't believe me.

Pedro the Pink Fairy Armadillo says thank you for reading our thread and enjoy baking your biscuits. He'd love to see pictures of what you bake and has offered to sprinkle everyone's biscuits with fairy dust.

PS: we had a little bit of dough left over so we made these biscuits specially for our friend @OutwoodsCat, who has the most excellent biscuit-paws.
