Maths & Baking Part 3

Well, after the fun that was the Science Grrl launch and the whirlwind of Eat Your Heart Out Mr Quirky and I were really looking forward to a fun night out as Festival of the Spoken Nerd made their long awaited visit to Derby. Well, how could I resist the excuse to spend my day off doing more baking!

First up were the props for the show. Back in the summer Matt Parker asked if it would be possible to make some custard creams in the shape of a Pythagoras triangle as a surprise for the last show in FOTSN’s run at the Edinburgh Festival Fringe.  How could I resist!  I’d thought a little about how to decorate them but my first attempts were less than satisfactory, so I was glad of the chance to have another go.   This time, I took inspiration from making Hot Cross Buns, and simply thinned down some of the biscuit mixture with milk in order to produce a piping consistency.

I settled on a suitably maths related decoration – you might just be able to spot the infinity and pi signs I piped around the edge to mimic the classic custard cream design.

Following on from my musings on a Menger Sponge cake I decided to go back a step and make a cake based on the basic Sierpinski Carpet pattern upon which the Menger Sponge is based.  A Battenberg cake seemed the obvious way to go.  You could make it in any combination of colours and/or flavours.  This one was chocolate and vanilla.

First you make all the sections – easy in a Battenberg tin.

Then you simply trim and assemble the cake, as you would for a normal Battenberg.

Of course once you’ve made one section you can make your Sierpinski Carpet Cake as big as you want.  I did contemplate making one of the subsequent iterations, but the combination of only having one tin, and baking with a migraine meant I settled for this one.

We had a fabulous time at Festival of the Spoken Nerd – if you’re as geeky as us and like your comedy too then do go and see the show if you can.  One last thing – I haven’t yet given up on biscuits of constant width – as soon as I can get hold of the supplies I need I’ll be baking as long as it takes to nail that one.

Ada Lovelace Day

I’m continually inspired by science in producing the cookie designs for Quirky Cookies & Cakes.  So in honour of today being Ada Lovelace Day here’s a sneak preview of two of the cookie designs I’m making for the launch of the Science Grrl calendar at the Science Museum this Thursday.  Can you guess what the cookies are?

Do have a read about Ada and what she accomplished in her lifetime,  She really was an inspirational woman.  You can find out more about her on her Wikipedia page or there’s a Radio 4 programme about her here.  Why not join in with the celebrations and share a story about a woman scientist who has inspired you.

Maths & Baking – Part One

I’ve been thinking about this blog for a while.  It all started when I did the Geek Calendar cookies last October.  Here’s some of my maths cookies from that night, ably modelled by Matt Parker & Alex Bellos.

By the way, please, please do go and read Alex’s book “Alex’s Adventures In Numberland“. Now.  It’s utterly absorbing.

Now, I want to start by admitting that maths was about as far from my favourite subject as was possible when I was at school.  In fact I always thought that I was pretty rubbish at maths.  Six hours of possible brain injury testing after the accident proved otherwise, but that’s a whole other story.  The point is, I THOUGHT I couldn’t do maths.

It’s only with the passing of time, (well that and listening to Matt Parker talk about the beauty of a Möbius Loop), that I’ve realised that I really like maths.  I’m relatively good at it too: cue competitive “discussion” with Mr Quirky as to who’s best at navigating & packing the freezer (although I have to admit, that time he navigated through London using only the sun was awesome!).

The reality is I use maths all of the time in my work. From simple multiplying and dividing ingredient quantities, through working out percentage profits to the more complicated geometry for some of the sculpted cakes.  Whilst leafing through Hannah’s GCSE Higher Maths book, I even came across an example of using maths to ensure the right number of trays of eggs is ordered, a “Real-Life problem” I calculate every Monday! Although Ed-Excel, I have to point out that a tray of eggs is 30 not 24!

So in honour of this being Pi Approximation Day, here’s  some fun maths cookies and cakes.

Quirky Junior’s fantastic maths teacher Mrs Boyd is leaving us for the USA, and to mark this sad day  Hannah made some fabulous maths based cookies this week.

They reminded me of some I helped her make 3 years ago, before I set up Quirky Cookies & Cakes.

You can see how her piping has improved from age 11 to now.

I’d been thinking about a Möbius loop cookie for quite some time, so Mrs Boyd’s departure seemed the obvious time to have a go.  My normal cookie recipe didn’t stand up to the cooking process so I decided to try a fortune cookie mix.  I’d never made them before but I just about managed to get it to work. Next time I’ll know to make the strips of fortune cookie at least 30cm long, as most of the ones I made simply weren’t long enough to fold back on themselves.

I’ve had some helpful suggestions as to possible improvements from BakeMe.Com and my good friend Jules of  Butcher, Baker I’ll be returning to that one as soon as I’ve got the energy!

I couldn’t let today go by without making at least one pi cake.  Having compared methods with @standupmaths following his pi cupcakes earlier this year I thought it should be possible to use the marbling method to make a cake which, when cut, showed the pi symbol.

Well, it clearly needs more work, and if I hadn’t been spending most of the day finishing these and a plethora of other things, I’d have made another one.

One final thought…we were honoured to welcome Matt Parker to Quirky Towers earlier this week when he was working in Derby.  Whilst we happily chatted about maths and baking, I suddenly had the idea of a Venn Diagram pie.  I’m working on it now…so watch this space for more maths baking fun soon.
