Top Tip: How to use small intestines in the classroom
Porcine small intestine
I heard this from a lab tech from northern NSW at ConQEST. She did such a good job with the small intestine in the science classes that now she’s asked to bring it into the hospitality classes as well.
She puts the specimen into an ice cream container and lets a little bit hang over the side. Then she gets the kids to gather around and guess at what it is. They can touch it at this stage but they can’t see what it looks like in the container.
After a while they get to see it all coiled up in the container and everyone gets around to working out that it’s a small intestine. Then they start to wonder how long it is. They’ve heard that these things can be metres long, so they are allowed to start extending it out.
They pull and they pull and they pull. Eventually they are all standing holding this thing and then the labbie gets the tape measure out. It’s around 6m long.
All the while these kids have been hearing about what the purpose of the small intestine is, where it fits in the jigsaw puzzle that is your abdominal cavity and what it connects to and so on. They are fascinated by the thing and asking lots of really good questions. Before they know it these kids can spout off all sorts of fun facts about their digestive system. Teaching by stealth – I love it!
The specimen is tough enough to handle this over and over again. You will store it quite happily in the fridge for years before you need a new one. If you’re willing to you can sacrifice a little bit and make a wet mount to be viewed under the microscope. Look out for the little ‘hairs’ along the edges – those are the remnants of all the circulatory system structures that bring oxygen to the small intestine and carry fluid away from it.
This is definitely a specimen that gives you a lot of bang for your buck.

Digestion Suggestion: Peanut Butter Pudding

When one of us has a birthday we like to take the opportunity to have a proper weekend away. It only happens twice a year and we don’t get much time off together so we like to celebrate in style. This year for Mr Vivi’s birthday we took a 3 day weekend in Brisbane, saw the Mummy exhibition at the Qld Museum and had dinner at Smoke which we’ve been trying to get to for over a year. Great food, great wine and great company was surpassed only by the dessert special – Peanut Butter Pudding.
It was heaven in a little cup and the whole table almost cried when Mr Vivi knocked the glass over and we thought all was lost. Never fear because I have toiled away in the kitchen since then to recreate the experience at home so you, too, can taste a little bit of the amazing meal we had at Smoke. With the right ingredients this recipe could be made entirely gluten free.
I started with this recipe and have tweaked and twiddled until I got it just the way I wanted it. In truth, it’s just a really basic pudding recipe that I can flavour any way I like now, and I’m quite keen to have a go at it using Nutella or perhaps some of our Backhousia citriodora which is lovely in melting moments.
This recipe must be foolproof because Mr Vivi managed to make his first batch as I yelled instructions to him while I was trying to put my makeup on 20mins before we screamed out the door to a BBQ. The secret is in using a whisk to get a smooth, creamy consistency.
So, without further ado, here is our recipe for peanut butter pudding. I thought you deserved a sweet treat after your first week of Term 4. Let me know what you think, won’t you?
Peanut Butter Pudding
1 3/4 cup milk
1/2 cup cream
1/2 cup sugar
1/2 cup peanut butter
slurp of vanilla
2 1/2 teaspoons cornflour
Peanut butter pudding ingredients
Keep about 1/4 cup of the milk aside to dissolve the cornflour later.
Combine the milk, cream, sugar, peanut butter and vanilla in a saucepan.
Peanut butter pudding ingredients on the stove
Whisk over low heat until the sugar is dissolved and the peanut butter has melted and blended through the mixture.
The mixture can be steaming hot, but don’t let it boil yet.
Peanut butter pudding cornflour and milk
Blend the cornflour into the milk that was kept aside.
Add the cornflour slurry to the mixture on the stove and stir with a whisk.
Bring the mixture to the boil while whisking and let boil for about a minute.
