Content note: this post is about food
A few weeks ago Britain had its first taste of food shortages after it voted to crash its economy. Unilever briefly stopped supplying Tesco due to a dispute about prices. Around the same time, disgraced former former minister Liam Fox, who is currently in charge of figuring out post-Brexit trade, issued a call for innovative jams to become one of Britain’s chief exports.
In this climate, I decided there was no time like the present to start making a yeast extract from my vaginal sourdough starter: again, it’s my damn scientific mind, which sparked previous weird experiments. It took me a while, but the results were quite promising, and if Liam Fox won’t eat it, it just shows he has no confidence whatsoever in Brexit. Or British Values, because I’m sure making my own cunt marmite when there was a shortage is the epitome of that make-do-and-mend Blitz Spirit.
So, the headline: yes, it’s possible to make a quite tasty yeast extract spread from vaginal yeast, but my god, it’s a massive *puts on sunglasses* faff.
Now, the full recipe is currently available to patrons only, although will be made public in a little over a month. For as little as $1, you can read the recipe now, completely free from the trappings of recipe stories on blogs. When I make it public, there’ll be a lot of scrolling.
Let’s begin at the end, when I finally ate the damn stuff. What did it taste like?
Answer: not like marmite, but tasty anyway. It was sort of sweet, like chutney, with a strong umami edge: not as strongly umami as marmite, but more like the more delicate flavour of vegemite. The closest thing I could compare it to is brown sauce. I had very low expectations for the project, with my bar set at “Troll Everyone” with bonus outcomes being “Actually Produce Something Edible” and the most unreachable desirable outcome being “Edible And Actually Quite Nice”. Somehow, I succeeded in the Edible And Actually Quite Nice, with nobody being more surprised than me.
And why was I surprised? Because it started life as this:
That right there is some of my sourdough starter (to which, you’ll remember, I added some vaginal juices when I first started growing it), modified to make it more liquid and therefore frothier. Literally nobody, as far as I could discover, has ever made yeast extract from sourdough starter, so I was having to improvise the whole thing from start to finish. Recipes tended to call for either bakers’ yeast or brewers’ yeast. Having neither, I settled for making something which had a consistency somewhere between the two of them. It took a couple of days to get the yeast ready.
Yeast extract is made by autolysing yeast. In lay terms, this means forcing the yeast to eat itself and then enjoying the delicious, tasty by-product of its own self-destruction. It’s probably a pretty decent metaphor for the Tories, which is another reason why Liam Fox should definitely eat my vagemite, unless he’s too chicken.
In practical terms, autolysis is triggered by incubating the yeast at a precise temperature, or under a precise pressure, or a little bit of both. It’s also helped along by salt.
If you’re making yeast extract in a factory, you’ll need specialist equipment to put it under pressure, keep it at a very precise temperature, getting the pressure right, and so on and so forth. Hell, if you’re making it at home, you probably need some specialist equipment: some recipes call for a pressure cooker, while others call for a hob where you have a decent amount of control over the temperature. I have neither of these things, but I jury-rigged a very high-tech incubation chamber anyway.
The full recipe explains exactly how I autolysed yeast without any specialist equipment, and it actually did work, to my utmost shock. The picture above shows the yeast after the incubation. The dark band is the yeast extract itself. That’s what yeast extract is: a dark liquid that comes off of autolysis of yeast.
I incubated it in total for about 26 hours: I’d intended to do 24 hours, but I was playing a really awesome game called Night Witches with pals, so I was out for a bit longer. Strongly recommend playing Night Witches, by the way, if you like any of the following things: communism, planes, women’s history, yelling DAKA DAKA MOTHERFUCKER at imaginary Nazis.
A few hours into the incubation, it started smelling a bit like marmite. 15 hours in, and it definitely smelled like marmite. Once the incubation was done and I strained it, I sneaked a taste of the yeast extract, and it tasted… not like marmite, nor vegemite, but maybe the cheap off-brand yeast extracts you might end up accidentally buying.
I left it to separate further for a couple of days, and then my next task was to reduce it down from a liquid to something with a consistency of marmite, and to flavour it. While you can eat yeast extract on its own, and you can buy that from health food shops, it’s pretty horrible, so you need to flavour it. Even proper marmite is flavoured a bit.
I used the water from boiling vegetables to flavour mine. Specifically, I boiled up two carrots, a small pumpkin, some baby pickled onions and a normal onion. This probably explains why it has that sweet edge to it, because carrots and pumpkin are both quite sweet, and maybe my tastebuds are weird, but I also think baby pickled onions are sweet. Incidentally, I only used pumpkin because the recipe I’d seen called for turnips, and they didn’t have any in the shop, but they had loads of pumpkins. Here’s what it looked like when I multitasked reducing the yeast extract and boiling veg:
I then plonked the vegetable water into the pan with the yeast extract, and let that reduce. While it was still liquid, it would have made a passable gravy.
Sadly, I had to keep on reducing. And I reduced and reduced, until eventually, after a week, I managed to produce… probably about 3 tablespoons of vagemite.
I let it cool, and then I ate it. I ate the whole fucking lot of it, because it was surprisingly nice. It seems like sourdough starter doesn’t produce quite as much yeast extract as more conventional yeasts, so if I were to do it again, for, say, when Liam Fox eats it to prove he has confidence in Brexit, I’d probably use a lot more sourdough starter than I did here.
I think it would probably go quite nicely with a sharp, mature cheddar in a sandwich, or perhaps in a savoury cheesecake made with quark.
So what have I proved here? That, in the event of a second marmite shortage as prices rise after Brexit, you can make it at home reasonably cheaply, but it won’t particularly taste the same. That it’s probably much better mass-producing the stuff. That it is a lot of fucking effort to make marmite, but it is possible. That you can make it out of sourdough starter and it doesn’t–as all the forums said while dismissing the idea–taste in the least bit funky. That Liam Fox is a fucking wanker… but I didn’t need to take a week of fiddling about with yeast to know that.
