We have all heard stories of people hoarding things during the COVID-19 crisis. One such thing is yeast. When biologist and yeast expert Sudeep Agarwala discovered this trend he took to Twitter to share his recipe for making yeast so no one would have to do without.


"Friends, I learned last night over Zoom drinks that ya'll're baking so much that there's a shortage of yeast?! I, your local frumpy yeast geneticist have come here to tell you this: THERE IS NEVER A SHORTAGE OF YEAST. Here's where I'm a Viking. Instructions below," wrote Agarwala on Twitter.

An easy recipe

The recipe is easy to follow. After all, it can be communicated in just a few Twitter posts. This makes it all the more appealing.

Begin by getting dried fruit. Fresh fruits work as well but since it is recommended that they be left unwashed this may not be the best time to use them.

Put these fruits in a jar with water and twirl them. "If you stir the fruit around, you'll notice the water gets slightly cloudy. That's the yeast!" wrote Agarwala.

Then add some flour. The flour should be equal in mass to the fruit and water or enough to make a loose wet dough. Agarwala explains that the dough need not be fancy. White flour is fine.

After that, you need to wait and keep it warm. "You'll want to keep this warm (but not hot). Hug it while you binge Netflix. Cuddle it while you yearn for human touch once again. Or put it on the counter while your dishwasher is running," wrote jokingly Agarwala.

If you have done this process correctly, after 12 hours you will see bubbles. "Once the flour paste loosens up (24? 48 hours?), take a tiny bit of the fruit/flour/water mix, and add it to 30-40mL of water, add flour, and repeat. This time, it should come to life and those bubbles should pop up much quicker," wrote Agarwala.

That's it, folks! You now have your very own homemade yeast. Agarwala even suggests you get creative using other ingredients like some old bread you have lying around or some wine. The key is to have fun!

It seems like a great way to stay entertained during social isolation. Will you be making your own yeast soon?
