Mandarin Orange Yeast

Mandarin Orange Yeast

This yeast is made using honey and seasonally available mandarin oranges. I'm posting it here in a day-by-day format. This orange-colored liquid yeast has a beautiful aroma.


Mandarin oranges
1-2 (enough to fill 1/3 to 1/2 the jar)
about 1-2 tablespoons
about 2 to 3 times the amount of mandarin orange


1. Prepare a sterilized glass jar with an airtight lid. Peel the oranges, and separate into single sections. Put all of the ingredients (2 oranges, 2 tablespoons honey, and water) into the jar. The next step is to shake the jar once a day, or stir it with a stir stick, open the lid and smell it.
2. Day 1: This is what it should look like after all the ingredients are combined.
3. Day 3: The mixture should be cloudy and start to form tiny bubbles.
4. Day 6: It should be bubbly. Just one more day!
5. Day 7: The oranges should be floating, and the mixture should be fizzy.
6. Fizz!
7. Strain out the oranges through a tea strainer. If you don't plan to use the liquid yeast right away, you can store the mixture in the refrigerator without straining out the oranges.
8. Store in jar. I store it in the crisper drawer of my refrigerator. It should be used up within a month.
9. If you leave 1 spoonful of the liquid yeast and add it to a new jar of mixture, it should fizz up within 24 hours. Just add 1 mandarin orange, 2 tablespoons honey, water and 1 tablespoon of the liquid yeast.

Story Behind this Recipe

I wanted to make natural yeast from fruit in season, and so I decided to use the mandarin oranges I had on hand. I love the aroma of citrus, so it was fun to make mandarin orange yeast liquid.
