If you're considering taking, or have already signed up for, our online cook school class on Fermentation, you'll find all the details on how to prepare for it on this page.

Below, we have detailed what you'll cook and learn; the equipment and  ingredients you'll need; and any advanced prep necessary. Note: A measuring scale and three glass pickling jars required for this class—two 350ml jars and one 750ml jar. Used jam, pickle or condiment jars are suitable as long as they are around the same size. Please sterilise them before class. (It’s simple! Instructions below.)

Once you've signed up for the class, we will email you all the details on how to log onto the Zoom call, PDFs of the recipes, and a reminder of the following information. This class is restricted to students aged 16 and older.

What You'll Cook (& Learn)

- Korean kimchi
- Moroccan preserved lemons
- Cucumber pickles

By making these pickles, you'll learn about safe home caning practices, pickling techniques from around the world, how to get creative with pickles and their flavourings, and how to use pickles to add punch to any dish. These three pickles are just a starting point. 

This class can be adapted for vegetarians and vegans (by omitting fish sauce in the kimchi). It is naturally gluten-free. 

The ingredients yield three jars of pickles. If more than one person is taking the class, you have the option to divide the work or make the recipes individually and have plenty of leftovers.

2 large mixing bowls, for mixing the pickles
Chef’s knife, for cutting ingredients

- 1 750 ml jar (we love this Lekue Pickling Kit, which includes two), for canning
