Tepache, Tibicos, and Simple Mead

with Soirée-Leone

Explore the tasty world of fermented beverages including tibicos, tepache, and a simple mead. Tibicios is a traditional Mexican beverage that is known by many names, including water kefir, and is fermented using a SCOBY (symbiotic community of bacteria and yeast) that forms into grains. It can be flavored in a zillion ways including using food scraps! Tepache is another traditional Mexican beverage made with corn and often these days is made with pineapple scraps. Mead can be a bit daunting so here we will start with a simple mead using just honey and water to get folks started on a mead making journey.

Soirée-Leone has chosen to support Middle TN Black & Indigenous Support Fund, a community fund for Black and Indigenous queer and trans folks living and participating in the gayborhood and queer community of rural Middle TN.

Citrus Surplus Situation

with Jess Wang

** Due to technical difficulties, the official recording of the workshop was lost. However we are able to offer a shorter recording of Jess on the same subject from last year’s Ferment for Food Justice event. The recording does not touch on the fermented citrus cleaner, but you will receive Jess’ written instructions on how to make the product when purchasing this recording **

Learn how to make the most of your citrus through fermentation: preserve high acid citrus for adding depth to your cooking, and prep your own all purpose surface cleaner, using sweet citrus varieties. Jess looks forward to guiding you through these two processes!
