Kefir Ice Cream Recipe
This is a new and improved recipe, based on a traditional gelato that I’ve altered so that the microbial activity of the kefir can be preserved.

Dr. Caroline Gilmartin
💖 Favorite Ferments: Milk kefir is my absolute top ferment and I take it with me wherever I go, yes on holiday, everywhere. Then Kimchi because who doesn’t love kimchi? Then Kombucha.
💡 Fermentation Tip: People have been fermenting for centuries – don’t forget you’ve got your senses to guide you – sight, smell, touch, taste and common sense are all invaluable to the fermenter, whether just starting out or a seasoned old timer.
🏝️ Desert Island Tools: My ikea straining funnel, my tap dispenser, and a pH meter!
Dr. Caroline Gilmartin
Home Fermentation Specialist

Introduced to milk kefir over 15 years ago, Dr. Caroline Gilmartin never imagined it would spark a new career.

She went on to run her own fermentary, selling everything from kombucha and kimchi to miso, while teaching fermentation to audiences across the UK.

Caroline is the author of two books, Fermentation: A Practical Approach and Vinegar, and now serves on the advisory board of the UK Fermenter’s Guild. She also runs an online business providing fermentation cultures and support for home fermenters.

Passionate about making fermentation accessible, Caroline regularly hosts live sessions on Instagram and Substack, demonstrating how easy it is to make kefir, kombucha, or kimchi at home and inspiring others to ferment with confidence.
