Rehydrating after some midweek madness with homemade lemongrass and ginger water kefir made with coconut sugar. Aside from curing hangovers, kefir is supposed to help the body adapt to a change in the seasons and also bring one's immune and digestive systems back on track. I learnt the basics of this ancient craft in a group class led by Louise K Buckley, Hong Kong's fermenting guru, whose book "Culture your Life" is currently on offer at just 5 USD until the end of the month. Use the code BACK at checkout. Also look out for classes run by Jacqueline Reneé Cohen, one of L Buckley's protégés, kicking off on September 23rd at Sol Wellness.
