This was my failure
It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.& C) I* o1 ~8 K/ t
1. wash everything with broiling water, soak glutine rice overnight , using a bowl, cook inside microwave cooker ,( my rice cooker not easy to clean to oil-free stage), rice was properly cooked ( similar to sticky rice in dimsum restaurant ), left at table to cool down to same temp as back of hand, stir occaionly, sprinkle and mix 1 flat teaspoon of wine yearst ( white color, look like the fruit of lychi ), pour content into a jam jar , half full, put a piece of ceram wrap over jam, screw cap , put jar inside cupboard.
. @! |5 ^: J2 ?1 ]( N2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.8 [3 d6 k8 W6 K9 B
Next day, more bubbling activitiy everywhere. slight alcohol smell.
