This was my failure
It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.
1 ~# C9 B/ D5 [- u8 _ L* y( ]+ v0 R* i1. 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.1 y% R- T, K& h( ^+ U
2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.% d8 h4 v4 ~9 J
Next day, more bubbling activitiy everywhere. slight alcohol smell.6 J9 q2 {/ f6 }# L7 p6 J* k
in 3rd day rice broke down from it's shape, stronger alcohol smell, truns darker color
! [6 Z3 u% w8 |# d4th day very little bubbling, shaked jar hoping to improve activity, (this could be the mistake)( w+ N1 B8 L6 V* Z' w& }* x/ z; Y$ U
