1 U* Q5 a! F, p8 @/ W V1. 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.
3 ~' s. `2 g$ E3 Z0 ~ v2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.7 |, z5 i9 I. x3 ?" P
Next day, more bubbling activitiy everywhere. slight alcohol smell.
2 L$ K+ h2 M' s; ?! G' vin 3rd day rice broke down from it's shape, stronger alcohol smell, truns darker color
