It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.
' x' _9 p4 v. D9 R" j1. 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.* G$ B. b6 C, @
2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.6 N$ |+ e8 G! J1 I3 v$ @
