Oh no: uncooked potato

elevated by yesterday's success with cooking, we decided to make food today also.. but we did not cook potato properly... actually we left potato in cooker for 10 min.. whereas it shld have been around 15 mins or so.. i do not know.. some of you might be knowing the answer..let me know if u wish..
However, we ate the food cooked..and 15 after eating it started paining in my stomach.. not much pain but i can feel it.. and it is paining while i am writing this.. it has been around 30 min since we took dinner..

good nite folks..time to work
