So I've a problem , attimes I don't like the taste of the food I cook or it doesn't look as
Presentable as I'll likeit to. I try to put everything proportionally from salt,maggi to pepper etc but still like 3 out of 10 times it won't taste nice,especially rice!! (jollof,fried etc).I've been cooking for like 8yrs now so it's definitely not about me being new. I try to do everything the way I see my mother and other good cooks do,but I don't get so lucky.So,what do you people do when the food does not taste or look like you want it to?Is there any cooking secret I should know or something very helpful (spice,methods) etc.Might be getting married in a year or 2,don't want to go to my husband's house cooking rubbish,so please help me as much as you can....thank you

Trial and error, trial and error, trial and error.
Since its marriage you're looking to build your skill towards I suggest bonding with your fiance's mother during the engagement. Your cooking would always get compared to her's so why not learn to mimic her's?
In the case of going through multiple engagements repeat the step always without fail; all men and mother inlaws're different but all men compare your cooking to their mother's.
