let me share some tips for buying water melon
find the one with less physical damage i.e no holes , no deep cut marks, shape looks normal..
the most imp thing to check is to find one with darkish/brighter yellow mark on melon.. the better is mark..the more better it turns out..because it shows how good its cooked on ground before plucking
things to avoid " Never ever ask Faruuuit wala to cut it open and check it ..... the knifes they use are full and exposed to all kind of bacteria's and water melon is 80% water... imagine it getting cut with such knife and un washed melon with all kind of dirt on it and it gets inside after cut ...
the reason people suffer serious diarrhea and serious health conditions with melon is due to this very reason.. it multiplies bacteria as its all 80% water
its always advice to wash melon 1st nice and through , then clean your knife , select clean surface and then go ahead.
melons shld be consumed as early as possible after cutting and never kept on room temp after cutting..always refrigerated but not for long
