I keep cilantro fresh this way, take an empty bucket of yougurt put some water in it put cilantro as it is in the bucket as its bottom part is dip in water then cover the upper part with plastic bag loosely as it covers the cilantro and it also prevents cilantro from extra cooling effect. I use same plastic bag in which I buy cilantro form store i.e thinly plastic bag. In this way freshness stays longer.
thank u so much jias..i tried this and my dhanya is still so fresh...May Allah bless u..thankx again:)
