My mother taught me this trick, and it's one worth knowing if you're a cilantro fan. The picture here was taken 2 weeks after I purchased this bunch of cilantro at the store--and it looks perfect!
Here's what you do:
- Fill a small glass (wide enough for stems to fit easily, but short enough not to interfere with the leaves much) with water.
- Trim cilantro stems about 1/2-inch.
- Place the bunch in water like you would with cut flowers.
- Place plastic bag from the store loosely over the top, folding up the bottom edge if necessary to still allow air flow (see small picture).
- That's it!
