Do you know what this is?
It's frozen cilantro.
We use fresh herbs frequently, and I have a trick for keeping them fresh a little longer, but there are times when we can't use it fast enough no matter what. (There are also times when fresh herbs are on sale and I want to stock up at a low price...)
How to take advantage of sales? Wash and chop your herbs, place them in a sandwich baggie and fill with enough water to cover the herbs. Pop into the freezer until you're ready to use. The water keeps the herbs green and fresh looking and seals out any air that might get to them.
Today I'm making chili. I took a baggie of my frozen cilantro...
Sliced open the baggie, took out my frozen little brick of fresh cilantro... and popped it right into the simmering pot of chili.
In addition to saving money, it's a time saver too. Sometimes I get a wild, organizational hair and prep a bunch of different herbs this way and then can easily drop them into soups, sauces, etc whenever I need.
Easy. I love that.
