How To Clean Spinach Before Freezing It
The best way to clean spinach is to use water and vinegar.
Trim away any thick stems from the spinach.
Fill a big bowl with water and add 2 tablespoons of vinegar.
Put the spinach into the bowl and mix it around with your hand. Let the spinach soak for 30 minutes.
Remove the spinach from the bowl and put it into the colander/strainer. Rinse it under cold running water.
Lay the spinach leaves on a towel and pat them dry with another cloth.
