Can this be frozen? I wouldn't be able to use this up in just one week.
Agreed. I'd like to know this as well!
Yes, this can definitely be frozen. You might run into slight fading in color over a longer time period and after thawing, but other than that there should be no difference in flavor/texture. I've frozen this in small portions (deli containers, ice cube trays) for up to a month with good results
