The fizzing was notice that the house was about to reek. When we heard that sound - like someone trying to ease open a soda bottle without spilling any foam - we'd beat feet out of range.
I take it horseradish is easy to grow? Can you eat it in its natural state?
A friend of mine has a husband who's pretty inventive in the kitchen, and he made breakfast Sunday morning that was served on some sort of big leaf that he says is from a Cuban plant. It's sorta peppery and sorta has a licorice taste, but not much of one - more pepper. I liked it a lot.
It apparently grows like a weed.........to harvest it you get a hoe or trowel and dig straight down to cut the root. The edible part is the root. Just cut out a chunk of the root - it doesn't kill the plant - then wash it, peel it and grate it. But be aware, if you're senstive to cutting onions, this is a heck of a lot worse.
You would have to mention the leaf - now I can't think of the name of it.......LOL!!!
