The Salt Water Test

Two hundred tiny pockets in one head of broccoli. Here is the test, properly — how long, how much salt, and what it does not catch.

You commented ROOTS because I dunked a broccoli in salt water on the video and you watched the little dark things swim out of it. Here it is, written down properly.

The test, exactly

Cold water. A real handful of coarse salt — not a pinch, close to a quarter cup for a full bowl. Push the head down florets-first so the water gets into every pocket, and give it ten to fifteen minutes. Longer than that and you start pulling flavour out of the broccoli along with everything else.

If nothing comes loose in that time, the broccoli is good to cook. If something does, you will see it drift out on its own — do not scrub, do not shake the bowl, just let the salt do the work.

What two hundred tiny pockets means

A head of broccoli is not smooth. Under the surface it is built out of hundreds of small hollow florets, and every one of them is a hiding place an insect can lay eggs in that a rinse under the tap will never reach. Cold water alone will not pull anything out of those pockets — it takes the salt to do it. That is the whole trick, and it is the only part of the video worth remembering.

What it does not catch

I would rather tell you the limit than let you think one soak fixes everything.

What to watch for beyond the bugs

  • Pesticide residue. Salt water does not touch what was sprayed on the leaf before it left the field. If that is your worry, a short soak in water with a splash of vinegar does more, and even that is not a guarantee.
  • Wax coatings, on cucumber and some apples, are put there on purpose to keep the skin from drying out — salt will not lift it either. Peel if it bothers you.
  • This is not a wash for bacteria. Ten minutes in salt water is not the same job as washing your hands before you cook. Rinse everything after, salt water or not.

The rest of what comes home from the market

Broccoli is not the only thing worth ten minutes in a bowl.

What happens next

This is not a remedy, so it does not belong on the same shelf as the roots and the teas I write down here. It is one of the things I am collecting for What We Kept — the practices, not the cures. How the old people checked what came into the house before it went anywhere near a pot.

Give thanks.
