For cooking it would be great to have a self made sub-product from ginger, but:

  • if refrigerated, you get rather something like thin ginger juice
  • I don't like the Asia shop variant where they put lots of salt

Any other ideas or well established experiences?

The goal: to find the optimum between "as long as possible" and "as fresh as possible".

  • I didn't notice before answering, do you actually mean 'preserve' (like salt/can/pickle/ferment/etc.) or do you mean where to keep it actually fresh (as I perhaps misread) for as long as possible? – OJFord Nov 27 '19 at 17:57
  • hi - thank you - optimum of both, actually. – J. Doe Nov 27 '19 at 18:57
  • Maybe my answer here will help. This is one way to freeze it: cooking.stackexchange.com/questions/38224/… I also concur with freezing the whole hand and grating when you need it. – Jolenealaska Nov 28 '19 at 20:13

If your goal is longer term preservation, freezing is one of the easiest methods and what I tend to do on occasions when I've bought a lot of ginger at once (for whatever reason). While you'll lose a little flavor with freezing, when used in cooking, I find it still works well and is often difficult to distinguish from fresh. And it's quite convenient: you can actually pull out a frozen piece of ginger, grate off what you need, and just put the rest back in the freezer.

As a side benefit, peeling and grating frozen ginger can actually be a bit easier than doing the same to fresh ginger. If you need chunks of ginger, though, you'll need to let it defrost a bit first (or, alternatively, cut before freezing if you have a standard recipe you want to use it for).

    You can also freeze pureed ginger if you have a suitable machine and that's how your use it. Ice cube trays allow you to defrost sensible quantities. Garlic+ginger puree is also good to have in the freezer. I suggest a distinctive ice cube tray (with a lid to avoid drying out) as you'll never quite get the flavour out of the plastic – Chris H Nov 28 '19 at 8:01
  • @Athanasius I'm sorry. You don't need to react so hostile. I'm not a native speaker and "ginger root" would be considered wrong in my language. – Belle Dec 2 '19 at 8:57
  • @Belle-Sophie: My apologies. No need for you to apologize. I was not intending to be hostile, just explaining my reasoning. (And also pointing out the absurdity in many food names, which don't accord with botanical classification.) This is a difficulty in a text-based medium that doesn't express tone well. I thought you were expressing a (pedantic) distinction that isn't necessarily relevant to the way English uses the terms in cooking. Again, I apologize if my comment was overbearing -- I really was trying to point out the problems in naming foods, not to attack you. I'll delete my comment. – Athanasius Dec 2 '19 at 14:04

Like garlic, ginger is best stored cool but not refigerated, or it will rapidly dry out.

It will still dry on exposed faces of course, but you can just slice thinly off until you come back to usable flesh.

It may also start to resume growth. That's no problem, if anything I'd say it's good - it's indicative of freshness and good conditions.

A small pot (you can also find them sold specifically for garlic, and perhaps ginger - sometimes oven-safe too) on the side is ideal, failing that just any ramekin/bowl/shelf/whatever - a pot would just help maintain a stable temperature and avoid light.

I find it keeps for around a month at room temperature, longer cool. You may have better luck in the fridge if it's easier to keep sealed there than cool without.

Plant it. That preserves it pretty much forever. And you get more over time! You can keep it as a houseplant. Water it every month or so. It can be harvested whenever you like, you don't even need to wait for it to grow or mature.

I bought a piece of ginger, used what I needed and cut the remaining piece into 1-inch (2.5-3cm) pieces. I soaked the to-plant pieces overnight in warm water and planted them in pots (about 6 inches/15 cm deep and 8 inches/20 cm apart). If they have sprouting bits, put them on the top. Water them after planting and about once a month after that. They like sunlight, but not direct sunlight. Mines were really happy in front of my north-facing window.

If you want to use your ginger, just take it out of the ground (whether it sprouted or not). If it has grown more rhizomes (it takes about 4 months to do so), you can plant part of it back. Just give it a day to heal and perhaps another overnight soak before you do so.

You can find quite a bit of information about growing ginger on our sister site gardening.

Freeze it.

Put the ginger root in the freezer. When you want some ginger just put the frozen root in the sink hole and turn the tap on a trickle for a few minutes. The outside will defrost first while the inside remains frozen. Slice off the defrosted outside and put the frozen core back in the freezer until next time.

Bonus: There is no need to peel the ginger.

Note: This is the sink/plug hole

  • What do you mean by "the sink hole"? – Sneftel Nov 29 '19 at 16:26
