I’d never heard of pontack until I read about it in the excellent book The River Cottage Preserves Handbook, which is by one of Britain’s master preservers, Pam Corbin. When I began researching this vinegary elderberry sauce, it seems to be an ancient British recipe, dating back at least a few centuries.
- 2 pounds fresh elderberries, or 12 ounces dried
- 4 cups cider vinegar
- 1 pound shallots, minced
- 10 allspice berries
- 1 teaspoon nutmeg
- 2 tablespoons cracked black peppercorns
- 1 teaspoon salt
Take all the elderberries off the stems; the stems are slightly toxic, and you don't want to eat them. A couple are OK, but do your best to remove them all. Take your time, and if you are skilled, you can destem 2 pounds in less than 30 minutes.
- Put the elderberries into a covered casserole or other oven-proof dish with the vinegar and cook at 250°F for 4 to 6 hours. Your house will smell like fruity vinegar during this time, which isn't such a bad thing.
- Pour the cooked liquid through a strainer (to catch all the berries) and into a large bowl. Let the cooked berries cool enough to handle, then, with your clean hands, press as much juice as you can from the berries and into the bowl. You might need to do this in batches.
- Discard the spent berries.
- Pour the sauce into a pot and add the remaining ingredients. Simmer gently for 25 minutes. Strain one more time to remove the spices.
- Return it to the pot and bring it to a boil; let it boil for 5 minutes.
- Meanwhile, get very clean Mason jars or other containers and clean lids, corks or whatever. This sauce is primarily vinegar, so you really don't have to worry too much about it going bad, but you still want clean things to put your pontack in.
- Pour the hot pontack into your containers and seal. Let cool and put in your pantry. Should last at least 7 years. Really. It does.
