Home-canned mushrooms are delicious. Tinned mushrooms from the store are metallic tasting and rubbery-textured in comparison.
But home-canned are really a gourmet-level product to have on hand, and with cognac in the jar: delicious.
Serving suggestions: use in creamed mushroom sauces for crêpes, etc.
This procedure completely follows the tested USDA pressure-canning process for home-canning plain mushrooms, and just adds a bit of cognac to the canning liquid for flavouring.
The downside is, they are less flexible when you go to use them. The cognac taste doesn’t suit everything!
Quantities of mushrooms needed
Numbers are approximate guidelines.
On average, as a very rough guideline, expect to need about 1 kg (2 lbs) of mushrooms per ½ litre (US pint) jar of canned mushrooms.
- 6 ½ kg (14 ½ lbs ) of mushrooms = 9 x ½ litres (US pints) canned mushrooms
Jar size choices: Either quarter-litre (½ US pint) OR half-litre (1 US pint)
Processing method: Pressure canning only
Headspace: 3 cm (1 inch)
Processing pressure: 10 lbs (69 kPa) weighted gauge, 11 lbs (76 kpa) dial gauge (adjust pressure for your altitude when over 300 metres / 1000 feet)
Processing time: Either size jar for 45 minutes
Home-canned mushrooms with cognac
- Trim off and discard stem ends and any discoloured parts.
- Soak in a sink, or large pot or bowl, full of cold water. Soak for 10 minutes to loosen any dirt.
- Refill sink with fresh clean cold water, and wash.
- You can leave small mushrooms whole; cut large ones up.
- Put mushrooms in a pot with water, bring to a boil and boil 5 minutes.
- Pack into quarter-litre (½ US pint) or half-litre (US pint) jars.
- To a quarter-litre (½ US pint) jar add 1 tablespoon cognac; double that for the half-litre (US pint) jars.
- Leave 3 cm (1 inch) headspace.
- Top up with clean boiling water (such as from a kettle, for instance), maintaining headspace.
- Debubble, adjust headspace.
- Wipe jar rims.
- Put lids on.
- Processing pressure: 10 lbs (69 kPa) weighted gauge, 11 lbs (76 kpa) dial gauge (adjust pressure for your altitude when over 300 metres / 1000 feet)
- Processing time: Either size jar for 45 minutes.
Processing guidelines below are for weighted-gauge pressure canner. See also if applicable: Dial-gauge pressures.
|Jar Size||Time||0 to 300 m (0 - 1000 feet) pressure||Above 300 m (1000 ft) pressure|
|¼ litre (½ US pint)||45 mins||10 lbs||15 lb|
|½ litre (1 US pint)||45 mins||10 lbs||15 lb|
How to pressure can.
When pressure canning, you must adjust the pressure for your altitude.
