Add a splash of Grand Marnier to home canned blueberries.
It gives the berries a little bit of citrus flavour, as well as a bit of warmth.
Very nice as gifts.
Quantities of blueberries needed
Numbers are approximate guidelines.
On average, as a very rough guideline, expect to need per jar:
- about 175 g (1/2 lb) of blueberries per 1/4 litre (1/2 US pint) jar of canned blueberries;
- about 375 g ( 3/4 lb) of blueberries per 1/2 litre (US pint) jar of canned blueberries;
- about 750 g (1 3/4 lbs) of blueberries per 1 litre (US quart) jar of canned blueberries.
On a larger scale:
- 5 1/2 kg kg (12 lb) of blueberries = 7 litres (US quarts) canned blueberries
- 3 1/2 kg (8 lbs ) of blueberries = 9 x 1/2 litres (US pints) canned blueberries
- 1 x 24 quart crate blueberries = 16 kg (36 lbs) = 18 to 24 litres (US quarts) canned blueberries
1 litre (US quart) whole, fresh blueberries = 750 g (1 1/2 lbs), whole fresh
4 litres (US quarts) fresh blueberries = 3 litres (US quarts), blanched for 30 seconds
1 litre (US quart) blanched blueberries = 1 kg (2 1/4 lbs) of blanched berries

- Grand Marnier
- Wash berries in batches of 1 or 2 litres (quarts) at a time.
- Drain, and get any stems off.
- Have a pan of water boiling.
- Add the berries in small batches at a time so that the water will come back to the boil quickly.
- Let the berries boil for 30 seconds, then fish out of pot immediately with slotted spoon or sieve.
- Repeat until all berries are blanched.
- Divvy berries out amongst jars, leaving 2 cm (1/2 inch) headspace.
- Add ½ tablespoon of Grand Marnier per quarter-litre (1/2 US pint / 1 cup / 8 oz) jar OR 1 tablespoon per half-litre (1 US pint / 2 cup / 16 oz) jar OR 2 tablespoons per litre / quart.
- Divvy blanching juice out amongst jars, leaving 2 cm (1/2 inch) headspace.
- If short of canning liquid, top jars up with boiling water from a kettle.
- Debubble, top up with more liquid as required to retain headspace.
- Wipe jar rims.
- Put lids on.
- Process jars in a water bath or steam canner for 15 minutes regardless of size chosen; increase time as needed for your altitude.
Instead of Grand Marnier, you could use Cointreau, or Triple Sec.
The USDA also gives pressure-canning and raw-pack alternatives for canning blueberries.
By the time, though, that you heat and vent a pressure canner, run it and then cool it down, it would take longer than simple steam canning.
And note that for sugar-free canning of fruit, raw packs are not generally advised.
How to water bath process.
How to steam can.
When water-bath canning or steam canning, you must adjust the processing time for your altitude.
