Home canned blueberries with Grand Marnier

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

Ingredients

• blueberries
• water
• Grand Marnier

Instructions

1. Wash berries in batches of 1 or 2 litres (quarts) at a time.
2. Drain, and get any stems off.
3. Have a pan of water boiling.
4. Add the berries in small batches at a time so that the water will come back to the boil quickly.
5. Let the berries boil for 30 seconds, then fish out of pot immediately with slotted spoon or sieve.
6. Repeat until all berries are blanched.
7. Divvy berries out amongst jars, leaving 2 cm (1/2 inch) headspace.
8. Add 1/2 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.
9. Divvy blanching juice out amongst jars, leaving 2 cm (1/2 inch) headspace.
10. If short of canning liquid, top jars up with boiling water from a kettle.
11. Debubble, top up with more liquid as required to retain headspace.
12. Wipe jar rims.
13. Put lids on.
14. Process jars in a water bath or steam canner for 15 minutes regardless of size chosen; increase time as needed for your altitude.

Recipe Notes

Start out with only a small amount of blanching water, just enough to cover the berries, because as you blanch the berries they will release juice and the amount of liquid will increase. That way, you end up with purer and less watered-down juice to use for packing the berries in.

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.
