Pickled red grapes

It might be more unusual to see fruit instead of vegetables in a pickling liquid, but we pickle lots of fruit and find the vinegar offsets its sweetness beautifully.

These pickled grapes go well with soft cheese – try them on top of baked ricotta – and they make an interesting addition to a salad or roasted meat dishes (just add them to the roasting tin about 5 minutes before the end of the cooking time). Other fruit that can be successfully pickled include quinces, pears, plums or sugar plums, rhubarb and cumquats. 

Ingredients

• 500 ml (17 fl oz/2 cups) red wine vinegar
• 440 g (15½ oz/2 cups) caster (superfine) sugar
• 6 allspice berries
• 12 black peppercorns
• 3 slices ginger
• 1 kg (2 lb 4 oz) red grapes 

Makes: 2-3 x 500 ml jars

Instructions

First sterilise your jars (see Note). 

Make a brine by putting the vinegar, sugar and 500 ml (17 fl oz/2 cups) of water in a small non-reactive saucepan over low heat. Stir until the sugar has dissolved, then increase the heat and bring to the boil. Take off the heat.

When the jars are cool enough to handle, put 2 allspice berries, 4 peppercorns and a slice of ginger into each one. Carefully pack in the grapes, then let them soften in the hot brine for a few minutes; they will shrink and you may be able to pack in some more. Remove any air bubbles by gently tapping each jar on the work surface and sliding a butter knife or chopstick around the inside to release any hidden air pockets. You may need to add more grapes or brine after doing this (the liquid should reach about 1 cm/½ in from the top of the jar). Wipe the rims of the jars with a clean cloth and seal, then heat-process for 15 minutes (see Note).

Store in a cool, dark place for at least a month before using. Unopened jars will keep for up to 12 months; once opened, refrigerate and use within 3 months.

Notes

• Use good-quality jars made of thick glass, such as those available from kitchen supply stores. Cheap jars from discount stores often have thin glass, which tends to become brittle at high temperatures.

•To sterilise jars or bottles, give them a wash in hot soapy water and a good rinse, then place in a cold oven. Heat the oven to 110ºC (225ºF/gas mark ½) and, once it has reached temperature, leave the jars in the oven for about 10 minutes or until completely dry, then remove them carefully.

• To sterilise the lids, place them in a large saucepan of boiling water for 5 minutes, then drain and dry with clean paper towels or leave them on a wire rack to air dry. Make sure they are completely dry before using.

• Also called water bathing or canning, heat-processing uses heat to stop the growth of bacteria. Treating your preserves in this way has two benefits: it lengthens their shelf life, and it ensures the jars or bottles are sealed correctly. 

Get the biggest pan you have, such as a stockpot and put it on the stove pot. Lay a folded tea towel in the bottom of the pan, then sit your jars on the tea towel, taking care not to cram them in and keeping them clear of the sides of the pan. (All these measures are to stop the jars from wobbling around and cracking as the water boils.) Roughly match the water temperature to the temperature of the jars (to help prevent breakages form thermal shock), then pour in enough water to cover the jars, either completely or at least until three-quarters submerged. Bring to the boil over medium heat. The heat-processing time given in the recipe starts from boiling point.

You may expect one or two breakages when you’re starting out – the worst that can happen is that the remaining jars will swim in pickles or jammy water for the rest of the processing time. Just keep going, then take the surviving jars out at the end and give them a wipe down. If they all break, you have our permission to have a gin and a lie-down! 

Once the heat-processing time is up, the lids should be puffed up and convex. Carefully remove the hot jars from the water. If you’ve bought some clamps, now is the time to use them, or you can use oven mitts and a thick cloth to protect your hands. Line your jars up on the bench and let them sit overnight. As they cool, a vacuum will form inside each jar and suck down the lid, sealing them securely. In the morning, the lids should be concave: either get down to eye level with the top of the jar to check for the tell-tale dip in the lid, or lay a pencil across each lid to show the cavity below it. If you have concerns about the seal of any of your jars (sometimes a couple of jars fail to seal correctly), store them in the fridge and use their contents within a few weeks.

Cook's Notes

Oven temperatures are for conventional; if using fan-forced (convection), reduce the temperature by 20˚C. | We use Australian tablespoons and cups: 1 teaspoon equals 5 ml; 1 tablespoon equals 20 ml; 1 cup equals 250 ml. | All herbs are fresh (unless specified) and cups are lightly packed. | All vegetables are medium size and peeled, unless specified. | All eggs are 55-60 g, unless specified.
