Make a batch of these immune-boosting shots to prevent a cold from ruining your Christmas

Opt for fresh, organic produce to maximise benefits – and if one ingredient is unavailable, just double up one of the others.

Makes 6 x 50ml shots
2 tbsp chopped garlic
2 tbsp chopped onion
2 tbsp grated fresh ginger
2 tbsp grated horseradish root
2 tbsp chopped cayenne pepper (or any other chilli)
350ml raw apple cider vinegar

1 Pile the garlic, onion, ginger, horseradish and pepper into a 350ml lidded sterilised jar. (To sterilise, wash it in hot soapy water, dry with a clean cloth, then place in a 200C/Fan 180C/ 400F oven for 10 mins.)
Fill the jar with raw apple cider vinegar, close the lid tightly and shake.
2 Store in a cool, dark place, shaking at least once a day for two weeks.
3 Filter the tonic through a clean piece of muslin, pour into a sterilised bottle. Take a 50ml shot three times a day (on an empty stomach) as soon as you feel the symptoms of a cold. It will keep at room temperature for up to six months.
