Chop the onion, add the herbs, cook for 10 minutes: the syrup really is that simple

Halve 1 onion and chop for 5 seconds at speed 5. Then add 250 g water, 2 tbsp of dried thyme and 1 tbsp of fennel seeds to the mixing bowl and cook for 10 minutes at 100°C at speed 1. As the onion cooks it releases essential oils, the thyme helps to loosen mucus and the fennel seeds soothe the throat.

After cooking, leave the mixing bowl to cool to around 40°C before we add 100 g of honey and stir it in for 5 seconds at speed 4. Why wait until it has cooled? Heat above 40°C destroys the enzymes in the honey that are responsible for its soothing effect. Then strain the syrup through a fine sieve into a sterilised bottle.

Why onion, thyme and fennel work so well together

The combination is no coincidence. Onions contain sulphides that help to reduce swelling in the mucous membranes. Thyme contains thymol, which has antibacterial properties and eases the urge to cough. Fennel seeds help to loosen stubborn mucus. Together with honey as a natural cough soother, the result is a syrup that gives noticeable relief for mild to moderate coughs.

3 x 2 teaspoons a day: the right dosage

For adults and children over 12 years we recommend 3 x 2 teaspoons a day. Children between 4 and 12 years take 3 x 1 teaspoon. The syrup is not suitable for children under 1 year because honey is not recommended for infants. For a persistent cough, fever or difficulty breathing, always consult a doctor.

Ginger, sage, agave syrup: 3 variations

  • With ginger: Chop a thumb-sized piece of fresh ginger together with the onion. The ginger warms from the inside and boosts the mucus-loosening effect.
  • Sage instead of thyme: Use 2 tbsp of dried sage. Sage works especially well for sore throats and throat inflammation.
  • Vegan with agave syrup: Replace the honey with 100 g of agave syrup. The herbs keep all their properties; only the honey effect is lost.

Sterilised bottle, fridge, keeps for 2 weeks

Before filling, sterilise the bottle with boiling water. Store the finished cough syrup in the fridge and use it within 2 weeks. As it contains no preservatives, it does not keep as long as products bought from a pharmacy. We therefore always make just one batch at a time and prepare a fresh one when needed.
