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. Onion, thyme and fennel give the syrup its strong, herby flavour.

After cooking, leave the mixing bowl to cool to around 40°C before adding 100 g of honey and stirring it in for 5 seconds at speed 4. This preserves the flavour and aroma of the honey. Then strain the syrup through a fine sieve into a clean bottle.

What onion, thyme and fennel contribute to the flavour

Onion, thyme and fennel give the syrup a strong, herby flavour; honey adds sweetness and a thicker consistency. This recipe is a home remedy, not a medical treatment.

Important information about children and dosage

This recipe is a home remedy and is not a substitute for medical advice. Because it contains thyme and fennel seeds, it is not intended for self-treatment in children under 4 years of age.

Ginger, sage, agave syrup: 3 variations

  • With ginger: Chop a thumb-sized piece of fresh ginger together with the onion. The ginger adds a hot, spicy note.
  • Sage instead of thyme: Use 2 tbsp of dried sage. Sage gives the syrup a strong, tart note.
  • Vegan with agave syrup: Replace the honey with 100 g of agave syrup. The flavour and consistency will change; this version contains no honey.

Refrigerate immediately and use within 2–3 days

Pour into a clean container, refrigerate immediately and, conservatively, use within 2–3 days. A longer shelf life has not been tested for this recipe. Discard if the smell, colour or consistency changes.
