  • 2 tablespoon olive oil
  • 300 grams celery fresh, with any hard strings removed, chopped
  • 200 grams white potatoes chopped
  • 1 medium zucchini chopped
  • 1 teaspoon mixed herbs low histamine compliant herbs
  • 500 mls vegetable stock
  • 100 mls non-dairy milk almond, oat or coconut
  • salt to taste
  • 1 garlic clove optional, or garlic powder
  • teaspoon sesame seeds optional
  • mint leaves optional


  • Heat the olive in a large saucepan and add the celery, potatoes, zucchini and garlic (if using), salt and herbs. Add a splash of water to stop the potatoes from sticking. Cook for about 15 minutes, stirring frequently and adding more water if necessary.
  • Make the stock and pour into the pan and bring to the boil. Reduce to a simmer and cook for about 20 minutes, stirring occasionally.
  • Turn the heat down or turn off completely, and blend the soup with a hand-blender. Add the milk, give it a good stir or blend again. Return to the heat to warm up if needed. Add more salt to taste, and the sesame seeds and mint to garnish, if using.
  • Serve immediately and enjoy!


  • If the potatoes are sticking to the pan initially, add a touch of water.
  • You can either use an immersion blender or transfer batches to a food processor to blend.
  • Use a non-dairy milk that works best for you. The type will very slightly change the taste of the soup.

All ingredients in this recipe score a '0' on the SIGHI scale with the exception of:
  • almonds in the almond milk, which score a '1' - you could use oat milk as an alternative.
  • garlic, which scores a '1' - this can be omitted if you are sensitive to it. The SIGHI list states this is usually well-tolerated after cooking.
  • sesame seeds, which score a '1' - this is a garnish and can be omitted. Note that sesame is potential allergen.
  • vegetable stock varies depending on the brand used, and branded products are not rated on the SIGHI list so check for problem ingredients.
  • check that the mixed herbs that you use are low histamine ones.
