Times are estimates; follow the doneness cues in the method. Quantities refer to harvested food, never planting seeds.

Ingredients

  • 120 g cultivated watercress, washed
  • 400 g potatoes, peeled and diced
  • 1 onion, diced
  • 1 tbsp olive oil
  • 800 ml vegetable broth
  • 100 ml cream
  • 1/4 tsp salt

Method

  1. Soften onion in oil 5 minutes. Add potatoes and broth; simmer 15 minutes until potatoes are soft.
  2. Add watercress and simmer 2 minutes until wilted.
  3. Blend with an immersion blender, stir in cream and salt, and warm gently.

Storage

Cool cooked food promptly in shallow containers and refrigerate within 2 hours at 4°C or colder. Use within 2–3 days, or freeze promptly where texture allows. Refrigerate raw prepared salads and dairy sauces promptly; dress salads just before serving. Reheat cooked leftovers to 74°C.

Grow the main ingredient

Start with the named variety in the Casa Verde seed shop. Growing time, harvest size and flavour depend on your conditions; this recipe uses the harvested crop.

Other harvests to try

Choose similar tenderness and prepared weight; adjust cooking to the cut size. Colour and flavour will change. For peppers, check heat first: hotter varieties are not a gram-for-gram swap.
