Spinach soup is loaded with iron and vitamins and comes together in twenty minutes. Its bright green colour is the first thing people judge — and getting there is purely a matter of timing.

## Ingredients

- 600 g — fresh spinach
- 1 — onion
- 1 — potato
- 4 cloves — garlic
- 4 cups — vegetable stock
- 1/2 cup — cooking cream
- 3 tbsp — butter
- 1/2 tsp — nutmeg
- 1 tbsp — lemon juice
- 1 tsp — salt
- 1/2 tsp — white pepper

## Method

1. **Build the base** — Melt the butter and cook the onion for **6 minutes** until translucent, then add the garlic and nutmeg for **30 seconds**. Softened onion gives the soup its sweet backbone.
2. **Simmer the potato** — Add the diced potato, stock and salt, and simmer **15 minutes** until the potato is completely tender and crushes under a fork.
3. **Spinach in the last two minutes** — Add the washed spinach and stir for **two minutes only**, just until it wilts while still vivid green. **Do not let it boil** — that is what turns it dark.
4. **Blend fast** — Take the pot off the heat **immediately** and blend with a stick blender for **one minute**. Every extra minute on the heat costs you a shade of green.
5. **Cream over low heat** — Return to the **lowest heat**, stir in the cream and white pepper, and never let it boil. Boiling splits the cream and darkens the green.
6. **Lemon at the very end** — Add the lemon juice **after the pot is off the heat**. Acid over heat accelerates chlorophyll breakdown; off the heat it only lifts the flavour.

## Tips

- Spinach in the last two minutes only — long cooking is what blackens it.
- Lemon after the heat, not before — acid over heat darkens the colour.
- For an even brighter colour: shock the wilted spinach in ice water before blending.
- The potato provides the body; the cream is there for flavour only.

## FAQ

### Why does my spinach soup turn dark?
The spinach cooked too long. Sustained heat breaks chlorophyll down. Add spinach in the last two minutes only, pull the pot off the heat at once, and blend quickly.

### Can I use frozen spinach?
Yes, but thaw it and squeeze the water out first. Frozen spinach is blanched before freezing so its colour starts duller — the result is acceptable but not as vivid as fresh.

### How do I get the brightest possible green?
Use an ice-water shock: once the spinach wilts, lift it out with tongs, plunge it into iced water for 30 seconds, then return it for blending. That stops the cooking instantly and fixes the green.
