Chef Notes & Tips

Use the peeled cauliflower core in the base: it has excellent flavour and reduces waste.

Ingredient choices: Wash leek layers thoroughly and use cauliflower core only where tender enough after cooking. Slice dense core pieces smaller than florets. Toast hazelnuts carefully and remove loose skins if desired.

Cooking control: Soften leek without heavy browning for a pale soup. Simmer cauliflower until fully tender, then blend with suitable equipment. Adjust stock and cream before tasting lemon and nutmeg.

If something goes wrong: A grainy soup usually needs more cauliflower cooking or blending. Excess nutmeg can dominate the mild vegetables. If the finish is heavy, test a little lemon before adding more cream.

Ingredient Substitutions

• ↔ Unsweetened oat cream can replace dairy cream; toasted almonds may replace hazelnuts.

Food Safety & Doneness

Wash produce and use clean utensils. Keep perishable ingredients refrigerated. Refrigerate cooked food in shallow containers within 2 hours, or within 1 hour when the surroundings exceed 32°C. For hot soup, use an immersion blender with its head submerged, or cool sufficiently before using a blender approved for warm liquids. Never seal hot soup in a closed cup blender.

Serving & Plating

Serve with chopped toasted hazelnuts added at the last moment. Identify nuts and dairy clearly, including the garnish.

Storage

Refrigerate promptly in shallow covered containers at 4°C or below and use within 3 days. Reheat only the portion needed to at least 74°C throughout. Discard food left unrefrigerated for more than 2 hours, or 1 hour above 32°C.
