Method

You’ll need: oven · baking tray · chopping board · knife · grater

1. Preheat the oven to 220 °C (200 °C fan) and line a baking tray with baking paper. Grease the paper lightly with olive oil, ghee or avocado oil.
2. Finely chop the cauliflower and cook until soft. Then put it in a clean tea towel and squeeze out thoroughly so that as little liquid as possible remains.
3. Mix the cauliflower with the egg, grated cheese, salt, black pepper and nutmeg to a mixture you can shape. Press it out thinly on the baking paper into a flat oval and pre-bake at 220 °C for 15–20 min, until the base is golden brown.
4. Meanwhile, stir the soured cream with a little black pepper until smooth. Slice the red onion into thin rings and chop the chives.
5. Spread the pre-baked base with the soured cream and top with the onion rings and diced cured turkey. Bake at 220 °C for another 8–10 min, until the edge is well browned and the topping is hot.
6. Scatter with fresh chives and serve warm straight away.

Good to know

Flammkuchen can be light and properly savoury too. The cauliflower base turns surprisingly crispy and makes the whole thing pleasantly hearty.

Swaps

Lean diced cured turkey → smoked salmon or organic turkey bacon from high-welfare farms (less processed; in pregnancy, bake the smoked salmon until piping hot) Soured cream → crème fraîche or Greek yoghurt (10% fat) (creamier or more protein, depending on what you're after) Grated cheese → buffalo mozzarella or Alpine cheese (such as Gruyère), freshly grated (often a shorter ingredients list, stronger flavour) Red onion → leek or spring onions (milder)

Allergens

Contains egg and milk. Onion can be rather irritating for sensitive children or people with a sensitive gut, and in pregnancy only eat the cured turkey once it has been heated until piping hot.

Frequently asked questions

What nutrients are in the cauliflower base?

Cauliflower provides vitamin C, folate, potassium and fibre. The egg and cheese add protein, calcium, phosphorus and vitamin B12.

Raw or baked onion – which is milder?

Baked onion is often perceived as milder than raw. But it still contains fermentable carbohydrates, which can cause wind in people with a sensitive gut.

What does soured cream bring nutritionally?

Soured cream mainly provides fat, plus smaller amounts of vitamin A and calcium. It makes the topping creamy, but because of its fat content it's more an ingredient for enjoyment than for lots of nutrients.

What does the egg do in the recipe besides binding?

The egg provides protein, vitamin B12, selenium and choline. Choline is an essential nutrient that people don't often talk about.

What do the cured turkey cubes bring nutritionally?

They bring protein and, depending on the type, iron and zinc. At the same time, processed meat products often contain more salt, so it's worth using them mindfully.
