3 large eggs
6 tbsp. low-fat cottage cheese
3 spring onions (scallions), sliced
few sprigs of dill, roughly chopped

2. Put the spinach in a colander in the sink and pour over a kettle of boiling water, then leave to drain. When cool enough to handle, squeeze as much liquid as you can from the spinach, then roughly chop.
3. Beat the eggs and season well. Marble through the spinach, cottage cheese, spring onions, dill and a generous grating of nutmeg. Divide the mixture between the muffin cases. Bake for approx. 25 minutes or until just set. Leave to cool a little before removing from the tin.
Nutmeg is thought to have been imported into Europe during the 12th Century by Arab merchants. But by 400 years ago it had become the most valuable spice in the world.
In the 17th Century, displaying a bowl of nutmeg in your home was a sign of immense wealth, says Giles Milton, author of history books including Nathaniel's Nutmeg, an account of English adventurer Nathanial Courthope.
"Nutmeg was the ultimate luxury," says Mr Milton. "Of all the spices, nutmeg was the most elusive to find and it was also the most valuable."
But a dark history surrounds the spice.
"Hundreds maybe thousands of people died - were slaughtered - fought in battles over this spice," says Mr Milton. "And all to satisfy the tastes of the elite."
The Portuguese found the spice growing on the Banda Islands of Indonesia (Spice Islands) in 1512.
At the time, nutmeg trees grew on only six remote islands in Indonesia and the east indies.
By the early 1600s Dutch troops had control of the nutmeg trade. But in 1616 English trader Nathanial Courthope and his men took over the Island of Run, and struck a deal with native chiefs to ensure the English would keep control of the island and send nutmeg back to the UK.
Today nutmeg trees are grown much more widely. In the Caribbean, the centre of the nutmeg trade is the island of Grenada.
Most of the nutmeg growing there is exported but the spice is also much-used in Grenada in the cuisine and as a medicine. In Grenada "You use it on meat, you use it in soup, you use it in bread, we use it in everything."
Nutmeg has been used as a medicine in some parts of the world for centuries.
In Grenada it is commonly used to treat a range of ailments such as aches and pains and arthritis.
The island's nutmeg industry was devastated in 2004 by hurricane Ivan.
Many trees on the island were flattened and it will still take several more years for new ones to reach full production (around 300lbs of nutmeg from each tree).
One silver lining however is that farmers have reported a better quality of nutmeg being produced by their post-hurricane trees.
Nigel Slater says he would love to see nutmeg regain popularity, and be added to a wider variety of dishes.
"The thing about nutmeg is that it keeps very well. Particularly as a whole spice. It's there. It's sitting in your cupboard."
"Get it out and let's grate it. Let's put it in our white sauce... it's fabulous on cauliflower... let's put it in our cheese sauces. You know, let's bring nutmeg back."
