Smen (salted, herbed butter)
Smen: salted butter cooked with za'atar and aged until mellow, the finishing fat of couscous
Atlas households once kept jars of smen for months, even years, until the salted butter developed a pungent, almost blue-cheese aroma; a spoonful stirred into couscous, harira or a chicken tagine gives a depth nothing else can. Long ageing at room temperature is risky at home, so this is a safer fridge version: pasteurised unsalted butter is simmered with dried za'atar or oregano, strained, salted and then matured in the fridge for 2–4 weeks, which gives a mellow, nutty, faintly tangy smen rather than the fiercely strong old kind. For the real long-aged flavour, buy smen from a reputable shop. Use it a teaspoon at a time; it is meant as a seasoning, not a cooking fat. The mistake to avoid is leaving any milk solids or water in the butter, as that is what turns it rancid or mouldy rather than pleasantly aged. Chef's tip: strain it through muslin until perfectly clear; any milky bits left in the jar are what turn butter rancid.

Method
0/6 doneStep 1: Sterilise a 500 ml glass jar: wash, rinse and dry in a 250°F oven for 15 minutes. Leave it to cool.
15 minStep 2: Melt 1 ⅛ lb unsalted butter in a small heavy pan over a low heat. Stir in 1 tbsp dried za'atar or dried oregano.
Step 3: Let the butter simmer very gently without stirring until it stops crackling, the foam on top turns pale and the milk solids at the bottom are light golden, not brown. Skim the foam off with a spoon as it rises.
15 minStep 4: Line a fine sieve with a double layer of muslin and strain the butter into a clean jug. The fat should be completely clear and golden; strain again if not.
Step 5: Stir 1 ½ tsp fine salt into the warm butter until dissolved, then pour into the jar. Let it cool, stirring once or twice as it thickens, so the salt stays evenly spread.
Step 6: Close the jar and keep it in the fridge. It can be used straight away, but after 2–4 weeks it develops a rounder, slightly tangy aroma. Always use a clean, dry spoon, and use within 3 months.

Vegetable brown stock
A hearty stock that's simmered for 2 hours, then blended and strained, so the potato gives it body. Its deeper flavour suits thick soups, gravies and stews. Freeze it in portions so it's ready when you need it.
BabboucheSpiced snail broth
After dark in Marrakech's great square, the babbouche stalls are recognisable by their steaming cauldrons and the toothpicks laid out by every bowl. Small land snails simmer in a dark broth of liquorice root, aniseed, thyme, caraway, bitter orange peel, chilli and a bundle of herbs that sellers say has fifteen ingredients, believed to soothe the stomach and warm you on a cold night. You pick the snails out with a toothpick, then drink the peppery, herbal, faintly sweet broth. At home, buy live snails sold for cooking, already purged by a reputable seller, discard any with broken shells or that do not move or retract when touched, and cook them through for at least 45 minutes. Chef's tip: keep the spices in a muslin bag; the broth stays clear and you avoid crunching on seeds.
Bean sprouts
Sprouting whole green grams makes them crunchier, quicker to cook and more nutritious. All you need is muslin, water and a warm spot, and they're ready in 3–4 days. Use them in salads, bhel, usal and stir-fries. Any other whole pulse sprouts the same way.
