Ingredients :

• Egg yolk — The only ingredient where quality really changes everything. A deep orange yolk — a sign of a hen that ate real food — gives a richer, more colorful foam than a pale, anemic one. Buy fresh, free-range eggs if possible. Avoid eggs older than a week for this kind of raw or semi-cooked preparation.
• Coffee — It needs to be strong. An espresso is ideal. A strong Moka pot coffee works very well too. Avoid light filter coffee — the foam would overpower its taste. Rule of thumb: if your ordinary coffee seems too bitter alone, it will be perfect here.
• Sugar or honey — One to two teaspoons. Honey brings a floral note that pairs well with the egg. White sugar gives a more neutral result. Don’t skip this step — sugar isn’t just for sweetness, it helps the foam take shape and hold its structure.
• Cinnamon (optional) — A pinch on top just before serving. The warm, slightly peppery aroma of cinnamon complements the egg and coffee in a way that’s hard to explain but very pleasant. If you don’t have it, no big deal. If you do, don’t miss out.
