Soup à la Cantatrice

Ingredients

• 3 oz sago
• 300 ml cream
• 3 egg yolks
• 1 lump sugar
• 1 bay leaf
• 2 quarts medium stock

Method

Sago à la Cantatrice is built on the principle of a cream liaison — the egg yolks and cream must thicken the stock without scrambling. This requires precision in temperature and timing, not guesswork.

Rinse the sago under cold running water to remove surface starch, which would otherwise cloud the finished soup. Bring the stock to a bare simmer — not a rolling boil, which will bruise the delicate grains. Add the sago in a steady stream, stirring constantly to prevent clumping. The grains will sink, then gradually turn translucent as the starch hydrates. After 25–30 minutes, the sago should be completely soft and invisible in the liquid, having surrendered its structure entirely to the broth. Taste the stock at this point — it should taste clean, not starchy.

While the sago finishes, whisk the egg yolks in a separate bowl. Add the bay leaf to the stock now if you haven't already; it will infuse the liquid in the final minutes. Heat the cream to a gentle steam — around 65–70°C — but do not boil it. Slowly pour the hot cream into the whisked yolks whilst whisking constantly. This gradual addition prevents the eggs from cooking into flecks. The mixture should become pale and slightly thickened, visibly thicker than the raw yolks.

Remove the stock from the heat the moment it stops steaming. Add the bay leaf if not already in. Pour the cream-yolk liaison into the hot (not boiling) stock in a thin stream, stirring constantly. The residual heat will emulsification|emulsify the eggs and cream into the liquid, creating a velvety texture — this is the whole point of the dish. If you see any flecks of cooked egg forming, you've overheated; start again with a fresh liaison.

Taste and season with salt, pepper, and a pinch of caster sugar if the stock is underseasoned or acidic. Serve immediately into warmed bowls. Do not reheat or return to the stove; the eggs will break and the soup will separate into greasy, grainy clots.
