Ingredients

Equipment Needed

• •4-quart (3.8-liter) heavy saucepan
• •3-quart (2.8-liter) clean saucepan for the strained soup
• •8-inch (20-cm) fine-mesh sieve
• •Immersion blender
• •Whisk and ladle
• •Kettle and toaster or broiler
• •2-quart warmed soup tureen
• •Instant-read thermometer, optional

Instructions

1. 1

   Ready the whole service

   Bring the measured water to a full boil in a kettle. Set the fine-mesh sieve over the clean saucepan, warm the soup tureen with hot water, and whisk the yolks with all but 2 tablespoons of the cold cream; return that bowl and the reserved cream to the cold. Toast the 8 bread slices until dry and pale gold, brush them with 2 tablespoons of the butter, then empty and dry the tureen and arrange the bread inside. Keep the whitebait cold. Once the onion enters the pan, the clock is running.

2. 2

   Sweat onion without color

   Melt the remaining 4 tablespoons butter in the heavy saucepan over medium-low heat. Add the onion and cook for 2 to 3 minutes, stirring steadily, until supple and translucent but not golden. Stir in the curry powder for 20 seconds, just until fragrant. If an edge begins to color, pull the pan from the heat and add a spoonful of the boiling water at once; it cannot erase the brown, but it stops the browning before it overtakes this pale soup.

3. 3

   Boil the bread base

   Pour in the boiling water, then add the bouquet garni, salt, saffron, and torn bread. Bring the mixture to an active boil and cook uncovered for exactly 10 minutes, stirring twice and pressing the bread against the side of the pan so it dissolves into the liquid. If bread settles onto the bottom, scrape it free and moderate the heat slightly, but keep a true boil rather than a timid simmer.

4. 4

   Cook whitebait briskly

   Add the cold, well-drained whitebait all at once and raise the heat. Return the soup to a brisk boil as quickly as possible, then cook for 90 seconds to 2 minutes, stirring once, until the tiny fish are opaque and break readily beneath the spoon. Remove the bouquet garni. The fish are minute and cook through quickly; extending this stage makes their flavor coarse and steals the time needed for straining and liaison.

5. 5

   Blend and pass fine

   Take the pot from the heat. Submerge the immersion blender fully and blend for 20 to 30 seconds, until the soup looks uniform. Pass it immediately through the prepared fine-mesh sieve into the clean saucepan, pressing firmly with a ladle until only dry, gritty bones and skin remain; do not force the last sharp grit through. The hair sieve was equipment, but the fine pass is not optional. It is what turns whole blanchaille into velouté.

6. 6

   Temper the liaison

   Whisk about 1 cup of the hot strained soup gradually into the yolk-and-cream mixture. Pour this tempered liaison back into the saucepan in a thin stream while stirring continuously. The residual heat should thicken the soup enough to leave a light coat on the spoon; it should remain between 160 and 170°F (71 and 77°C), never boil. If it is cooler, set it over low heat and stir without stopping. At the first grainy flecks or greasy separation, remove it from the heat, whisk in the reserved cold cream, blend for 5 seconds, and pass it once more. Ça se rattrape. If it remains smooth, stir in the reserved cream off the heat.

7. 7

   Pour and serve now

   Taste once and correct the salt only if needed. Pour the velouté directly over the dried buttered bread in the warm tureen and carry it straight to the table. Do not cover it, hold it beside the stove, or plan to reheat it; the liaison and puréed fish will turn if left waiting. Ladle it while the surface is still glossy. À table!

Chef Tips

• •Blanchaille names a size and market category, not a single species. Ask for tiny whole whitebait with firm bodies and a clean sea smell. If they smell strong or soften in the bag, change the plan; this particular velouté depends on impeccable fish.
• •Pain viennois supplies the fine, tender crumb specified by the formula. If it is unavailable, unsweetened pain de mie is the honest equivalent because it thickens without announcing itself; sourdough or heavily seeded bread changes the soup entirely.
• •Use a mild, fresh curry powder and measure it. Currie should sit behind the saffron and fish, not turn the pot into a spice soup. Cook it only until fragrant, because darkly toasted curry would muddy both the color and the flavor.
• •The original service also permits cooked rice or previously poached vermicelli instead of dried buttered bread. Choose one accompaniment and put a modest spoonful into each warmed bowl before pouring the velouté.
• •A dry Loire Chenin Blanc has enough acidity for the cream and enough breadth for saffron and curry. Pour it before the fish enters the pot, because there will be no spare hand afterward.
• •This soup is not for storage. If leftovers remain, cool and refrigerate them promptly for safety, but expect the liaison to separate and the fish aroma to strengthen; the intended dish exists only at first service.

Advance Preparation

• •Measure every ingredient, chop the onion, tear the bread, assemble the bouquet garni, and place the blender, sieve, clean saucepan, whisk, and tureen before beginning. Speed here comes from mise en place, not from skipping technique.
• •The serving bread may be dried up to 6 hours ahead and kept uncovered at room temperature. Brush it with butter shortly before arranging it in the warmed tureen.
• •Keep the whitebait covered over ice, without letting it sit in meltwater, and rinse and drain it only shortly before cooking. Whisk the yolks and cream just before starting, then keep the liaison cold.
• •Do not cook the base ahead. Begin only when the guests are seated and the table is ready, because the completed velouté cannot wait.
