Potage Montespan

Ingredients

Equipment Needed

• •Small heavy saucepan for the tapioca
• •Medium saucepan for the peas
• •5-quart heavy pot
• •Fine-mesh sieve
• •Flexible heatproof spatula
• •2-cup liquid measure

Instructions

1. 1

   Hydrate the tapioca

   Combine the tapioca, 1½ cups (355 ml) of the cold water, and ¼ teaspoon of the salt in a small heavy saucepan. Leave it for 15 minutes so the pearls begin hydrating evenly, then bring it slowly to a quiet simmer, stirring often with a flexible spatula. Lower the heat and cook for 15 to 20 minutes, until every pearl is translucent and the mixture is somewhat thick but still spoonable. If it tightens while opaque centres remain, don’t raise the heat. Ça se rattrape: add the reserved cold water one tablespoon at a time and keep cooking gently. When the pearls are clear, add only enough remaining water to give exactly 2 cups (475 ml) of thick cooked tapioca.

   Judge the tapioca by sight, not solely by the clock. Different brands vary in size, but an opaque white point in the centre always means the pearl needs more gentle cooking.
2. 2

   Cook peas à l’anglaise

   Bring a medium saucepan of water to a full boil and season it with the remaining 2 teaspoons salt. Add the peas and cook until just tender, about 2 to 3 minutes for fresh peas or 60 to 90 seconds for frozen petite peas. Drain them thoroughly, return them to the warm dry pan, and turn them through the butter. This is à l’anglaise, cooked briskly in salted water, drained, and finished with butter. Keep them warm without further cooking; wrinkled, grey peas have stayed in the pan too long.

3. 3

   Warm the asparagus cream

   Put the 6 cups Crème d’Asperges, otherwise Argenteuil (No. 697) in a heavy 5-quart pot and warm it over medium-low heat, stirring across the bottom and into the corners. Bring it only to the point where the surface quivers. Do not boil it. If a skin formed while the soup was chilled, whisk it smooth before applying stronger heat rather than trying to beat it out once the cream is hot.

4. 4

   Fold in tapioca

   Add the 2 cups of somewhat thick tapioca to the 6 cups of warm asparagus cream, keeping the book’s exact three-to-one ratio. Fold slowly with a spatula until the texture is even, then hold the Potage below a simmer for 3 to 5 minutes so the two preparations settle into one another. It should fall from the ladle in a broad, smooth ribbon, not sit like porridge. If it is too tight, stir in hot water one tablespoon at a time, up to ½ cup. If it seems a little loose, wait two minutes before changing anything, because tapioca continues thickening as it stands.

5. 5

   Garnish and serve

   Taste the Potage and correct the salt only if needed, remembering that the finished Crème d’Asperges, otherwise Argenteuil (No. 697) is already seasoned. Fold most of the warm peas à l’anglaise through the soup without crushing them. Ladle into warmed bowls and distribute the remaining peas over the surface so each serving receives its proper garnish. Serve immediately, while the soup is supple and the peas are still bright. À table!

Chef Tips

• •Crème d’Asperges, otherwise Argenteuil (No. 697) is a finished referenced component, exactly as the book treats it. Prepare it by its own formula rather than rebuilding it inside this recipe. The timing here begins once that component is ready.
• •Use small pearl tapioca. Instant tapioca dissolves too quickly and can make the soup pasty, while large drinking pearls belong to another table entirely. The little pearls should become translucent and nearly disappear into the cream.
• •Fresh peas are lovely when they are genuinely young. Outside their good season, frozen petite peas are the honest classical-pantry answer because they were preserved while sweet and tender.
• •The source adds thick tapioca to a completed cream soup. It does not replace the foundation within the Argenteuil base; it supplies the Montespan variation’s extra body without introducing another flour thickener.
• •For a dinner party, serve modest first-course portions and pair the Potage with a dry Loire Sauvignon Blanc. Its freshness suits asparagus better than a heavily oaked wine.

Advance Preparation

• •Prepare the Crème d’Asperges, otherwise Argenteuil (No. 697) up to one day ahead, cool it promptly, and keep it covered in the cold. Warm it gently before assembling the Potage.
• •The tapioca can be cooked earlier the same day, cooled promptly, covered directly against its surface, and refrigerated. Reheat it over low heat with a spoonful of water until supple before measuring the required 2 cups.
• •Blanch the peas several hours ahead only if service demands it. Cool them immediately in cold water, drain and dry them well, then warm them briefly with the butter just before they enter the soup.
• •Leftover Potage keeps for two days in the cold but thickens considerably. Reheat it gently without boiling and restore its pouring consistency with hot water, one spoonful at a time.
