Cauliflower Soup with Capers and Lemon

Ingredients

Equipment Needed

• •Large Dutch oven or heavy-bottomed pot
• •Blender or immersion blender
• •Small skillet for crisping capers
• •Microplane or fine grater for lemon zest

Instructions

1. 1

   Soften the aromatics

   Warm the olive oil in a large Dutch oven or heavy pot over medium heat. Add the sliced onion and a pinch of salt. Cook slowly, stirring occasionally, until the onion is soft and translucent but not browned, about eight minutes. You want sweetness here, not caramelization. Add the smashed garlic and cook another minute until fragrant.

   If your onion starts to color, lower the heat. Browning will change the soup's clean, ivory appearance.
2. 2

   Simmer the cauliflower

   Add the cauliflower florets and stock to the pot. The liquid should just cover the vegetables. If it does not, add a splash of water. Bring to a gentle simmer, then reduce heat to maintain lazy bubbles. Cook uncovered for twenty to twenty-five minutes until the cauliflower is completely tender. It should offer no resistance when pierced with a knife.

   Truly tender cauliflower is the difference between silky soup and grainy soup. Do not rush this step.
3. 3

   Blend until silky

   Remove the pot from heat and let cool for five minutes. Working in batches, transfer the soup to a blender and puree until completely smooth, at least ninety seconds per batch. The longer you blend, the more luxurious the texture. Return the soup to the pot. Alternatively, use an immersion blender directly in the pot, though the texture will be slightly less refined.

4. 4

   Season and brighten

   Warm the soup over low heat. Stir in the lemon juice and taste. The soup should be slightly under-seasoned at this point because the capers will add their own salinity. Add salt carefully. The soup should taste clean and sweet with a gentle backdrop of onion and garlic.

5. 5

   Crisp the capers

   While the soup warms, heat a small skillet over medium-high heat with a thin film of olive oil. Add the drained capers in a single layer. They will sputter and pop. Let them fry undisturbed for about two minutes until they open like tiny flowers and turn crisp at the edges. Transfer immediately to a paper towel.

   Patting capers dry before frying prevents dangerous splattering and helps them crisp properly.

   Serve with care

   Ladle the warm soup into bowls. Scatter the fried capers over each portion along with the lemon zest, a few parsley leaves, and a generous drizzle of your best olive oil. A few grinds of black pepper. Let things taste of what they are. Serve immediately while the soup still holds its warmth and the capers their crunch.

Chef Tips

• •Seek out cauliflower at farmers markets in autumn and winter when it is in season. The heads should feel dense, with no soft spots or browning. The leaves tell the story of freshness.
• •Homemade stock transforms this soup. If you must use store-bought, choose one with a short ingredient list and low sodium so you control the seasoning.
• •Salt-packed capers have better flavor than brined ones. Rinse them well and soak briefly in cold water before draining and frying.
• •The olive oil you drizzle at the end matters more than the one you cook with. Use something grassy and fresh that you would happily dip bread into.
• •This soup wants crusty bread. Toast thick slices, rub with raw garlic, and let them soak up the broth.

Advance Preparation

• •The soup base can be made up to three days ahead and refrigerated. It thickens as it sits. Thin with a splash of stock when reheating.
• •Crisp the capers fresh just before serving. They lose their crunch within minutes.
• •Zest the lemon just before serving for the brightest fragrance.
