Apple Celeriac Soup Recipes

Steps:

• Heat the olive oil in a large, heavy soup pot over medium heat and add the onion, leeks and a pinch of salt. Cook, stirring, until tender, about 5 minutes. Add the celeriac and a generous pinch of salt, cover partially and cook for another 5 minutes, stirring often, until the celeriac has begun to soften. Add the potatoes, apples, water or stock, salt to taste, and the bouquet garni. Bring to a boil, reduce the heat, cover and simmer 1 hour, or until the vegetables are very tender and the soup is fragrant. Remove and discard the bouquet garni.
• Blend the soup in batches in a blender (cover the top with a towel and hold it down to avoid hot splashes), or through a food mill fitted with the fine blade. The soup should be very smooth. Strain if desired. Return to the pot. Stir and taste. Adjust salt, add freshly ground pepper, and heat through. Serve in small bowls or espresso cups, garnished with thin slivers of celery leaves.

Steps:

• Melt butter in heavy large pot over medium heat.
• Add celery root, apples, and onion. Cook until apples and some of celery root are translucent (do not brown), stirring often, about 15 minutes.
• Add 4 cups broth. Cover and bring to simmer. Reduce heat to medium-low; simmer covered until celery root and apples are soft, stirring occasionally, about 25 minutes. Remove from heat; cool slightly.
• Working in batches, puree soup in blender until smooth, adding more broth by 1/4 cupfuls to thin to desired consistency. Return soup to pot.
• Season to taste with salt and pepper. DO AHEAD: Can be made 1 day ahead. Refrigerate uncovered until cold, then cover and keep refrigerated.
• Puree chives, grapeseed oil, and pinch of salt in blender until smooth.

• DO AHEAD: Chive oil and pancetta can be made 2 hours ahead. Let stand at room temperature.
• Rewarm soup over medium heat. Divide soup among bowls. Sprinkle pancetta crumbles over each serving. Drizzle each bowl with chive oil.
