- 1/2 teaspoon coriander seeds
- 1/4 teaspoon fennel seeds
- 1 garlic clove, crushed
- 1 2-inch-wide strip lemon zest
- 1/2 cup heavy cream
- 1 tablespoon buttermilk
- Kosher salt
- 1/4 teaspoon finely grated serrano chile
- 1/2 teaspoon finely grated grapefruit zest
- 2 tablespoons fresh grapefruit juice
- 2 teaspoons fresh lemon juice
- 2 teaspoons red wine vinegar
- 1 teaspoon finely grated peeled ginger
- 1 pound Bibb lettuce, Little Gem, or baby romaine, cut into wedges
- 2 tablespoons assorted seeds (such as sunflower, sesame, and/or poppy)
- Olive oil and Aleppo-style pepper (for serving)
- Toast coriander seeds and fennel seeds in a dry small skillet over medium heat, shaking often, until fragrant, about 2 minutes. Let cool. Using the side of a chef’s knife, lightly crush spices on a cutting board. Transfer to a small bowl and mix in garlic, lemon zest, and cream. Cover and chill 1 hour.
- Strain infused cream through a fine-mesh sieve into a medium bowl; add buttermilk and whisk until soft peaks form. Season with salt, then mix in grated chile.
- Whisk grapefruit juice, lemon juice, vinegar, and ginger in a large bowl and season with salt. Add lettuce wedges to bowl, season with salt, and toss to coat. Arrange lettuce wedges on a platter.
- Using a small spoon, swipe some infused cream over lettuce wedges. Sprinkle with half of assorted seeds, then drizzle with oil and top with Aleppo-style pepper and grapefruit zest.
- Sprinkle remaining assorted seeds over remaining infused cream and serve alongside lettuce wedges for dipping.
