Ingredients

3 cups white-wine vinegar 

1 1/2 teaspoons whole coriander seeds 

6 strips (1 inch wide) fresh lemon zest 

2 bay leaves 

Coarse salt 

1/3 cup sugar 

4 bunches spring onions (red or white), trimmed to height of a 1-quart jar 

1 bunch thin asparagus, trimmed to height of a 1-quart jar 

Preparation

Bring 3 3/4 cups water, the vinegar, coriander seeds, lemon zest, bay leaves, 2 tablespoons salt, and the sugar to a boil in a medium saucepan. Add onions, and return to a boil. Reduce heat, and simmer 4 minutes.

Divide asparagus between two 1-quart jars. Add onions, and divide liquid between jars. Let cool to room temperature, about 1 hour. Cover, and refrigerate at least 1 day and up to 1 month.
