Pickled Fennel with Mustard and Peppercorns

Tangy pickled fennel is a good match for fish and seafood. It’s also great with roasted lean meats like chicken and pork.

• 
  
  1/2 tsp. yellow mustard seeds
  
  


• 
  
  1/2 tsp. whole black peppercorns
  
  


• 
  
  1 (1-lb.) fennel bulb, trimmed, cored, and thinly sliced
  
  


• 
  
  1 cup white wine vinegar
  
  


• 
  
  1/2 cup granulated sugar
  
  


• 
  
  3 Tbs. olive oil
  
  


• 
  
  Kosher salt
  
  

Bring an 8-quart pot of water to a boil. Immerse two wide-mouth pint-size canning jars, lids, and bands in the water and boil for 10 minutes to sterilize. With tongs, transfer to a clean dishtowel to drain.


Toast the mustard seeds and peppercorns in a small dry skillet over medium heat until fragrant, 1 to 2 minutes. Grind to a medium-coarse texture in a spice grinder or with a mortar and pestle. Pack the fennel into the jars, layering it with the spice mixture.


In a medium saucepan, bring the vinegar, sugar, oil, 1 Tbs. salt, and 1/2 cup water to a boil over medium heat. Pour the liquid over the fennel until it reaches the top of the jars. Screw on the lids, cool to room temperature, and refrigerate for 3 days before using. The fennel will keep in the refrigerator for at least 2 weeks.
