Blackberries make unusual but terrific pickles. The bourbon adds a smoky-sweet flavor to the brine, which makes a great mixer, or even granita! Look for firm but ripe blackberries, with no bruised spots, and you'll be set to make a sweet and tart treat to sip on for the rest of summer.

What you'll need: 3/4 cup sugar 1 tsp cracked black peppercorns 4, 2-inch strips orange zest 3/4 cup distilled white vinegar 1/4 cup plus 2 tablespoons water 1/4 cup bourbon 2 pints firm but ripe blackberries

Equipment: small saucepan 2 pint jars

Recipe steps:

  1. In a small saucepan, mash the sugar, black peppercorns and two orange zest strips until the sugar is slightly colored, about 1 minute. Add vinegar and water and bring to a boil. Remove from heat and let sit 10 minutes.

  2. Pack berries and remaining orange zest into 2 clean pint-size jars. Return brine to a boil. Strain brine into jars and let cool at room temperature. Add bourbon between jars, seal, and refrigerate overnight. Enjoy!
