Combine strawberries with sugar and peppercorns in a quart jar or tightly sealed glass container. Shake well to combine.
Chill for at least 2 hours or up to 1 day in the fridge.
Then add vinegar to the jar, shake to combine, and chill in the fridge for another 2 days.
Strain out the solids using tight-weave cheesecloth or a fine mesh sieve and pour syrup into a clean glass bottle for storage.
Let the syrup sit for a week in the fridge to so flavors can mature.
No alcohol? No problem. We love shrubs sans spirits as a fancy drink when we have people over for cocktails. To make mocktails, add 2 to 3 tablespoons shrub syrup to 8 ounces club soda.
For a more spirited drink, stir together 1 ounce tequila or vodka and 2 tablespoons shrub syrup, pour over ice and top off with club soda. Garnish with a fresh or repurposed pickled berry.
