Ingredients
1 cup sugar
Kosher salt
1 cup lightly packed fresh mint leaves, finely chopped
8 jalapeno or serrano peppers, 2 whole; 6 stemmed, seeded, and minced (2/3 cup)
2/3 cup distilled white vinegar
1 teaspoon calcium water (calcium and instructions included with Pomona's Universal Pectin, below)
1 teaspoon Pomona's Universal Pectin
Preparation
In a saucepan, bring sugar, 1/4 teaspoon salt, mint, whole jalapenos, and 1 cup water to a simmer over medium-high heat, stirring until sugar and salt have dissolved. Simmer 1 minute more. Remove from heat; let cool completely. Strain syrup through a sieve, reserving 1 tablespoon mint before discarding solids.
Meanwhile, in another saucepan, bring vinegar and calcium water to a boil. Remove from heat;stir in minced peppers.
Whisk pectin into 1/4 cup syrup. Add to vinegar-pepper mixture and return to medium-high heat, stirring until mixture returns to a simmer and pectin dissolves, about 30 seconds. Remove from heat. Stir in remaining mint syrup and reserved mint. Transfer mixture to heatproof resealable jars with lids; let cool completely. Cover and refrigerate until set, at least 4 hours and up to 1 month, or follow our canning instructions and store at room temperature up to 1 year.
