Ingredients
Canola oil, for molds
3/4 cup sugar
1/2 cup packed fresh mint leaves, plus 6 small leaves or sprigs for mold
1 tablespoon plus 1 teaspoon unflavored gelatin (about 1 1/2 envelopes)
1 1/2 cups fresh lowbush or small regular blueberries (about 8 ounces), plus more for garnish
Whipped cream, for serving (optional)
Preparation
Lightly oil six 4-ounce round or oval molds. Bring sugar, mint, and 2 cups water to a boil in a small saucepan, stirring until sugar has dissolved. Reduce to a simmer, and cook 5 minutes. Pour mint syrup through a fine sieve into a medium heatproof bowl; discard solids.
Put 1/4 cup cold water into a medium bowl; sprinkle with gelatin. Let stand until evenly moistened, about 1 minute. Add mint syrup, whisking until gelatin has dissolved. Gently stir in berries.
Put a small mint leaf or sprig into each mold. Using a ladle, evenly divide berries and gelatin mixture among molds. Carefully transfer to a tray or rimmed baking sheet; refrigerate until set, 1 1/2 to 2 hours. Gellies can be refrigerated, covered with plastic wrap, up to 1 day.
Dip bottom of each mold in a shallow dish filled with hot water for about 10 seconds; unmold onto a serving plate, tapping to release. (You can use the tip of a sharp knife to break the seal or return mold to hot water if needed.) Serve immediately with whipped cream if desired. Garnish with berries.
