To Make Quick Sorrel Jelly: in a medium-sized saucepan, bring juice to a simmer over medium-high heat. Whisk in the pectin and whisking occasionally, bring to a rolling boil. Add sugar, whisking until dissolved, about 5 minutes. Cook on high for another 10 to 15 minutes. Carefully cool the jars with the jelly, cover tightly and allow to cool before storing in the fridge.
To Make Spiced Thumbprint Cookies: Position a rack in the upper third of the oven and a second rack in the lower third, then preheat to 350 degrees F. Line 2 baking sheets with parchment paper.
