Guava-Grapefruit Possets

Simmer cream with sugar, add citrus juice, and then wait for chemistry to kick in. The acidity in the citrus juice works to gently thicken and set the cream into a rich and velvety pudding. With no distracting eggs, cornstarch, or gelatin needed to thicken the possets, you get pure dairy richness primed to showcase the flavors of your choice—in this case, zingy grapefruit and sharp but floral guava. Reducing the cream on the stovetop is not optional—it helps remove excess moisture for perfectly set possets (i.e., spoonable and just barely bound).
