Velvety, opaque yellow spread coats the back of a spoon cleanly at 160 degrees Fahrenheit, offering a sharp tartness balanced by structural sugar. Pressure cooking applies steady, gentle ambient heat that thickens eggs without scrambling them, eliminating the constant whisking required by a traditional double boiler. Glass mason jars protect the mixture from direct steam contact while conducting heat evenly through the liquid.
Proper refrigeration thickens citrus curd further as butter fats solidify, creating a spreadable texture that holds for up to two weeks in standard home units. Freezing extends shelf life up to three months when stored in airtight containers with a quarter-inch of headspace to allow for expansion. Thaw frozen portions overnight in the main refrigerator compartment rather than on the counter to prevent moisture separation.
