This free online class, taught by the UC Master Food Preservers Online Delivery Program, focuses on food safety principles and practical techniques for making marmalade at home.

You’ll learn how different citrus varieties, such as oranges, lemons, and grapefruit, affect flavor, texture, and finished marmalade quality. The class compares traditional marmalade methods with quicker approaches using added pectin, with an emphasis on the science and safety behind each process.

Presenters will also cover common marmalade problems, such as bitterness or setting issues, and share practical ideas for using marmalade in both sweet and savory dishes.
