Soak 100g of dried longan in cold water for 15 minutes soaking will help soften it. Drain and set aside Do not soak for much longer than 20 minutes to retain as much flavour as possible
Toast peeled walnuts in a pan on low heat until they are completely dry. Set aside and let cool
Toast black sesame seeds in a pan on low heat until you can smell the slightly sweet aroma and each sesame should have expanded slightly to a rounder shape. This will take approx. 5-8 minutes. Set aside and let cool. You can skip this step if you bought roasted sesame seeds, however, lightly toasting it again can bring out more flavour
Rinse goji berries in cold water. They do not need to be soaked
Toast longan with goji berries on low heat until most of the moisture has evaporated. Set aside and let cool
Remove pits from red dates and set aside I usually cut the meat off with kitchen shears
In a pot, add 250ml water and mix 2 packets of Knox gelatin powder into the water, stir well
Add 80g brown sugar to the gelatin water. Cook until gelatin and water have dissolved and let cool
Pour the cooled gelatin mixture through a sieve and into a mixing bowl, pan or pot

Grease the container that you want the cake to be set in with ½ tsp oil. Use a small piece of kitchen towel or a brush to spread the oil evenly in the container
Pour the entire contents into the container
Cover with a lid or plastic wrap and set in the fridge for approx. 6 hours or until the cake has completely solidified
Remove the cake from the container You may need to use a knife to help loosen the sides
Slice into desired shape and serve. This cake can be stored in the fridge for a week. Can be served cold or at room temperature. I seal and package each piece individually in food-grade wrappers which look nice and can help preserve them in the fridge for 3-4 weeks. I bought “machine seal biscuit bags” on AliExpress along with a mini impulse sealer.
